I need to know what the correctly balanced chemical equation is for: Heating Magnesium hydroxide(Mg(OH)2)?

Question

and
Mg + N2 -->

Answer 1

Normally when a metal hydroxide is heated to very high temperatues (>300 deg C) it will extrude water vapor to produce an oxide. You should get: Mg(OH)2 --> MgO(s) + H2O (g)

Magnesium will not react with nitrogen gas.

Answer 2

to illustrate: stability this chemical equation. ok + H2O = KOH + H2 it would actual help in case you will possibly first count variety the cost of their ions first. in the 1st chemical equation wherein ok + H2O ok and O in basic terms have a million ion through fact there at the instant are not any numbers in the amazing facet which understood to be a million on a similar time as H has 2 ions through fact of that 2 beside it. So ok = a million O = a million H = 2 in the 2d chemical equation that's KOH + H2 ok = a million O = a million H = 3 H has 3 ions through fact that there are 2 Hydrogen in this equation the different hydrogen has a million ion and the different has 2, so a million + 2 = 3 observe: There at the instant are not any minus in a chemical equation in basic terms plus. Now which you recognize the ions. it's time to stability them. ok + H2O = KOH + H2 you're able to try this by utilising trial and blunder, it would take the time yet once you will in basic terms attempt and attempt you will get it. attempt to visual reveal unit the two equation. in the equation on the left ok = a million. in the amazing ok = a million so this element is already stability. The O in the left has a million ion and in the amazing it additionally has a million ion so it somewhat is stability additionally. enable's see H in the left equation H = 2 on a similar time as in the amazing H = 3 it somewhat is not stability which you would be able to stability it you need to positioned some numbers in beggining of a chemical style to make it stability. in this equation to make it stability the equation ought to be like this. 2 ok + 2 H20 = 2 KOH + H2 through fact that H isn't stability we positioned a 2 in KOH so as that the H in there'll substitute into 2. 2(a million)=2 a million=ion of H so as which will make H substitute into 2 ions ands so through fact the different factors ok and O. I positioned yet another 2 in H2O so as that the O will substitute into 2 additionally. And yet another 2 in ok to make it 2 aswell. in 2 ok +2 H2O ok = 2 H = 4 through fact 2 elevated by utilising the ion that's 2 is 4. O = 2 in 2 KOH + H2 ok = 2 H = 4 through fact 2(a million) + 2 = 4 O = 2 So now they're balanced.

Answer 3

Mg (OH)2(s) -> MgO(s) + H2O(g) At the temperature of the reaction water leaves as a gas.

3Mg(s) + N2(g) -> Mg3N2(s)

Answer 4

you wrote, heating magnesium hydroxide, so the input is Mg(OH)2. (if I understood your clearly)

2Mg(OH)2 (s)+ O2 (g)--> 2Mg (s) + 2H2O (g)

so no nitrogen at the left side of the formula

(s) = solid, (g) = gas

Answer 5

ok
