The answer is: endothermic reaction.
This reaction is endothermic (enthalpy is higher than zero), which means that heat is added.
According to Le Chatelier's principle when the reaction is endothermic heat is included as a reactant and when the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the right, producing more products.
Answer: -
0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution
Explanation: -
Strength of NaCl = 2.0 M
Volume of NaCl solution = 100.0 mL
=
= 0.1 L
Number of moles of NaCl = volume of NaCl x Strength of NaCl
= 0.1 L x 2.0 M
= 0.2 moles
0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution

Explanation:
Answer: molecules
Explanation:
To calculate the moles, we use the equation:
For
Given mass= 165 g
Molar mass of = 44 g/mol
Putting values in above equation, we get:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
1 mole of contains = molecules of
Thus 3.75 moles contains = molecules of
Thus there will be molecules of
The molar mass of CO2 is 44 grams per mole.
165 grams / 44 grams per mole of CO2 = 3.75 moles CO2
Using Avogadro’s law where 1 mole of substance equals 6.023 x 10^23 molecules
3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2
