what is the balanced chemical equation for the addition of water to the burnt magnesium ribbon?

Answer 1

A burnt magesium ribbon produces MgO. When you add water, this is converted to Mg(OH)2.

So: MgO + H2O = Mg(OH)2.

It is already balanced.

Answer 2

as an occasion: stability this chemical equation. ok + H2O = KOH + H2 it may incredibly help in case you are able to first count style the cost of their ions first. in the 1st chemical equation wherein ok + H2O ok and O purely have a million ion because of the fact there are not any numbers in the main extraordinary factor which understood to be a million on an identical time as H has 2 ions because of the fact of that 2 beside it. So ok = a million O = a million H = 2 in the 2nd chemical equation that's KOH + H2 ok = a million O = a million H = 3 H has 3 ions considering there are 2 Hydrogen in this equation the different hydrogen has a million ion and the different has 2, so a million + 2 = 3 word: There are not any minus in a chemical equation purely plus. Now which you already know the ions. it incredibly is time to stability them. ok + H2O = KOH + H2 you're able to try this via trial and mistake, it may take a while yet once you will purely attempt and attempt you will get it. attempt to observe the two equation. in the equation on the left ok = a million. in the main extraordinary ok = a million so this ingredient is already stability. The O in the left has a million ion and in the main extraordinary it additionally has a million ion so it incredibly is stability additionally. enable's see H in the left equation H = 2 on an identical time as in the main extraordinary H = 3 it is not stability in an attempt to stability it you are able to desire to placed some numbers in beggining of a chemical sort to make it stability. in this equation to make it stability the equation could desire to be like this. 2 ok + 2 H20 = 2 KOH + H2 considering H isn't stability we placed a 2 in KOH so as that the H in there'll replace into 2. 2(a million)=2 a million=ion of H so as which will make H replace into 2 ions ands so because of the fact the different components ok and O. I placed yet another 2 in H2O so as that the O will replace into 2 additionally. And yet another 2 in okay to make it 2 aswell. in 2 ok +2 H2O ok = 2 H = 4 because of the fact 2 more advantageous via the ion that's 2 is 4. O = 2 in 2 KOH + H2 ok = 2 H = 4 because of the fact 2(a million) + 2 = 4 O = 2 So now they are balanced.
