Answer:
HNO3 and NaOH
Explanation:
A neutralization reaction is a reaction that occurs between an acid and a base to form salt and water only.
Neutralization reactions are commonly carried out by method of titration. That is, a measured volume of acid of unknown concentration is made to react with a known volume of standard base solution or vice versa.
Two reactants that could be titrated to obtain sodium nitrate are nitric acid and sodium hydroxide.
The reaction equation is as follows;
HNO3(aq) + NaOH(aq) ----> NaNO3(aq) + H2O
Resulting pressure is 13.6 atm.
<u>Explanation:</u>
Using Ideal gas equation, we can find the pressure of the gases formed in the reaction.
PV = nRT
Number of moles, n = given mass / molar mass = 20 g / 18 g/mol
= 1.11 moles
Volume, V = 2 L
Temperature, T = 25°C + 273 = 298 K
R = gas constant = 0.08206 L atm K⁻¹ mol⁻¹
P = nRT/V
= 1.11×0.08206 ×298 / 2
= 13.6 atm
The answer is
C. Control reaction rate
hope it helps :)
Answer:
174 K
Explanation:
To answer this question we will use the PV=nRT formula, where:
We <u>input the data</u> given by the problem:
- 1.072 atm * 20.0 L = 1.50 mol * 0.082atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
Meaning the correct answer is the fourth option, 174 K.
