Answer:
E
Explanation:
100 minutes is 5 half lives ( 100 min/20 min/half life)
= (1/2 )^5
1 x 10^20 * (1/2)^5 = 3.125 x10^18 molecules
Answer:
See explanation
Explanation:
9g of water contains : 9g/18 g/mol = 0.5 mole of water
1) 2 moles of hydrogen yields 2 moles of water
x moles of hydrogen yields 0.5 moles of water
x= 2 × 0.5/2 = 0.5 moles of hydrogen
Mass of hydrogen = 0.5 moles × 2 = 1 g of hydrogen
2) Number of moles of Al(OH)3 = 468 g/ 78 g/mol = 6 moles
2 moles of Al(OH)3 yields 3 moles of H2O
6 moles of Al(OH)3 yields 6 × 3/2 = 9 moles of H20
Mass of water =9 moles × 18 g/mol = 162 g of water
3) There are 13 oxygen atoms in the compound.
Mass of each oxygen atom = 16 g
Total mass of oxygen atoms = 13 × 16 = 208 g
Answer:
no because it already had it in there and it exploded by a fuse
