Answer:

m_{HCl}=2.19gHCl

Explanation:

Hello,

In this case, for the reaction between hydrochloric acid and sodium hydroxide, for 2.4 g of base, we can compute the neutralized grams of acid by applying the 1:1 molar ratio between them and their molar masses, 36.45 g/mol and 40 g/mol respectively as shown below by stoichiometry:

m_{HCl}=2.4gNaOH*\frac{1molNaOH}{40gNaOH}*\frac{1molHCl}{1molNaOH}*\frac{36.45gHCl}{1molHCl}\\   \\m_{HCl}=2.19gHCl

Best regards.

Which of the following reactions Shows a chemical change producing a gas? APEX
Nina [5.8K]

Answer:2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)

Explanation: A chemical change is a reaction in which chemical composition of the substance changes. Some bonds are broken and some new bonds are formed.

The reactants are written in terms of their chemical formula on the left hand side and the products are written in terms of their chemical formula on right hand side with a arrow in between. The chemical symbols are followed by their physical states such as (l) for liquid, (s) for solid, (g) for gas and (aq) for aqueous.

Thus the only reaction producing a gas is 2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)
