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) =

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
