Answer:
Option C; NONE.
Explanation:
A chemical reaction forms new chemicals called the products from the initial chemicals called the reactants. The reaction between an acid and a base is called neutralization, and the products formed are water and a salt.
When hydrochloric acid and sodium hydroxide is mixed together, they interact, and result in salt and a release of heat.
The result of the interaction of these two highly aggressive compounds is table salt and water, these resulting compounds are ultimately harmless, and even beneficial, to human beings.
Therefore, NO TOXIC GAS WOULD BE FORMED BY MIXING HYDROCHLORIC ACID WITH SODIUM HYDROXIDE.
Answer:
HBr, CH3C(OH)2 and CH3COOH, Br-
Explanation:
The conjugate acid-base pairs acid reacts with base to form a conjugate acid and conjugate base.
Conjugate acid is formed when a bases receives a proton (H+) and a conjugate base is formed when an acid losses a proton (H+).
From the given equation:
HBr, CH3C(OH)2 and CH3COOH, Br- are conjugate acid-base pair, where HBr is an acid and CH3C(OH)2 is a conjugate acid while CH3COOH and Br- is the conjugate base.
Sucrose has a chemical formula of C12H22O11. The molar mass of all the atoms added up is 342.297 g/mol.
342.297 g/mol * 1/0.105 mol = 3,259.971 g of sucrose. That is about 3.260 kilograms.
Answer:
Here's what I find
Explanation:
You don't use ΔHfus. You use ΔHvap
There are some preliminary calculations:
- Use the density of the liquid to calculate its mass.
- Use the molar mass to calculate the moles (n)
The formula for the heat (q) absorbed during vaporization is
q = nΔHvap
Insert your numbers into the formula, do the calculation, and you have the answer.
