So we're told that magnesium metal and oxygen gas combine to form magnesium oxide.
00:08
So let's just go ahead and write these things out in words.
00:11
And we can go ahead and start making our word equation.
00:20
So over here, we've got the reactants, magnesium and oxygen.
00:24
So let's go ahead and combine them with the plus sign.
00:28
Over here, we've got magnesium oxide, which is the product.
00:31
So we need to have the arrow to show that we're switching over to the product side of the equation.
00:36
And here we've got our word equation.
00:39
Pretty simple.
00:40
Now let's go ahead and write the unbalanced formula equation.
00:45
So we can convert the magnesium to its elemental symbol, which is mg.
00:50
And magnesium metal is a solid.
00:54
Oxygen is represented on the periodic table by an o.
00:58
And we're told us the gas, so obviously we need to write the g...
