An oak tree gets nourishment from the Sun and produces acorns. Squirrels eat the acorns. What has happened to the matter consumed by the squirrel? A.
The matter is converted to energy and carbon molecules.
B.
The matter is completely consumed by the squirrel.
C.
The matter is completely eliminated by the squirrel as waste.
D.
The matter is converted to energy only.

- 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

b

explanation:

mitosis

a:

by the combination of an unlimited number of elements

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
