It'd be a physical change. This is because it's a change in the state of matter and not altering the chemical structure of water
The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.
<h3>What is pH?</h3>
The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.
The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.
Therefore, the compound with a pH of 13.3 is basic.

Answer:
18.06 g of ammonia
Explanation:
This is the reaction:
NH₃ + CH₃OH → CH₃NH₂ + H₂O
Ratio is 1:1
1 mol of ammonia reacts with 1 mol of methanol.
Let's convert the mass of methanol to moles.
34 g . 1 mol / 32 g = 1.06 moles
We need 1.06 moles of NH₃ whichs is the same to say:
1.06 moles. 17 g / 1 mol = 18.06 g of NH₃
Answer:-
500324 grams
Explanation:-
Heat absorbed Q = M x Cp x T
We are given T = 10 [ The maximum allowed temperature increase]
Plugging in the values
6.70 x 10^ 6 J = M x 30.8 J / (K mol) x 10 K
M = 6.70 x 10 ^6 / (30.8 x 10)
= 21753 moles
Atomic Mass of sodium =23 gram / mol
Grams of liquid sodium required = 21753 moles x 23 grams / mol
= 500324 grams
The Yellow River is the most important water resource for the dry north of China, playing an irreplaceable role in economic development, and agriculture. Since 1960 over 14 dams have been constructed on the river for hydroelectric power, which is vital to northern China's infrastructure.
