Question

Subscripts and coefficients are used to balance chemical equations so that the same number of atoms appear on each side of a chemical equation. true or false

Answer 1

What do you think?

Answer 2

If I gave you the chemical equation:
\[2H+O \rightarrow 2H_2O\]
How would you balance that?

Answer 3

Add 2 more oxygen

Answer 4

one more sorry

Answer 5

No quite. Because on the right we see for every 1 Hydrogen there is actually 2 then we have 2 times 2 = 4 Hydrogen and 2 oxygens. Do you see that?

Answer 6

So we must actually multiply the left side by 2 to get 4 hydrogens and 2 oxygens

Answer 7

yes :)
