Living things have many characteristics for example we are made up of cells, we use energy and we reproduce
The percent yield of a chemical reaction is calculated by dividing the actual yield (determined through experimentation) by the theoretical yield (calculations). The percent yield is a great way of determining the efficiency of a reaction. For this problem, the percent yield is 83.93% as given by the solution:
% yield = (47/56)*100 = 83.93%
Well since i need points I am going to say read the text
The Correct choices are :
- 1. The elements have filled valence levels.
- 2. potassium (K) with a 1+ charge
