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) =

5.81g of AgNO₃ must be added

Standing in the sunlight and feeling the heat on your face (uv radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues)orstanding near a fire and feeling the heat on your skin (infrared radiation transfer)

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
