Answer: 66
Explanation: To find the mass number you would have to add the number of protons and the number of neutrons.
Answer:
They all contain switches
I think the answer would be trenches but I’m sorry if I’m wrong
Given reactions:
(A) 6CO2(g) + 6H2O(l) + sunlight → C6H12O6(aq) + 6O2(g)
(B) 2H2(g) + O2(g) → 2H2O(g) + energy
Exothermic reactions are those which proceed with the release of heat/energy. In contrast, endothermic reactions proceed with the absorption of energy in the form of heat or light.
Since reaction A required sunlight, it is endothermic. Reaction B releases energy, hence exothermic
Ans: (B)
A is endothermic
B is exothermic
Answer:
B
Explanation:
Step 1 occurs at a slower rate than Step 2.
