An organic molecule has 10 carbons and 22 hydrogens. It must be made of... all double bonds single bonds with one triple bond single bonds with two double bonds single bonds with one double bond all single bonds

All single bonds.

Explanation:

To calculate the number of single, double or triple bonds (unsaturations), for molecules containing only carbon, hydrogen, monovalent halogens, nitroge , as the organic molecule C10H22 has, we use the following formula,  also known as the hydrogen deficiency index (HDI):

Where

C = number of carbon atoms

H = number of hydrogen atoms

X = number of halogen atoms

N = number of nitrogen atoms

2 gives an equivalent result.

Since the number of unsaturations is zero, it means that the molecule only has single bonds, it does not have double or triple bonds and it does not have rings.

i'm not sure

explanation:

i'll try whatever you got

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
