The number of the valence electrons determines the oxidation state i.e. oxidation number e.g. oxygen has 6 valence electrons the oxidation number is -2 that its need to fill up an octet structure.
Answer:
14.4 covers/hr.
Explanation:
First, we need to identify how much covers are produced in 1 hour, which will be total produced divided by the total time:
covers/hr = 120/10
covers/hr = 12
If the production will be increased by 20%, it means that new production will be the initial one plus 20% (0.20) of it:
12 + 0.20*12 = 14.4 covers/hr.
1. C. Potassium and Iodine
2. A. Solid
M₁ x V₁ = M₂ x V₂
2.5 x V₁ = 0.50 x 100.0
2.5 x V₁= 50
V₁ = 50 / 2.5
V₁= 20 mL
hope this helps!
