Answer: Ag:  2.79x10^22 atoms

              C atoms:  6.02x10^23 C atoms

Explanation:

5.0 grams of Ag is 0.0464 moles of Ag.  (0.0464 moles)*(6.02x10^23 atoms/mole) = 2.79x10^22 atoms Ag

(0.50 moles)*(6.02x10^23 molecules/mole)*(2 C atoms/molecule) = 6.02x10^23 atoms of C

How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Dahasolnce [82]
If the enthalpy change is negative, then the reaction is exothermic because heat energy was lost to the surroundings.

If the enthalpy change was positive, then the reaction was endothermic because heat energy was gained from the surroundings!

A sample of a gas at 25°C has a volume of 150 mL when its pressure is 0.947 atm. What will the temperature of the gas be at a pr
dezoksy [38]

Answer:

25°C

Explanation:

Combined Gas Law (P₁V₁)/T₁ = (P₂V₂)/T₂

(0.947 atm)(150 mL)/25°C = (0.987 atm)(144mL)/T₂

5.682 = 142.128/T₂

T₂ = 142.128/5.682

T₂ = 25.0137272756°C = 25°C
