Chemistry
1 answer:
Allisa [31]3 years ago
6 0

Answer:

28,125 g

Explanation:

m(O₂) = 100 g

n(O₂) =M(O₂)/m(O₂)=32 gram per mole / 100 g = 0,32 mole

O₂ + 2H₂ ⇒ 2H₂O  ,  n(H₂O) = 2 × n(O₂)

m(H₂O) = M(H₂O)/2 × n(O₂) = 18 grams per mole / 2 × 0,32 mole = 28,125 g

Aluminum has a face-centered cubic unit cell. How many atoms of Al are present in each unit cell
Serjik [45]

Answer:4

Explanation:

As shown in the image attached, a face-centred cubic structure has 8 atoms at the corners and 6 face center atoms.

Each corner atom contributes to eight cell, so per unit cell 1/8 ×8 =1atom

Face center atoms contributes to two unit cells 1/2 × 6=3atoms

Total atoms =3+1=4atoms

Therefore the atoms in Al FCC per unit cell is 4

Answer:

2 half-lives=0.8

6 half-lives= 0.05

Explanation

Half-lives are constant and always decrease by half, implying that the concentration decreases by half at a consistent rate.

3.2/2= 1.6/2= 0.8 is two half-lives

3.2/2= 1.6/2= 0.8/2= 0.4/2= 0.2/2= 0.1/2=0.05 is six half-lives
