1. in a molecule of two electron dot structures describe the bonds equally well. water (h2o) carbon dioxide (co2) nitrogen (n2) ozone (o3)

carbon dioxide

Explanation:

Hello! The carbon dioxide molecule has a double covalent bond, where two pairs of electrons are shared. Carbon shares two electrons with one oxygen molecule and two electrons with another oxygen molecule. Each oxygen shares a pair of electrons so that carbon can complete its eight electrons in the last orbit. So each oxygen completes its eight electrons too.

- 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

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
