What are the coefficients for the reaction _cl2o5 + _h2o → _hclo3 once it is balanced?
a)1, 1, 1
b)1, 1, 2
c)1, 2, 2
d)2, 1, 1

The correct option is B.

Explanation: We are given an unbalanced chemical equation, so to find out the actual coefficients for the reaction, we need to balance it.

Balancing a chemical equation, we get

The coefficients for the reaction as seen from above equation are 1, 1, 2.

The correct option is B.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
