2li +__h₂0= __lioh+h₂
balance the equation

2Li+2H2O=2LiOH+H2

We need to make number of the atoms of each reactant(the elements from the left side)equaled to the products(the elements from the right side)

Li is 2 on the left side so in order to make it balanced we add a 2 in front of LiOH.

For the H2O we take a look at the right side there are 2 atoms from H2 and 2 atoms of H for 2LiOH therefore we have 4 atoms of H in the right side and only 2 in the left side.So,to make them equal we will add a 2 in front of H2O.

Hope,I explained well.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the answer is a. co2, this would be colder than the : )
