Please, someone help me. The previous question was - Ammonium nitrite decomposes to give off nitrogen gas and liquid water. How many grams of ammonium nitrite must have reacted if 2.58 L of gas was collected over water in a gas collecting tube at 21.0°C and 97.8 kPa?
Balanced equation:
Answers
3. The amount of ammonium nitrite that must have reacted is 8.164 grams.
A. If the experiment is done at a significantly higher temperature, the volume of nitrogen gas will increase.B. If the amount of ammonium nitrite is increased, the volume of nitrogen gas will increase. C. If the experiment is not collected over water, the volume of nitrogen gas will remain the same.4a. The limiting reactant is Fe₂(CO₃)₃.
b. The volume of carbon dioxide gas that can be produced is 619 milliliters.
What mass of ammonium nitrite reacted?First, the number of moles of nitrogen gas using the ideal gas law:
PV = nRT
where:
P is pressure (in atm) = 97.8 kPa = 97.8/101.3 = 0.965 atm
V is volume (in liters) = 2.58 L
n is number of moles
R is gas constant = 0.0821 L·atm/(mol·K)
T is temperature (in Kelvin) = 21.0°C + 273.15 = 294.15 K
Solving for n:
n = (PV) / (RT)
n = (0.965 atm * 2.58 L) / (0.0821 L·atm/(mol·K) * 294.15 K)
n ≈ 0.102 moles of nitrogen gas
The moles of ammonium nitrite that reacted from the balanced chemical equation:
NH₄NO₂ → N₂ + 2H₂O
From the mole ratio above, one mole of ammonium nitrite reacts to produce one mole of nitrogen gas
Therefore, the moles of ammonium nitrite reacted is 0.102 moles.
So, the mass of ammonium nitrite that reacted is:
Mass = moles * molar mass
Mass = 0.102 moles * 80.04 g/mol
Mass ≈ 8.164 g
4a. Moles of H₃PO₄ = volume (in liters) * molarity
= 0.900 L * 3.00 mol/L
Moles of H₃PO₄ = 2.70 mol
Moles of Fe₂(CO₃)₃ = mass / molar mass
= 235 g / (2 * 55.85 g/mol + 3 * 12.01 g/mol + 9 * 16.00 g/mol)
= 235 g / 291.88 g/mol
Moles of Fe₂(CO₃)₃ = 0.804 mol
Therefore, Fe₂(CO₃)₃ is the limiting reactant.
b. From the balanced equation: 1 mol Fe₂(CO₃)₃ produces 3 moles of CO₂
Moles of CO₂ = 0.804 mol * 3
Moles of CO₂ = 2.412 moles
the volume of CO₂ will be:
PV = nRT
Where:
P is pressure = 45.5 psi or 3.099 atm
V is volume (in liters)
n is the number of moles = 2.412 mol
R is gas constant = 0.0821 L·atm/(mol·K)
T is temperature (in Kelvin) = 78°C + 273.15 = 351.15 K
Solving for V:
V = (nRT) / P
V = (2.412 mol * 0.0821 * 351.15/ 3.099
V ≈ 0.619 L = 619 mL

In a laboratory experiment, the reaction of 3.0 mol of H2 with 2.0 mol of I2 produced 1.0 mol of HI. Determine the theoretical number of moles that could be produced in this reaction.
Answers
The reaction that is occurring in this question is:
H2 + I2 -> 2 HI
As we can see, the molar ratio for H2 and I2 is 1:1, one mole of H2 for each mole of I2, and the molar ratio between any reactant and HI is 1:2, which means the number of moles of product will be two times more than the number of moles of the reactants
We have:
3.0 moles of H2
2.0 moles of I2
1.0 moles of HI
According to the molar ratio, we should have the name number of moles of I2 and H2, which means that H2 is in excess and I2 is the limiting reactant with 2 moles
If we have 2 moles of I2, and the molar ratio of I2 and HI is 1:2, we should have 4 moles of HI being produced
Therefore the theoretical number of moles is 4.0 moles of HI from 2.0 moles of I2

determine the new temperature in °c for a sample of neon with the initial volume of 2.5 l at 15 °c, when the volume is changed to 3550 ml. pressure is held constant.
a. -252 °C b. 21.3 °C c. 136 °C d. 294 °C e. 409 °C
Answers
The new temperature in °C for the sample of neon is 21.3 °C.
The correct answer is b. 21.3 °C.
To solve this problem, we can use the formula for the ideal gas law:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.
Since the pressure is held constant, we can simplify the equation to:
V1/T1 = V2/T2
where V1 is the initial volume, T1 is the initial temperature, V2 is the final volume, and T2 is the final temperature.
Plugging in the given values, we get:
2.5 L / (15 + 273.15 K) = 3550 mL / T2
Solving for T2, we get:
T2 = (3550 mL / 2.5 L) * (15 + 273.15 K) = 21.3 °C

Pb(Cl)4
This means that for every mole of lead(IV) chloride present, there are four moles of chloride ions available. 349g/mol is the molar mass. The chloride moles are then:
\(9.73g \times \frac{1mol}{349g} \times \frac{4mol \: { cl}^{ - } }{1mol \: {pbcl}4 } = 0.1115mol \: {cl}^{ - } \)

Which bonding type results in stronger bonds? What is your evidence?
Answers
Answer:
Covalent bonds are the strongest bonds in nature and under normal biological conditions have to be broken with the help of enzymes. This is due to the even sharing of electrons between the bonded atoms and as with anything equally shared there is no conflict to weaken the arrangement.
Explanation:
Bonding electrons are described as electrons that participate in chemical bonds. Chemical bond, a strong attraction between atoms, ions, or molecules, might be the subject here. Atoms sharing electron pairs form a covalent or molecular connection. An attraction between the atomic orbitals of atoms in a molecule is called a bonding molecular orbital.
Which bonding type results in stronger bonds? What is your evidence?
A covalent bond is created when the difference between two atoms' electronegativities is too small for an electron transfer to occur and produce ions. Bonding electrons are collectively referred to as the electrons that are present between the two nuclei. The "glue" that binds the atoms into molecular structures is the bound pair.
It is the most powerful link. By sharing an electron, the two atoms in such a bond are joined together.
One Hydrogen atom with one valence electron and one Chlorine atom with seven valence electrons, for instance, make up the HCL molecule. In this instance, hydrogen and chlorine share an electron to create a single bond.

Answers
A gas cylinder containing 15 moles of oxygen gas (O2) would contain a total of 9.03 x 10^23 molecules of oxygen. This can be calculated by multiplying the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) as follows:
Number of molecules = 15 moles x 6.022 x 10^23 molecules/mol = 9.03 x 10^23 molecules
For the sample of sugar (C12H22O11), the number of molecules given (1.505 x 10^23 molecules) can be converted to moles by dividing by Avogadro's number as follows:
Number of moles = 1.505 x 10^23 molecules ÷ 6.022 x 10^23 molecules/mol
Without doing any calculations, we can see that the numerator (1.505 x 10^23) is approximately 2.5 times smaller than the denominator (6.022 x 10^23). Therefore, the number of moles of sugar in the sample is less than 1 mole and can be estimated to be about 0.25 moles.

The mole of HCl produced is 0.26 mole.
The mole of MgCl₂ that reacted is 0.13 mole.
The mass of MgCl₂ that reacted is 12.38 grams.
Stoichiometric problemFrom the equation of the reaction:
MgCl₂(s) + H₂O(g) → MgO(s) + 2HCl(g)
The mole ratio of MgCl₂ and HCl is 1:2, while the mole ratio of H₂O and HCl is also 1:2.
5.85 L of HCl was produced. Based on the assumption that the gas was produced at STP.
1 mole of gas at STP = 22.4 L
Thus, 5.85 L of HCl would be equivalent to:
5.85 x 1/22.4 = 0.26 mole.
In other words, the mole of HCl produced is 0.26 mole.
The moles of MgCl₂ produced can be obtained from the mole ratio of MgCl₂ and HCl (2:1):
0.26/2 = 0.13 mole
The mass of MgCl₂ produced can be obtained from the formula:
mass = mole x molar mass
Molar mass of MgCl₂ = 95.211 g/mol
mass of 0.13 mole MgCl₂ = 0.13 x 95.211
= 12.38 grams

1. Trifluoroacetic acid (CF3COOH) - This compound has strong electron-withdrawing fluorine atoms attached to the carbonyl group, making the conjugate base more stable through resonance delocalization of the negative charge.
2. Chloroacetic acid (ClCH2COOH) - The chlorine atom also has some electron-withdrawing effects, but not as strong as fluorine. The conjugate base is still relatively stable due to resonance.
3. Acetic acid (CH3COOH) - This compound has a weaker electron-withdrawing effect than the previous two due to the presence of a methyl group. The conjugate base is stabilized through resonance, but not as much as the previous two compounds.
4. Phenol (C6H5OH) - While phenol has a relatively acidic hydrogen atom, it is not as strong as the previous three compounds due to the stability of the conjugate base being limited by the lone pair on the oxygen atom rather than resonance.
5. Methanol (CH3OH) - Methanol has a relatively weak acidity as its conjugate base is stabilized through hydrogen bonding rather than resonance.
