It is a reaction between an element and a compound that results in a different element and compound
Answer:
[NaOCl] = 0.1M (option c.)
Explanation:
We determine the reaction:
NaOCl(aq) + HCl (aq) →NaOH (aq) + Cl₂(g)
Ratio is 1:1, so if I produce 0.01 moles of chlorine I used 0.01 mol of hypochlorite.
Our volume of solution by water (solvent) and NaOCl (solute) was 100 mL, so in order to determine molarity we divide moles by volume (L)
100 mL . 1L/1000mL = 0.1L
Molarity → 0.01 mol /0.1L = 0.1M

Answer:
14.8005 Joules
Explanation:
This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:
Q = m × c × ∆T
Where;
Q = amount of heat (Joules)
m = mass of substance (g)
c = specific heat of substance (J/g°C)
∆T = change in temperature of substance i.e. final temperature - initial temperature (°C).
According to this question, the following expression is given:
q = 0.75 g x 0.897 J/g•°C x 22°C
To calculate this further, this will equal to: 14.8005
This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.
<u>Answer:</u> The pressure of the gas inside the vessel is 0.232 atm
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of carbon dioxide = 1.65 g
Molar mass of carbon dioxide = 44 g/mol
Putting values in above equation, we get:
To calculate the pressure of the gas, we use the equation given by ideal gas which follows:
PV=nRT
where,
P = pressure of the gas = ?
V = Volume of the gas = 3.93 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = 0.0375 moles
Putting values in above equation, we get:
Hence, the pressure of the gas inside the vessel is 0.232 atm
