Answer: m = 50 g ZnSO4
Explanation: First is convert the moles of Zn to the moles of ZnSO4 by having their mole ratio which is 2:2 based from the balanced equation. Next is convert the moles of ZnSO4 to mass using its molar mass.
0.311 mole Zn x 2 moles ZnSO4 / 2 moles Zn
= 0.311 moles ZnSO4
0.311 moles ZnSO4 x 161 g ZnSO4 / 1 mole ZnSO4
= 50 ZnSO4
Answer:
This description needs a unit describing the system of measurement.
Answer:
Electron cloud
Explanation:
The electron cloud is an informal term in chemistry and physics. This region describes the negatively charged electrons in their orbit surrounding the nucleus in an atom. The nucleus has protons in it that have a positive charge on it. It is not easy to know where exactly an electron in any specific time but the electron cloud helps to know electron is moving in this specific area.
Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
<h3>What is change of state?</h3>
Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.
In the graph shown above, water exists in three states at different points.
- Water exists as a solid at A
- Water exists as a liquid at B
- Water exists as a gas at C.
Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
