Given the reaction: Ca + 2H,0→ Ca(OH)) + H2
How many moles of H, O are needed to exactly react with
2.0 moles of Ca

4

Explanation:

because use the molar ratio of

ca:h2o

1:2

2;4

so u times it by 2 .

hope this helps:)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
