Answer:
Its helium
Explanation: Because teh effective nuclear charge holds the valence ectrons clos to the nuclues. the Atomic radius would decrease as you move from the led=ft and right of the perodic table
Answer: yes they do.
Explanation:
I'm tryna get more points because my other account got blocked for the next 48 hours.

Answer:
2NO(g) + O2(g) --> 2NO2(g)
now 400 ml of NO × 2 mol of NO2/2 mol of NO
= 400 ml of NO2
now 500 ml of O2 × 2 mol of NO2/1 mol of O2
= 1000 ml of NO2
now 400 ml of NO2 × 1 mol of O2/2 mol of NO
= 200 ml
subtract that from 500 ml of total i.e. 500-200 =300 ml
The total volume of the reaction mixture is 1000 ml -300ml = 700 ml
Answer:
The process describes the source of energy of the Sun such that it shines as a result of nuclear fusion of hydrogen taking place.
Explanation:
The Sun generates energy by hydrogen within the Sun undergoing nuclear fusion to form helium.
Nuclear fusion reaction involves combining of two or more atomic nuclei to produce one or more completely different atomic nuclei as well as protons or neutrons, with a loss or gain of mass and the release or absorption of energy.
The process whereby four hydrogen atoms combine to form one helium atom with a mass deficit, which is accounted for by the release of energy, result in the high intense light of the Sun.
