Please help me on this one. Thanks

Option B

Explanation:

Look here,

2H2 + O2. --> 2H2O

On,

LHS = 2 × H2 = 4H atoms and 2O atoms

RHS = 2 × H2 = 4H atoms and 2 × O = 2O atoms

Hence,

LHS = RHS and above equation is balanced.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
