A scientist studies the amount of food gerbils eat based on how much
exercise they get. He has 100 gerbils. The scientist has each gerbil perform a
different amount of exercise and records how much food the gerbil eats.
What is the responding variable in this experiment?
O
A. The total number of gerbils
O
B. The amount of exercise performed by the gerbil
O
C. The amount of food eaten by each gerbil
O
D. The amount of sleep each gerbil gets

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

so what is the problem with your lab report and whats the subject of the lab report? i will you
