Easy you can't touch the subscripts so u need to add coiffents like a puzzle if you do this then it will chance this 1st name each element on each side then say how much it's worth then see what you need to chance like this
Ti=1
Cl=4
Mg=1.
On the other side
Ti=1
Mg=1
Cl=2. What do you need to change using coffients
Answer:
People, especially kids, tend to think that when water evaporates it just disappears, or turns into the air. But we know based on the law of conservation of mass that any time water changes state it keeps the same mass!
Similarly, when water vapor turns to water droplets, when it goes from its gas to its liquid state, it still has the same mass. It's just in a different phase. This is a perfect example of conservation in mass!
3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
Hope this helps!!
There are 6 molecules of Mg3(PO4)2
6 × 3 = 18 Mg
6 × 4 × 2 = 48 O
