Answer:
3.08 g of Oxygen .
Explanation:
2Mg + O₂ = 2MgO
2 mole 1 mole
molecular weight of Mg = 24
2 mol of Mg = 48 g
48 g of Mg reacts with 32 g of oxygen
4.62 g of Mg will reacts with 3.08 g of Oxygen .
To determine the proper number of significant figures of a liquid using a graduated cylinder you have to precisely count or measure the indicated number on the cylinder.
Each compound will be neutral
No of atoms = 6Ca + 4(1P + 4O)] = 6 atoms + 4x5 atoms = 6 atoms + 20 atoms
= 26 atoms
They will continue moving because an object in motion will stay in motion until acted upon by a new force. I believe this is Newton's Law of Motion.
