Explanation:
Moles of N2 = 35.0g / (28g/mol) = 1.25mol
Moles of H2 = 60.0g / (2g/mol) = 30.0mol
Since 1.25mol * 3 < 30.0mol, nitrogen is limiting.
Moles of NH3 = 1.25mol * 2 = 2.50mol.
Mass of NH3 = 2.50mol * (17g/mol) = 42.5g.
30.0mol - 1.25mol * 3 = 26.25mol.
Excess mass of H2
= 26.25mol * (2g/mol) = 52.5g.
Do elements in a group on the periodic table have similar chemical properties because their atoms have the same number of electrons
A. same number of outermost electrons
When an ice cube melts, it's still H20. there is no bonding with any other molecules. the molecules of H20 simply spread out. Ice melting is thus a physical reaction, not a chemical one.
The plants would over populate and the predetors would become extinct
