<span> B. produces as much energy as cell respiration. i am pretty sure that is the answer</span>
Answer:
Number of moles = 2.8 mol
Explanation:
Given data:
Number of moles of water = ?
Volume of water = 50 mL
Density of water = 1.00 g/cm³
Solution:
1 cm³ = 1 mL
Density = mass/ volume
1.00 g/mL = mass/ 50 mL
Mass = 1.00 g/mL× 50 mL
Mass = 50 g
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 50 g / 18 g/mol
Number of moles = 2.8 mol
Answer:
Fluorine gas reacts with water.
the balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ --> 2NH₃
stoichiometry of H₂ to NH₃ is 3:2
in gases number of moles of gas is directly proportional to volume of gases.
therefore molar ratio is equal to volume ratios.
this means volume ratio of H₂ to NH₃ is 3:2
volume of H₂ reacted - 54.1 L
if 3 L of H₂ forms - 2 L of NH₃
then 54.1 L of H₂ forms - 2/3 x 54.1 = 36.1 L of NH₃
volume of NH₃ formed is 36.1 L
Answer: 0 neutrons
Explanation:
to find neutrons you subtract the atomic number from the Atomic mass. The atomic mass is 1. The atomic number is 1. So 1-1=0 making the neutrons in a hydrogen molecule 0.
