Answer:
The entropy change of carbon dioxide = 0.719 kJ/k
Explanation:
Given:
1.5 m - 3 insulated rigid tank contains 2.7 kg of carbon dioxide at 100 kPa
The objective is to determine the entropy change of carbon dioxide
Formula used:
ΔS=
Solution:
On considering,
ΔS=
On substituting the values,
ΔS=
ΔS=0.719 kJ/k
Answer:
Option (C) 1 × 10^−12
Explanation:
Step 1:
Data obtained from the question include:
[H+] = 1x10^−2
[OH−] =?
Step 2:
Determination of [OH−] . This is illustrated below:
[H+] x [OH−] = 1x10^-14
1x10^−2 x [OH−] = 1x10^-14
Divide both side by 1x10^−2
[OH−] = 1x10^-14 / 1x10^−2
[OH−] = 1x10^-12
Therefore, the [OH−] of the solution is 1x10^-12
Answer:
Ice is the last major agent of weathering, erosion, and deposition.
Explanation:
Water often seeps into the cracks in rocks. When the temperature drops, the water in the cracks freeze and expand, causing the crack to widen. Eventually, the rock is broken into smaller pieces.
"A" is the answer. The chemical reaction is when the batter becomes brown.
B is mixing C is mass becoming a liquid and D. is dissolving no chemical reaction happened there.
