A chemistry student needs of 65 gr acetyl bromide for an experiment. She has available 20 g of 38.1 % a w/w solution of acetyl bromide in diethyl ether. Calculate the mass of solution the student should use.

This is an incomplete question, here is a complete question.

A chemistry student needs 65.0g acetyl bromide for an experiment. He has available 20.0 g of a 38.1 % w/w solution of acetyl bromide in diethyl ether. Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button.

Answer : The correct answer is "No solution".

Explanation :

As we are given that 38.1 % w/w solution of heptane in chloroform. That means 38.1 gram of heptane present in 100 gram of solution.

Now we have to determine the mass of solution for 65.0 grams of hepatne.

As, 38.1 grams of heptane present in 100 grams of solution

So, 65.0 grams of heptane present in grams of solution

Since, there is only 20.0 grams of solution available. That means, there is not enough solution.

Thus, the correct answer is "No solution".

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
