Answer:
See Explanation
Explanation:
The equation of the reaction is as follws;
4 C3H5(NO3)3 (l) → 12 CO2 (g) + 10 H2O (l) + 6 N2 (g) + O2 (g)
Number of moles of C3H5(NO3)3 = 187.4g /227 g/mol = 0.82555 moles
If 4 moles of C3H5(NO3)3 yields 12 moles of CO2
0.83 moles of C3H5(NO3)3 yields 0.82555 * 12/4 = 2.47665 moles of CO2
mass of CO2 produced = 2.47665 moles * 44 g/mol = 108.95 g of CO2
4 moles of C3H5(NO3)3 yields 10 moles of water
0.83 moles of C3H5(NO3)3 yields 0.82555 * 10/4 = 2.063875 moles of water
Mass of water = 2.063875 moles of water * 18 g/mol = 37.16 g
4 moles of C3H5(NO3)3 yields 1 mole of O2
0.83 moles of C3H5(NO3)3 yields 0.82555 * 1/4 = 0.2063875 moles of O2
Mass of O2 = 0.2063875 moles of O2 * 32 g/mol = 6.6 g
4 moles of C3H5(NO3)3 yields 6 moles of N2
0.83 moles of C3H5(NO3)3 yields 0.82555 * 6/4 = 1.238325 moles of N2
Mass of N2= 1.238325 moles of N2 * 28 g/mol = 34.67 g
To verify the law of conservation of mass, the total sum of mass of products must equal the sum of the mass of reactants. Thus;
108.95 g + 37.16 g + 6.6 g + 34.67 g = 187.4 g
The law of conservation of mass has been proven!

What is the empirical formula of a compound containing 90 grams carbon, 11 grams hydrogen, and 35 grams nitrogen? (5 points)
Question 3 options:
1)
C3H4N
2)
C2H4N
3)
C4H10N
4)
C2H5N
Answers
Answer:
1) C₃H₄N
Explanation:
The empirical formula of a compound is the formula that gives the positive integer ratio of the atoms of the elements in the compound in the simplest form
The mass of carbon in the compound = 90 grams
The molar mass of carbon = 12.011 g/mol
The number of moles of carbon = 90 g/(12.011 g/mol) ≈ 7.4931313 moles
The mass of hydrogen in the compound = 11 grams
The molar mass of hydrogen = 1.00794 g/mol
The number of moles of carbon = 11 g/(1.00794 g/mol) ≈ 10.913348 moles
The mass of nitrogen in the compound = 35 grams
The molar mass of nitrogen = 14.0067 g/mol
The number of moles of carbon = 35 g/(14.0067 g/mol) ≈ 2.49880414 moles
Dividing by the smallest mole ratio gives;
The proportion of carbon, C = 7.4931313/2.49880414 = 2.9987 ≈ 3
The proportion of nitrogen, N = 10.913348 /2.49880414 = 4.367 ≈ 4
The proportion of nitrogen, N = 2.49880414 /2.49880414 = 1
Therefore, the empirical formula of the compound is C₃H₄N.

What is the volume of 0.150 M sodium hydroxide, required to react completely with 250.0 mL of 0.545 M acetic acid, CH3COOH solution?
Answers
Answer:
68.81ml
Explanation:
Using the formula:
CaVa = CbVb
Where;
Ca = concentration of acid (M)
Cb = concentration of base (M)
Va = volume of acid (ml)
Vb = volume of base (ml)
Based on the information given in this question;
Ca = 0.545M
Cb = 0.150M
Va = 250ml
Vb = ?
Using CaVa = CbVb
0.545/250 = 0.150/Vb
Cross multiply
250 × 0.150 = 0.545Vb
37.5 = 0.545Vb
Vb = 37.5/0.545
Vb = 68.81ml

Explain the volume of ideal gasses as related to the molar concept.
Answers
Answer:
n = Initial volume/22.4L
Explanation:
The molar concept is simply one that is used to find the Number of moles and explain the relationship it has with avogadro's number, molecular mass, molar mass e.t.c.
Now, in terms of molar mass, number of moles is given by the formula;
n = mass of the sample/molar mass
In terms of avogadro's number, number of moles is;
1 mole = avogadro's number = 6.02 × 10^(23)
Now, when dealing with ideal gases, the molar volume of an ideal gas is 22.4 L.
Now the relationship between this volume and the mole concept is that the number of moles is gotten by dividing the initial volume by this molar volume.
Thus;
n = Initial volume/22.4L

3) What is the final temperature of a substance if 1404 J of energy is added to 38 g of it at 26°C? The specific heat is 0.24 J/g°C
Answers
Answer:
1. 66.96°C
2. -1776.5J
3. 179.9°C
Explanation:
Using the formula;
Q = m × c × ∆T
Where;
Q = amount of heat (J)
m = mass (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
QUESTION 1:
∆T = ?
m = 160g
c = 0.14 J/g°C
Q = 1500 J
1500 = 160 × 0.14 × ∆T
1500 = 22.4∆T
∆T = 1500/22.4
∆T = 66.96°C
QUESTION 2:
Q = ?
m = 85g
c = 0.11 J/g°C
∆T = 10°C - 200°C = -190°C
Q = 85 × 0.11 × -190
Q = -1776.5J
QUESTION 3:
Q = 1404 J
m = 38g
c = 0.24 J/g°C
Final temperature = ?
Initial temperature = 26°C
1404 = 38 × 0.24 × (T2 - 26)
1404 = 9.12 (T2 - 26)
1404 = 9.12T2 - 237.12
9.12T2 = 1404 + 237.12
9.12T2 = 1641.12
T2 = 1641.12 ÷ 9.12
T2 = 179.9°C
Which of these compounds has the greatest percentage of nitrogen? NO2 N2O4 N3O6
Answers
Answer:
Same in all compounds
Explanation:
We know that
mass percentage of N = [mass of N/ mass of compound] ×100
In NO2, N% = 14/(14+32)×100
= 14/46×100
= 30.43%
In, N2O4, N% = 28/(28+64) ×100 = 28/92×100 =30.43%
Similarly, in N3O6 also the % of N = 30.43%
So, percentage of Nitrogen is same in all given compound. That is 30.43%

A. The pH will gradually approach 4.76.
B. The pH will initially remain close to 4.76, then increase quickly when the buffering capacity is exceeded
C. The PH will initially remain close to 4.76 then decrease quickly when the buffer capacity is exceeded
D. The pH will remain close to 4.76 indefinitely
Answers
the answer is C.
The PH will initially remain close to 4.76 then decrease quickly when the buffer capacity is exceeded
The acidity or alkalinity of a solution depends upon its hydronium ion concentration and hydroxide ion concentration. The pH will initially remain close to 4.76 then decrease quickly when the buffer capacity is exceeded when dil. HCl is added. The correct option is C.
What is pH?The pH of a solution is defined as the negative logarithm to the base 10 of the value of the hydronium ion concentration in moles per litre. For an acidic solution the pH of the solution is less than 7 and for basic solution the pH is greater than 7.
The pH scale is introduced by the Sorensen is more convenient in expressing the hydronium ion concentration of a solution. The PH will initially remain close to 4.76 then it is suddenly decreases if the buffer capacity is exceeded.
The equation used to calculate the pH is:
pH = -log [H₃O⁺]
Thus the correct option is C.
