Which one of the following substances is more likely to dissolve in CCl 4? CBr4 HBr HCl CH3CH2OH NaCl

CBr4

Explanation:As a general solubility rule: 'like dissolves like'

that is more polar compounds can easily dissolve in polar solvents while non-polar compound can easily dissolve in non polar solvents.

Carbon tetracholride, CCl4, is a non polar solvent and CBr4 is also non polar hence it dissolves easily in ccl4.

While the rest of the compounds mentioned above are polar in nature hence they wont dissolve easily in ccl4.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
