How many moles of Na are needed to produce 4 moles of NaCl in the

reaction below?

2 Na + Cl2 --> 2 Naci

Select one:

4 moles of Na are needed to produce 4 moles of NaCl

Explanation:

The balanced chemical equation is :

According to stoichiometry :

2 moles of are formed from = 2 moles of

Thus 4 moles of will be formed from =  of

Thus 4 moles of Na are needed to produce 4 moles of NaCl

sure what is it? ^w^

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
