Answers
The learning activities titled "Hypothesis," "Variables and Hypothesis," and "Constructing a Hypothesis" all share certain similarities and differences. A question that arises in response to an observation is similar to a scientific research question in that both require some level of investigation to achieve an answer. However, scientific research questions are typically more specific and refined, with a defined methodology for obtaining data and verifying results.
The following quotes from the readings illustrate this distinction:"A scientific question is one that can be answered by using scientific investigation. In contrast, an observation question is one that comes in response to observing or experiencing something in the natural world" (Scientific Inquiry: Variables, Hypotheses, and the Scientific Method)."An important feature of a scientific question is that it should be answerable within a reasonable amount of time and with the resources available" (Scientific Inquiry: Variables, Hypotheses, and the Scientific Method)."Research questions can be narrow or broad, depending on the scope of the research" (Constructing a Hypothesis).The concept of variables is crucial to both observation and scientific research questions, but they play different roles depending on where they fall on the continuum. Observation questions are usually less precise and may not require much consideration of variables. On the other hand, scientific research questions are likely to include a rigorous examination of variables and their potential effects."Variables are an essential part of a scientific experiment. They are the things that change in an experiment" (Scientific Inquiry: Variables, Hypotheses, and the Scientific Method)."Variables are important because they can affect the outcome of the research" (Constructing a Hypothesis).In summary, observation questions and scientific research questions share some similarities, but the latter is more specific, has a defined methodology, and may require more consideration of variables.For such more question on Hypothesis

We wish to determine the moles of solid AgCl formed when 50.0 ml of 0.250 M AgNO3 reacts with excess MgCl2 according to the equation below.
2AgNO3(aq) + MgCl2(aq) 2Ag Cl(s) + Mg (NO3)2(aq)
In the previous step you determined 0.0125 mol AgNO3 react. How many moles of AgCl form during the reaction?
Answers
The number of moles of AgCl formed during the reaction is 0.0125 mol.
Given the reaction:2AgNO3(aq) + MgCl2(aq) → 2Ag Cl(s) + Mg (NO3)2(aq)We are supposed to determine the moles of solid AgCl formed when 50.0 ml of 0.250 M AgNO3 reacts with excess MgCl2 and in the previous step, we found that 0.0125 mol of AgNO3 reacts.
We can use the stoichiometry method to find the moles of AgCl formed.
To do so, we will have to balance the given chemical equation and find out the number of moles of AgCl formed from the given reactants.
The balanced chemical equation is:2AgNO3(aq) + MgCl2(aq) → 2Ag Cl(s) + Mg (NO3)2(aq)From the equation, we can say that 2 moles of AgCl form from 2 moles of AgNO3 reacted.
In the previous step, we have found the number of moles of AgNO3 reacted, which is 0.0125 mol.
As per the balanced chemical equation, 2 moles of AgCl form from 2 moles of AgNO3 reacted.
Therefore, the number of moles of AgCl formed = (0.0125 mol AgNO3 reacted × 2 moles AgCl / 2 moles AgNO3) = 0.0125 mol AgCl.
The number of moles of AgCl formed during the reaction is 0.0125 mol.

What volume of acetic acid of density 1.10g/cm3 is needed to react with 250 mL of 0.50M Stronuim hydroxide?
Answers
Answer:
\(V=13.6cm^3\)
Explanation:
Hello,
In this case, given the reaction in which the acetic acid reacts with strontium hydroxide to yield water and strontium acetate:
\(2CH_3COOH+Sr(OH)_2\rightarrow Sr(CH_3COO)_2+2H_2O\)
The first step here is to compute the moles of strontium hydroxide that are reacting given its volume in liters (0.250 L) and concentration:
\(n_{Sr(OH)_2}=0.50mol/L*0.250L=0.125molSr(OH)_2\)
Next, considering the 1:2 mole ratio between the strontium hydroxide and the acetic acid (molar mass = 60 g/mol) we compute the grams of acid that are consumed:
\(m_{CH_3COOH}=0.125molSr(OH)_2*\frac{2molCH_3COOH}{1molSr(OH)_2} *\frac{60gCH_3COOH}{1molCH_3COOH}\\ \\m_{CH_3COOH}=15gCH_3COOH\)
Then, by using the density of the acetic acid, we compute the volume:
\(V=\frac{m}{\rho}=\frac{15g}{1.10g/cm^3} \\ \\V=13.6cm^3\)

CHALLENGE The circles below represent of the large circle, and multiply it by 30. That Earth and the moon. Measure the diameter would be the correct distance from Earth to the moon at this scale. Draw the two circles in the space provided. Use the correct distance you found.● = Earth ●=moon
Answers
To draw the two circles, we would need to draw a smaller circle with a diameter of 2,532.5 miles (representing the moon) and a larger circle with a diameter of 75,974.4 miles (representing the Earth) that is 30 times larger than the smaller circle.
What is the explanation for the above response?If we assume that the larger circle represents the Earth, then the diameter of the Earth would be 30 times the diameter of the smaller circle representing the moon. Let's say that the diameter of the smaller circle is x. Then the diameter of the larger circle (Earth) would be 30 times x or 30x.
To find the correct distance from Earth to the moon at this scale, we need to know the actual distance from Earth to the moon, which is approximately 238,855 miles or 384,400 kilometers. If we divide this distance by the scale factor of 30, we get:
238,855 miles / 30 = 7,961.8 miles
Therefore, the diameter of the smaller circle (moon) would be approximately 7,961.8 miles / π = 2,532.5 miles (rounded to one decimal place). And the diameter of the larger circle (Earth) would be 30 times that or 75,974.4 miles
So, to draw the two circles, we would need to draw a smaller circle with a diameter of 2,532.5 miles (representing the moon) and a larger circle with a diameter of 75,974.4 miles (representing the Earth) that is 30 times larger than the smaller circle.

The concentration of an unknown acid solution with general formula H3A is to be determined by titration with a 0.850 M KOH solution. Determine the concentration of the acid solution given that 38.34 mL of KOH solution were needed to fully neutralize 15.00 mL of the acid solution.
Answers
Answer:
0.7242 M
Explanation:
Step 1:
Data obtained from the question. This include the following:
Molarity of base, KOH (Mb) = 0.850 M
Volume of base, KOH (Vb) = 38.34 mL
Volume of acid, H3A (Va) = 15.00 mL
Molarity of acid, H3A (Ma) =...?
Step 2:
The balanced equation for the reaction. This is given below:
H3A + 3KOH —> K3A + 3H2O
From the balanced equation above,
The mole ratio of the acid, H3A (nA) = 1
The mole ratio of the base, KOH (nB) = 3
Step 3:
Determination of the concentration of the acid, H3A.
The concentration of the acid, H3A can be obtained as follow:
MaVa / MbVb = nA/nB
Ma x 15 / 0.850 x 38.34 = 1/3
Cross multiply
Ma x 15 x 3 = 0.850 x 38.34
Divide both side by 15 x 3
Ma = (0.850 x 38.34) / (15 x 3)
Ma = 0.7242 M
Therefore, the concentration of acid, H3A is 0.7242 M
A typical home instant pot has an internal volume of 6.5 Liters. If the steam inside an instant pot with an internal pressure of 191.0 kPa and a temperature of 750.0 K was released into the atmosphere at 101.3 kPa and 298K, what volume with the steam occupy in the atmosphere?
Answers
We can use the combined gas law to solve this problem.
Combined gas law: P1 V1 / T1 = P2 V2 / T2
(191.0 kPa)(6.5 L) / (750.0 K) = (101.3 kPa)(V2) / (298 K)
Now we solve for V2;
1241.5 / 750 = 101.3 / 298
Now we cross-multiply;
369967 = 75975x
Divide by 75975 on each side;
369967 / 75975 = 75975x / 75975
Round our answer to sig figs;
x (aka V2) = 4.8696 L is the volume occupied by the steam in the atmosphere

If the ΔH = 144 kJ/mol and ΔS = 54 J/K mol for a nonspontaneous reaction, at what temperature does this reaction become spontaneous?
Answers
The reaction becomes spontaneous at approximately 2667 Kelvin.
To determine the temperature at which a nonspontaneous reaction becomes spontaneous, we can use the equation ΔG = ΔH - TΔS, where ΔG is the change in Gibbs free energy, ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
In this case, we are given ΔH = 144 kJ/mol and ΔS = 54 J/K mol. To convert ΔH to J/mol, we multiply by 1000, giving us ΔH = 144,000 J/mol.
To find the temperature at which the reaction becomes spontaneous, we set ΔG to zero, as this is the condition for equilibrium. Thus, we have 0 = ΔH - TΔS.
Rearranging the equation, we have TΔS = ΔH, and substituting the given values, we get T * 54 J/K mol = 144,000 J/mol.
Dividing both sides by 54 J/K mol, we find that T = 144,000 J/mol / 54 J/K mol = 2667 K.
Therefore, the reaction becomes spontaneous at approximately 2667 Kelvin.

The enthalpy of this reaction is 1.48 kJ/mol.
The formula to calculate heat energy is
Q = m × c × ΔT
ΔT = T₂ - T₁
m = mass (grams)m = 191 gramsc = specific heat capacity (J/g °C)
c pure water = 4.184 J/g °CΔT = temperature change (°C)T₁ = initial temperature = 21.00 °CT₂ = final temperature = 24.70 °CQ = heat energy (J)
ΔT = T₂ - T₁ = 24.70 - 21.00 = 3.70 °C
Q = m × c × ΔT
Q = 191 × 4.184 × 3.70
Q = 2,956.83 J
Q = (2,956.83 ÷ 1,000) kJ
Q = 2.96 kJ
The enthalpy ΔH = Q ÷ n
n = number of moles = 2.00 molQ = heat energy = 2.96 kJΔH = enthalpyΔH = Q ÷ n
