Answer:
0.667
Explanation:
divide the mass value by 1000
Answer:
31 electrons.
Explanation:
Atoms initially have a neutral charge. So if this atom were neutral, it would have 29 electrons to balance out with the 29 protons. Protons are never added or removed. Since this atom has a -2 charge, that means it is an anion with 2 additional electrons. 29e- + 2e- = 31e-
Ba(OH)2 Ba-2 power + 2 OH H2 + SO 4
All numbers are exponents.
4
Explanation:
The number 4 in the hydrologic cycle depicts surface runoff.
The hydrologic cycle depicts the cyclic movement of water between different earth components.
It shows water in all its phases.
- From the attached image, runoff is depicted 4.
- Runoff is water that moves on the surface after precipitation.
- Number 1 is evaporation where water changes to vapor.
- Number 2 is condensation where the vapor cools back to liquid.
- Number 3 is precipitation where the liquid water is forced down under gravity.
- On the surface, the water runs as runoff.
