Question

Which equations are balanced?
a.mg (s) + 2hcl (aq) → mgcl2 (aq) + h2 (g)
b.3al (s) + 3 br2 (l) → al2br3 (s)
c.2hgo (s) → 2 hg (l) + o2 (g) which equations are balanced?
a.mg (s) + 2hcl (aq) → mgcl2 (aq) + h2 (g)
b.3al (s) + 3 br2 (l) → al2br3 (s)
c.2hgo (s) → 2 hg (l) + o2 (g) equations "a" and "c" are balanced. only equation "c" is balanced. equations "b" and "c" are balanced. all of them are balanced?

Answer 1

Equations “a” and “c” are the only one that are balanced.
