Explanation: Here are the different coloured that are used to join and make one piece this method that Brianna is following is called synthesis.
Answer : Option C) 0.3 mol of Gold.
Explanation : Amongst the options given in the question, 0.3 mol of Au is the greatest in mass in grams.
As 0.3 mol X atomic weight of Au (196.966) = 59.088 grams;
Silver has 0.5 mol X atomic weight of Ag (107.86) = 53.93 grams;
The other options are not relevant as they deal in the atomic range which has mass value very less as compared to the moles of elements.
Therefore, it is clear that Au has the greatest mass amongst the given choices.

Explanation:
The solvent is a base or medium , in which reaction takes place ,
Mostly organic solvents have hydrogen and carbon , and is purposely used to dissolve the organic sample .
The example of organic solvents , used in laboratory are as follows -
1. Toluene
2. Hexane
3. Pentane
4. Benzene
5. Methanol
The answer would look something like this. (sorry for the ugliest diagram ever.)
