A ball held at 3 meters. Option B.
Answer:

Explanation:
Hello,
In this case, the relationship between the mass, heat, temperature and heat capacity id given by:

In such a way, the temperature change results:

Clearly it is a positive change which means the temperature increases as heat is added.

Answer:
0.316 moles are produced.
Explanation:
We state the redox reaction:
4HNO₃ + Cu → Cu(NO₃)₂ + 2NO₂ + 2H₂O
We need to determine the limting reactant:
0.1 L . 14 M = 1.4 moles
10 g . 1mol/ 63.54g =0.158 mol
Cu is the limiting reactant. Let's see
4 moles of acid need 1 mol of Cu to react
1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles
We do not have enough Cu.
1 mol of Cu can produce 1 mol of NO₂
Then 0.158 moles will produce, 0.316 moles. (double of moles)
If we see stoichiometry, ratio is 1:2
Answer: 2.4 M
Explanation:
According to the neutralization law,

where,
= molarity of
solution = 3.5 M
= volume of
solution = 34.3 ml
= molarity of
solution = ?
= volume of
solution = 50 ml
= valency of
= 1
= valency of
= 1


Therefore, the concentration of NaOH solution is 2.4 M.
