Answer:
b. independent/manipulated variable
Explanation:
Independent/manipulated variable - refers to the variable that is changed by the scientist or an experimenter. Only one variable that is independent is required to ensure a fair test in an excellent experiment. As the independent variable is being changed by an experimenter or scientist, data is being recorded simultaneously as they are collected.
3. The answer is B. 11. This is because there are the same amount of electrons and protons in an atom, and since there are 11 protons, there are 11 electrons.
5. The formula H2O means that there are 2 hydrogen atoms (because the 2 is after the H), and 1 oxygen atom, so the answer is C.
Hope this helps!
Answer:
Hello! so this is what I was able to find related to your question.
Explanation:
The oxidation number of this molecule, called a bromate molecule, is -1. It should be correctly written BrO3-. It has this net charge of negative 1 because the bromine has an oxidation number of +5, while oxygen has it's normal oxidation of -2.
Well, one mole would be considered as 6.02 x 1023 (atoms). Which in the copper form, this would be considered to be as 63.66 grams of copper. Know, by knowing this information, we're now able to figured out the question.
53.3 ÷ (atoms) 6.02 x 1023 ...
Which as a result, we then have 2665 over.
