Answer:
Explanation:
The mass of the sun is about 1.98 x 10^30 kilograms. The mass of the earth is 5.97x 10^24 kilograms.
1.98 x 10^30 / 5.97x 10^24 = 331658 times greater
Answer:
I believe the answers C: Thermalizing.
Explanation:
Answer is: -267 kJ/mol.
Chemical reaction: Ag₂O(s) + H₂S(g) → Ag₂S(s) + H₂O<span>(l).
</span>ΔHrxn = ∑ΔH(products of reaction) - ∑ΔH(reactants).
ΔHrxn = (ΔHf(Ag₂S) + ΔHf(H₂O)) - (ΔHf(H₂S) + ΔHf(Ag₂O)).
ΔHrxn = (-32,6 kJ/mol - 286 kJ/mol) - (-20,6 kJ/mol - 31 kJ/mol).
ΔHrxn = -318,6 kJ/mol + 51,6 kJ/mol.
ΔHrxn = -267 kJ/mol.
Galileo said that the Sun revolved around the Earth, and that the Earth was the center of the universe ! (:
