3) In the combustion reaction of methane gas: CH4 (8) + O2(g) CO2 (g) + 2 H2O (8) 4.0 X 10 exp 23 molecules of CH4 was used. Determine (a) the moles of CO2 produced (b) using your answer in (a), calculate the volume of CO2 produced at STP (c) the volume of oxygen used in the reaction at STP​

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

i do not get it   at all

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
