<h3><u>Answer</u>;</h3>
pH = 3.03
<h3><u>Explanation</u>;</h3>
NaCl is a neutral salt and does not affect the pH.
moles HCl = g HCl / MM
= 16.5 / 36.5
= 0.452 equivalent to moles H+
Molarity H+ = moles H+ / L
= 0.452 / 482
= 0.000938 M
Hence; pH = -log[H+]
= -log(0.000938)
= 3.03
Answer:
A) fission
Explanation:
Fission reactions require a critical mass. The critical mass is necessary because it makes a fission reaction self sustaining. This critical mass is the minimum amount of material required. Nuclear fission additionally depends on the composition, purity and concentration of the fissile material. Critical mass is important in the design of nuclear warheads.
The solution which has the lower freezing point is 20.0 g of H₂O in 1.00 kg of CH₃OH

Does methanol keep things from freezing?</h3>
Methanol is an extremely effective anti-freeze agent. Even little amounts can have a significant effect on freezing temperatures. Deschamps, Mousis, Sanchez-Valle, and Lunine investigated the impact of methanol concentrations of a few percent and discovered that they might play a major role in the formation and preservation of a subsurface ocean.
The effects of pressure on pure ice and pure methanol have been widely researched, but the behaviour of water-methanol mixes has not been as thoroughly explored. We intend to conduct a series of experiments to investigate how various spots on the methanol-water phase diagram change under pressure
