Answer:
1. cells
2. energy
3. pre-existing cells by division
Explanation:
Magnesium element exists as single atoms. Free oxygen is always diatomic (two atoms bonded together) as O2. Nitrogen gas is also diatomic N2.
2Mg + O2 → MgO
Mg forms a +2 ion, O forms a -2 ion, so they combine and balance in a 1:1 ratio. MgO, magnesium oxide, is a solid.
3Mg + N2→Mg3N2
Mg forms a +2 ion, but N forms a -3 ion. Hence the Mg3N2 configuration for magnesium nitride.
Lets write the formula, then start to determine!
Force = mass times acceleration
Therefore,
acceleration = force divided by mass
Answer:- A) mass
Answer:
The condensation of water occurs in Atmosphere.
Explanation:
As we know when water is heated it converts into vapors and vapors on cooling condense back into liquid water. Hence, the water present in Oceans (hydrosphere) on heating evaporates (remember evaporation takes place at any temperature) and move upward into the atmosphere. In atmosphere at high altitude the temperature drops (almost 18 °C) which causes the water vapors to condense hence, resulting in the formation of clouds which on precipitation causes rain fall.
