Answer: Understanding oxidation-reduction reactions
Explanation:
Rusting occurs when electrons are exchanged between iron and oxygen.
Answer:
267.14 iron oxide.
Explanation:
Given that
We know that molecular mass of iron-oxide = 160 g/mole.
We know that molecular mass of iron = 56 g/mole.
From the above reaction we can say that
1 mole of iron -oxide produce 2 mole of iron
160 gm of iron oxide produce 112 gm of iron
So
1 gm of iron required of iron oxide
Therefore
187 gm of iron required of iron oxide.
Therefore 187 gm of iron required 267.14 iron oxide.
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms</span>
