how many grams of Al(no2)3 should be added to 1.3L of water to prepare a 2.0M solution
Answers
Answer: 429 grams of \(Al(NO_2)_3\) should be added to 1.3 L of water to prepare 2.0 M solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
\(Molarity=\frac{n}{V_s}\)
where,
n = moles of solute \(Al(NO_2)_3\) = \(\frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{165g/mol}\)
\(V_s\) = volume of solution in Liters
Now put all the given values in the formula of molarity, we get
\(2.0M=\frac{xg}{165g/mol\times 1.3L}\)
\(x=429g\)
Therefore, 429 grams of \(Al(NO_2)_3\) should be added to 1.3 L of water to prepare 2.0 M solution

the molecule bromine monochloride, brcl, has a dipole moment of 0.52 d and a bond length of 2.14 a what atom is ecpected to have a negative charge
Answers
The dipole moment of a molecule is the measure of the distribution of electric charge within a molecule.
In a polar molecule like BrCl, the dipole moment arises due to the difference in electronegativity between the two atoms.
Since chlorine is more electronegative than bromine, the electrons in the bond are not equally shared, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the bromine atom.
The dipole moment of BrCl is 0.52 debye, indicating that the bond has a significant dipole moment.
The direction of the dipole moment is from the partially negative chlorine atom towards the partially positive bromine atom.
Therefore, the chlorine atom is expected to have a partial negative charge.
However, it's important to note that the polarity of a molecule is also influenced by the geometry of the molecule. In the case of BrCl, the linear geometry of the molecule also contributes to its polarity.
The dipole moment of BrCl is aligned with the bond axis, and since the molecule is linear, there is no net dipole moment, and the molecule is non-polar.
Nonetheless, the partial charges still exist and play a role in the reactivity of the molecule.

The Liquified Petroleum Gas (LPG) has the composition of 60% Propane (C 3
H 8
) and 40% Butane (C 4
H 10
) by volume: (a) Find the wet volumetric and gravimetric analysis of the products of combustion when the equivalence ratio (Φ)=1.0. (b) What is the stoichiometric air to fuel ratio for the LPG.
Answers
The balanced combustion reaction for propane can be represented as:
C₃H₈ + (5/2)O₂ → 3CO₂ + 4H₂O
And the balanced combustion reaction for butane can be represented as:
C₄H₁₀ + (6.5)O₂ → 4CO₂ + 5H₂O
Since LPG is composed of 60% propane and 40% butane by volume, we can calculate the wet volumetric and gravimetric analysis based on these proportions.
Wet volumetric analysis:
For the wet volumetric analysis, we consider the volume of the products of combustion relative to the volume of the LPG consumed.
Propane (C₃H₈):
The stoichiometric coefficient of propane in the combustion reaction is 3. Therefore, for every mole of propane burned, we will have 3 moles of CO₂ and 4 moles of H₂O formed.
Butane (C₄H₁₀):
The stoichiometric coefficient of butane in the combustion reaction is 4. Therefore, for every mole of butane burned, we will have 4 moles of CO₂ and 5 moles of H₂O formed.
Considering the initial composition of 60% propane and 40% butane by volume, we can calculate the volumetric composition of the products of combustion:
Volumetric composition of CO₂:
(0.6 * 3) + (0.4 * 4) = 3.6
Volumetric composition of H₂O:
(0.6 * 4) + (0.4 * 5) = 4.6
Therefore, the wet volumetric analysis of the products of combustion is 3.6 parts CO₂ to 4.6 parts H₂O.
Wet gravimetric analysis:
For the wet gravimetric analysis, we consider the mass of the products of combustion relative to the mass of the LPG consumed.
Using the molar masses of the compounds involved in the combustion reaction:
Molar mass of CO₂ = 44 g/mol
Molar mass of H₂O = 18 g/mol
Gravimetric composition of CO₂:
(0.6 * 3 * 44 g/mol) + (0.4 * 4 * 44 g/mol) = 158.4 g
Gravimetric composition of H₂O:
(0.6 * 4 * 18 g/mol) + (0.4 * 5 * 18 g/mol) = 74.4 g
Therefore, the wet gravimetric analysis of the products of combustion is 158.4 grams CO₂ to 74.4 grams H₂O.
(b) The stoichiometric air to fuel ratio for LPG can be determined based on the balanced combustion equations for propane and butane.
For propane (C₃H₈):
C₃H₈ + (5/2)O₂ → 3CO₂ + 4H₂O
The stoichiometric coefficient for propane is 1, which means we need 5/2 moles of O₂ for every mole of propane.
For butane (C₄H₁₀):
C₄H₁₀ + (6.5)O₂ → 4CO₂ + 5H₂O
1. Explain why BCl3 monomer but BH3 exist as B2H6.
Answers
Answer:
See explanation
Explanation:
Both BCl3 and BH3 are electron deficient compounds. In these compounds, boron has six instead of eight electrons surrounding it's outermost shell.
BH3 is able to form a dimmer because of the small size of hydrogen atoms which enable them to be fitted between boron atoms. Large size chlorine atoms can not be fitted between boron atoms hence B2Cl6 does not exist.
suppose you mix 100.0 g of water at 24.5 oc with 75.0 g of water at 73.7 oc. what will be the final temperature of the mixed water, in oc?
Answers
The final temperature of the mixed water will be approximately 311.3°C.
To solve this problem, we can use the principle of heat transfer, which states that heat will flow from the hotter object to the colder object until they reach thermal equilibrium at the same temperature.
The amount of heat lost by the hot water will be equal to the amount of heat gained by the cold water. This can be expressed mathematically as:
Qlost = Qgain
where Q is the amount of heat, and subscripts h and c denote the hot and cold water, respectively.
The amount of heat gained or lost can be calculated using the formula:
Q = m * c * ΔT
where m is the mass of the water, c is the specific heat capacity of water (4.184 J/g°C), and ΔT is the change in temperature.
Let's first calculate the amount of heat lost by the hot water:
Qlost = m_h * c * (T_h - T_f)
where T_f is the final temperature of the mixed water.
Substituting the values given in the problem, we get:
Qlost = 75.0 g * 4.184 J/g°C * (73.7°C - T_f)
Next, let's calculate the amount of heat gained by the cold water:
Qgain = m_c * c * (T_f - T_c)
Substituting the values given in the problem, we get:
Qgain = 100.0 g * 4.184 J/g°C * (T_f - 24.5°C)
Since Qlost = Qgain, we can set the two equations equal to each other and solve for T_f:
75.0 g * 4.184 J/g°C * (73.7°C - T_f) = 100.0 g * 4.184 J/g°C * (T_f - 24.5°C)
Simplifying the equation, we get:
31155 J - 311.55 T_f = 4184 T_f - 102584 J
Combining like terms, we get:
429.55 T_f = 133739 J
Solving for T_f, we get:
T_f = 311.3°C
Therefore, the final temperature of the mixed water will be approximately 311.3°C.

which one of the following is characteristic of a base? group of answer choices has a slippery, soapy feel produces h3o in water is insoluble in water has a sour taste turns blue litmus red
Answers
A base is a type of chemical compound that is characterized by the fact that it has a slippery, soapy feel when touched. The correct option is (a).
The slippery, soapy feel is one of the most distinguishing characteristics of a base, and it is due to the fact that bases are able to react with fats and oils on the skin, creating soap-like substances that feel slippery and greasy to the touch.
Bases are also known for their ability to turn red litmus to blue, which is another common characteristic. This is due to the fact that bases are capable of producing hydroxide ions (\(OH^{-}\)) when they are dissolved in water.
These hydroxide ions are basic in nature, and they are able to neutralize any acidic substances that they come into contact with. As a result, when blue litmus paper treated with an acidic substance will turn red when it comes into contact with a base.
Acidic substances, on the other hand, produce \(H^{+}\) ions when they are dissolved in water. These ions are able to neutralize any basic substances that they come into contact with, and as a result, they will turn litmus paper red.
Overall, bases are a very important class of chemical compounds that are used in a wide range of industrial, scientific, and medical applications.

The Makeham formula to compute the price of a bond is given by A verbal interpretation for K would be that K is the present value of the redemption value C.Provide a verbal interpretation for(C-K)
Answers
Answer:
(i) In a bond amortization schedule, the book value represents the remaining amount of the bond principal that hasn't been paid off at a given point in time. When a bond is first issued, its book value equals its face value. As payments are made over the life of the bond, a portion of these payments reduces the book value. By the end of the bond's life, its book value will be zero, as the entire principal will have been paid off.
(ii) The formula for the book value B at time k, where k is the number of periods elapsed, is B = C + Cg - jan-kj.
Here:
- C is the redemption amount,
- g is the modified coupon rate per period,
- j is the yield rate per period, and
- a_n-kj is the present value of an annuity immediate with n - k periods at the yield rate j.
This formula states that the book value at any time k is the redemption amount plus the present value of the future coupon payments (Cg), minus the present value of the annuity that represents the repayments of the bond (jan-kj).
The amortized amount at time k is the change in the book value from time k-1 to time k, plus the coupon payment at time k. It represents the portion of the bond's principal (and interest) that has been repaid up to time k.
(iii) If K is defined as the present value of the redemption value C, according to the Makeham formula, (C-K) would represent the difference between the redemption value of the bond and its present value. This difference is the amount of interest that will accumulate over the life of the bond. In other words, (C-K) can be interpreted as the total interest that the bondholder will earn from holding the bond until redemption, assuming that all coupon payments are reinvested at the yield rate j.

As a result, 1.5 moles of glycerol absorb about 1.99 Joules of heat when their temperature rises from 25 to 70 degrees Celsius.
What is C3H8O3 also known as?Glycerin is a straightforward polymer. The molecular formula of this solvent is C3H8O3. It is sometimes referred to as glycerine or glycerol.
We can use the following formula to determine how much heat 1.5 moles of glycerol absorbed: q = n × C × ΔT
Glycerol has a specific heat capacity of 2.43 J/g°C. This needs to be divided by the molar mass of glycerol in order to be converted to Joules per mole per degree Celsius:
C = (2.43 J/g°C) / (92.09 g/mol)
C = 0.0264 J/mol°C
The change in temperature can then be calculated as follows:
ΔT = (70°C - 25°C) = 45°C
