Varvara68 [4.7K]
The answer is: 197 grams

Why?

All 20 grams of aluminum was used to form aluminum bromide. Only 177 grams of bromide were used to make aluminum bromide, since 23 grams were left over.

20 grams + 177 grams = 197 grams, so the answer is 197 grams.

How many major reservoirs does carbon move between?<br> A. 3<br> B. 4<br> C. 5<br> D. 2
Irina-Kira [14]
<span>Carbon can also bond with other four atoms because of its outer shell (valence shell) that has four electrons. This is the reason why organic molecules can be so large because of this bonding. Suppose you have a compound of CCl4. You know that chlorine can only share 1 electron because 7 of its electrons are filled. Also, in carbon, it can only share 4 electrons because 4 of it are already filled. That is why carbon needs four chlorine to form CCl4. The answer is letter <u>B.</u></span>
