Answer:
mass NH3 = 11.264 g
mass N2 = 9.264 g
Explanation:
balanced reaction:
∴ mass H2 = 2.00 g
∴ molar mass H2 = 2.016 g/mol
∴ molar mass N2 = 28.0134 g/mol
∴ molar mass NH3 = 17.031 g/mol
⇒ mol H2 = (2.00 g)*(mol/2.016 g) = 0.992 mol
⇒ mol NH3 = (0.992 mol H2)*(2 mol NH3/3 mol H2) = 0.6614 mol
⇒ mass NH3 = (0.6614 mol)*(17.031 g/mol) = 11.264 g
⇒ mol N2 = (0.6614 mol NH3)*(mol N2/2 mol NH3) = 0.3307 mol
⇒ mass N2 = (0.3307 mol)*(28.0134 g/mol) = 9.264 g
<span>The standard unit for measuring volume is the B. liter.
Standard units for measuring anything are the most basic units, without any prefixes - so liter, meter, etc. So it's not different here - milliliter and deciliter are incorrect, and cubic centimeter is commonly used for volume, but it is not the standard unit.

the transfer of energy from place to place or particle by direct contact is called conduction
The zebra is

Not moving 20-40
Answer:
The difference between a physical reaction and a chemical reaction is what its made of. In a chemical reaction, there is a change in the materials of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition. Whereas will a chemical change there is not.
