Answer:
False. The balance equation for the redox reaction is:
2Fe + 3CuSO₄ → 3Cu + Fe₂(SO₄)₃
Explanation:
Let's think the half reactions:
Fe → Fe³⁺ + 3e⁻
The Fe increase the oxidation state. This is the oxidation, where Fe changes from 0 to +3
Cu²⁺ + 2e⁻ → Cu
This is the reduction. Cu changes from 2+ to 0
We multiply the half reaction x2 and x3 to balance the electrons
2Fe → 2Fe³⁺ + 6e⁻
3Cu²⁺ + 3e⁻ → 3Cu
And we sum both
2Fe + 3Cu²⁺ + 6e⁻ → 3Cu + 2Fe³⁺ + 6e⁻
The electrons are cancelled, so the balance reaction is:
2Fe + 3CuSO₄ → 3Cu + Fe₂(SO₄)₃
You will need to look up some conversions of gram to lbs
1 gram = 0.00220462262 pounds
1 mL = 0.000264172052 US gallons
and mL to gal
1.035 g / cm^3 x 0.0022 lbs / 1 gram x 1 mL / 0.000264 gal
Answer:
produces carbon dioxide when reacting with carbonates
A
Industry uses only about 18% while the others use around 70-90% of water.
Answer:
He won 32 games.
Explanation:
<em>Another way of expressing 75% is 75/100.</em>
To calculate how many games the baseball pitcher won, we <u>multiply the total of games played</u> (43, in this case) by the percent won:
43 * 75/100 = 32.25 ≅ 32
So the baseball pitcher won 32 games.
