Ch4 and ch3ch2ch3 have the lowest boiling points because they experience only \rm ch_4 and \rm ch_3ch_2ch_3 have the lowest boiling points because they experience only the effects of which increase with increasing the effects of which increase with increasing \rm ch_4 and \rm ch_3ch_2ch_3 have the lowest boiling points because they experience only the effects of which increase with increasing

Dispersion forces

Relative molecular mass

Explanation:

Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
