Answer:
5 atoms of hydrogen will be found in the products
Explanation:
5 atoms of hydrogen will be found in the products becuase the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
Answer:
increases as you move down a group as the number of electrons increases. Therefore, the atomic radius increases as the group and energy levels increase
Explanation:
The mass isnt relevant
520 - 120 = 400
400 / 8 = 50
50ms^-2
Answer:
4. 15
Explanation:
The given formula is:- 
1 mole of the salt contains 2 moles of nitrogen atom, 8 moles of hydrogen, 1 mole of sulfur and 4 moles of oxygen atom as can be seen from the formula.
Thus,
1 mole of salt contains total of 15 moles of the atoms which constitute the salt.
<u>Hence, 4. is the answer.</u>
