Ammonia , nh3, can be made by reacting nitrogen and hydrogen and the equation is n2+3h2--> 2nh3 how many moles of nh3 can be made if 7 moles of h2 reacts with n2

Iwll give extra points to who gets this for ! what type of reaction is this? ?

Ascientist measures the speed of sound in a monatomic gas to be 449 m/s at 20∘c. what is the molar mass of this gas?

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
