3. Corev was synthesizing a chemical in the laboratory. He used different purification techniques to try to obtain a pure compound. The melting point of the pure compound is 65 degrees. When he tested his compound in the lab the melting point he obtained was 62-68 degrees. Is the product he synthesized pure? 4A company was low on copper metal and decided to use some chemical additives just this once to some copper wiring they were installing in a house. How will this impact the conductivity of the wiring?

I can't solve it can you please help me or tell me the answers
3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below. Volcano # 1 Time Volume of gas Volume of gas produced (mL) vs. Time (s) for Volcano #1 (s) produced (mL) 60 50 10 20 30 25 38 40 46 30 • Volume of gas produced (ml) 40 50 20 50 52 e 10 60 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas produced (mL) vs. Time (s)…

For questions #14-16, you should do your work on a separate piece of paper and then upload it. You should use the GUESS Method of solving for each problem. Also, you have a choice. You can complete both #14 & #15 which are single step question or do the extension problem which is a 2 step problem instead of 14 & 15. You must complete #16.
