Answer:

2 Fe + 3 Br₂ → 2 FeBr₃

Explanation:

There are 2 Br atoms on the left, and 3 on the right.  So put a 3 in front of Br₂, and a 2 in front of FeBr₃.

_Fe + 3 Br₂ → 2 FeBr₃

Now there's 6 Br atoms on each side.  There are 2 Fe atoms on the right side, so put a 2 in front of Fe:

2 Fe + 3 Br₂ → 2 FeBr₃

Now the equation is balanced.

Why is force not on a scalar quantity??
snow_lady [41]
Because force always has a direction, it always works towards or against something.


you might know that force,
is rate of change of momentum i.e

force = m (v-u)/t
= (mv - mu )/ t


as we know momentum is a vector quantity so, the rate of change of momentum i.e Force would also be a vector quantity.




momentum = mass × velocity

velocity has a direction so,
momentum has also got a direction.
so, momentum is also a vector quantity.
