Chemistry
1 answer:
Firdavs [7]4 years ago
4 0

Answer:

Option B. HgCl2

Explanation:

Data obtained from the question include:

Mass of Mercury (Hg) = 47.3g

Mass of chlorine (Cl) = 16.7g

The empirical formula for the compound can be achieved by doing the following:

Step 1:

Divide by their individual molar mass

Hg = 47.3/201 = 0.235

Cl = 16.7/35.5 = 0.470

Step 2:

Divide by the smallest to express in whole number:

Hg = 0.235/0.235 = 1

Cl = 0.470/0.235 = 2

Therefore, the empirical formula is HgCl2

For each of the following acid-base reactions, calculate how many grams of each acid are necessary to completely react with and
Anika [276]

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.
