How many grams of Silver Nitrate must be added to the solution to completely react with Sodium Chloride according to the reaction below: NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)

5.81g of AgNO₃ must be added

Explanation:

The solution contains 2.00g of sodium chloride.

Based on the reaction, 1 mole of NaCl reacts per mole of AgNO₃. To solve this question, we need to find the moles of NaCl in 2.00g and, these moles = Moles of AgNO₃ that must be added:

moles NaCl = Moles AgNO₃-Molar mass: 58.44g/mol:

2.00g * (1mol / 58.44g) = 0.0342 moles NaCl = Moles AgNO₃

Mass AgNO₃ -Molar mass: 169.87g/mol-:

0.0342 moles * (169.87g / mol) =

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
