A sample of water goes through a temperature change of -74.14 °C while releasing 578.7 joules of heat. The specific heat capacity of water is 4.184 J/(g·°C). What is the mass of this sample? grams (Report your answer using 4 significant figures).
Answer:
[tex] \boxed{ \sf \: m = 1.866 \: grams}[/tex]
Explanation:
Given:
Change in temperature ∆T= -74.14°C
Heat(Energy) released Q= 578.7 joules
Specific heat capacity s = 4.184 J/(g·°C)
To find:
Mass of the sample (m)=?
Solution:
[tex] \sf s= \frac{Q}{m \cdot \Delta T} \\ \sf \: Substituting \: the \: given \: parameters \\ \sf 4.184 = \frac{578.7}{m \times ( - 74.14)} \\ \sf m = \frac{578.7}{4.184 \times ( - 74.14)} \\ \sf m = \frac{578.7}{310.20176} \\ { \sf m = 1.8655 \approx1.866 \: grams}[/tex]
Since, we need the answer in 4 significant figures,
[tex] \boxed{ \sf \: m = 1.866 \: grams}[/tex]

3.Calculate the pH of a 0.250 M solution of potassium phenolate, KC6H5O. Ka for phenol (C6H5OH) is 1.0 x 10-10.
From the statement and the information available in the question, the pH of the solution is 12.2.
What is Ka?The term Ka refers to the acid dissociation constant of a substance, we can obtain this by setting up the ICE table as shown;
C6H5O^- + H2O ⇄ C6H5OH + OH^-
I 0.250 0 0
C -X +X +X
E 0.250 -x x x
Now;
Kb = 1 * 10^-14/ 1.0 x 10-10
Kb = 1 * 10^-4
Kb = [C6H5OH] [OH^-]/[C6H5O^-]
1 * 10^-4 = x^2/ 0.250 -x
1 * 10^-4 (0.250 -x) = x^2
2.5 * 10^-4 - 1 * 10^-4 x = x^2
x^2 + 1 * 10^-4 x - 2.5 * 10^-4 = 0
x=0.016 M
Given that; [C6H5OH] = [OH^-] =x
pOH = -log(0.016 M) = 1.8
pH = 14 - 1.8 = 12.2

How many grams of a gas with a molar mass 36.02 g/mol would be required to occupy a 3979 mL flask at 1.07 atm and 81.7 degrees Celcius? Record your answer in scientific notation to 2 decimal spaces.
A 3979 mL flask is occupied by 5.26 g of a gas with a molar mass of 36.02 g/mol at 1.07 atm and 81.7 °C.
What is an ideal gas?An ideal gas is that whose behavior can be explained using the ideal gas laws.
Step 1. Convert 81.7 °C to Kelvin.We will use the following expression.
K = °C + 273.15 = 81.7 + 273.15 = 354.9 K
Step 2. Calculate the moles of the gas.We will use the ideal gas equation.
P × V = n × R × T
n = P × V / R × T
n = 1.07 atm × 3.979 L / (0.08206 atm.L/mol.K) × 354.9 K = 0.146 mol
Step 3. Calculate the mass of the gas.The molar mass of the gas is 36.02 g/mol.
0.146 mol × 36.02 g/mol = 5.26 g
A 3979 mL flask is occupied by 5.26 g of a gas with a molar mass of 36.02 g/mol at 1.07 atm and 81.7 °C.

Many cigarette lighters contain liquid butane, C4H10, which has a ∆H°ƒ = –147.6 kJ/mol. Using enthalpies of formation, calculate the quantity of heat produced when 1.0 g of butane is completely combusted in air. (Write the equation for the process first)
For cigarette lighters containing liquid butane, C4H10, the quantity of heat produced is mathematically given as
q= -49.2 KJ
What is the quantity of heat produced when 1.0 g of butane is completely combusted in air?Generally, the equation for the Chemical reaction is mathematically given as
C₄H₁₀(l) + 6.5 O₂(g)---->4 CO₂(g) + 5 H₂O(l)
Therefore
dH°r = .(-393.5 ) + 5.(-285.5] - [1.(-147.6 )+6.5.
dH°r = -2853.9 kJ/mol
In conclusion, No.of mole
Nm = 1g/58g/mol
Nm= 0.01724mol
Hence, Heat of combustion
q = dH°r x moles
q = -2853.9 ×0.01724
q= -49.2 KJ

V = volume in liters = 0.950 L
n = moles = 727.2 g x 1 mol CH4 / 16 g = 45.45 moles
R = gas constant = 0.0821 Latm/Kmol
T = temperature in K = 221.9K

Given: 8As + 12H20 —>3H2AsO4- + 3H+ + 5AsH3 What mass of arsenic is required to produce 15.0 mL of 0.0852M H2AsO4-?
A. 0.0359 g
B. 0.255 g
C. 17.0 g
D.1134 g
Answer:
B
Explanation:
From the given chemical equation, we want to determine the mass of arsenic necessary to produce 15.0 mL of 0.0852 M H₂AsO₄⁻.
Find the amount of moles present in 15.0 mL of 0.0852 M H₂AsO₄⁻ solution. Recall that M = mol/L:
[tex]\displaystyle 15.0\text{ mL} \cdot \frac{0.0852\text{ mol H$_2$AsO$_4^-$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.00128\text{ mol H$_2$AsO$_4^-$}[/tex]
With stoichiometric ratios and molecular weights, determine the mass of arsenic necessary:
[tex]\displaystyle 0.00128 \text{ mol H$_2$AsO$_4^-$} \cdot \frac{8\text{ mol As}}{3\text{ mol H$_2$AsO$_4^-$}}\cdot \frac{74.92\text{ g As}}{1\text{ mol As}} = 0.256\text{ g As}[/tex]
In conclusion, the answer is B.
