The jar has 138 grams of zinc.
<u>Solution:</u>
Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.
A jar of the chemical contains 736 grams of copper.
We have to find how many grams of zinc does it contain
Let "n" be the grams of zinc needed for 736 grams of copper
Now, we know that,
16 grams of copper ⇒ 3 grams of zinc
Then, 736 grams of copper ⇒ n grams of zinc
So, by criss cross multiplication,
16n = 3 x 736
16n = 2208
n = 138
Hence, the jar has 138 grams of zinc.

Answer:
-i
Step-by-step explanation:
i^15
Divide the exponent by 4
15/4 = 3 r 3
Take the remainder and use as the exponent
i^3
We know that i^2 = -1
i^3 = i^2 *i
i^3 = -1*i
-i
