Explanation:
Let us proceed with a reaction
A(aq)+B(aq) C(aq) + D(g)
Taking A, B and C are in aqueous solution. D being a gas. The reaction is carried out in a close vessel. As reaction proceeds, A and B react to give C and D. As the concentration of C and D increases, they react to give back A and B. Now suppose the reaction is carried out in a open vessel so that the gas D can escape in the atmosphere. So the gas D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Let us take another example.
A(aq)+B(aq) C(aq) + D(aq)
Here, D is a volatile liquid. As soon as D is formed, it is removed by distillation. So D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Answer:
No because it's located inside the nucleus of the atom
hope this helps
have a good day :)
Explanation:
Answer:
3.2 cm X 2.8 cm X 2.6 cm/ 1 cube - not exact
1 mL - exact
1 cm³ - exact
12 cubes/ 1 tray - exact
268.8 mL/tray - not exact
Explanation:
We can use the picture attached below to solve this problem. The first part is not exact because Sally is using a ruler to measure the cube which would have a margin of error, regardless of how small. The is exact, since that is the actual accurate exchange. Next, since there are 12 cubes in a single ice tray this measurement is also exact. Lastly, since Sally's initial measurement of the cubes is not exact, then the final calculated value will also not be exact.
