Answer: The reaction produces 2.93 g H₂.
M_r: 133.34 2.016
2Al + 6HCl → 2AlCl₃ + 3H₂
Moles of AlCl₃ = 129 g AlCl₃ × (1 mol AlCl₃/133.34 g AlCl₃) = 0.9675 mol AlCl₃
Moles of H₂ = 0.9675 mol AlCl₃ × (3 mol H₂/2 mol AlCl₃) = 1.451 mol H₂
Mass of H₂ = 1.451 mol H₂ × (2.016 g H₂/1 mol H₂) = 2.93 g H₂
Explanation:
It is the chlorophyll/chloroplast. The chlorophyll is the color
Answer:
They are very similar because they both are very important for the sustenance of the cell. Both also help to provide energy for the cell, Chloroplasts can make its own food through photosynthesis and the mitochondria helps to break down the energy.
