The temperature of 15 grams of water is increased by 3.0 Celsius degrees. How much heat was absorbed by the water? (specific heat of water: 4.18 J/g deg C)

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

i wish i could but this one is weird give me abc and i can solve it.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

answer///carbon;
