Answer:
Bari oxit được tạo nên từ các nguyên tố Bari (Ba) và Oxi (O)
Explanation:
Burning Mg in the air and reacting with O2 forming a white powder of MnO
So the equation is going to be:
Mn + O2 ⇒ MnO (this equation is not conserved)
to make it equilibrium:
1- First we should put 2Mno to equal the O2 on both sides.
So it will be:
Mg + O2⇒ 2MgO
2- Second we should put 2Mn to equal the Mn on both sides.
2Mg + O2⇒ 2MgO (this equation is conserved)
After putting the physical states the final equilibrium equation is going to be:
Δ
2Mg(s) + O2(g)⇒ 2MgO(s)
exactly 22.0 grams
because freezing is a physical change not a chemicl change..so nothing is taken away or added
The amount of sediments being carried has been increasing rapidly. There is no certain amount of number
