Explanation:
In this reaction, the reactants are Li and N2. The product is Li3N
So we have;
Li + N2 → Li3N
Upon balancing, we have;
6Li + N2 → 2 Li3N
The sum of the coefficients is 6 + 1 + 2 = 9
What is the question you need answered
Correct answer: Galvanic cell
Reason:
Following are the differences between Galvanic cell and electrolytic cell:
1. <span>Galvanic cell converts chemical energy into electrical energy , on other hand <span>electrolytic cell converts electrical energy into chemical energy.
2. In galvanic cell, </span></span><span>redox reaction is spontaneous and is responsible for the production of electrical energy. in electrolytic cell, t<span>he redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
Thus, galvanic cell </span></span><span>refers to an electrochemical cell that produces an electric current</span>
The balanced chemical reaction is:
<span>C4H8O2 + 2H2--> 2C2H6O
</span>A. How many grams of ethyl alcohol are produced by reaction of 2.7 mol of ethyl acetate with H2? 2.7 mol C4H8O2 ( 2 mol C2H6O / 1 mol C4H8O2) (46.07 g / 1 mol) = 248.78 g ethyl alcohol
B. How many grams of ethyl alcohol are produced by reaction of 13.0g of ethyl acetate with H2?
13.0 g C4H8O2 ( 1 mol / 88.11 g) ( 2 mol C2H6O / 1 mol C4H8O2) (<span>46.07 g / 1 mol) = 13.59 g ethyl alcohol</span>
C. How many grams of H2 are needed to react with 13.0g of ethyl acetate?
13.0 g C4H8O2 ( 1 mol / 88.11 g) ( 2 mol H2 / 1 mol C4H8O2) (2.02 g / 1 mol) = 0.5961 g H2
