Two angles with measures (6x + 60) (90) are supplementary. What is the value of x?

Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5

Exiting or five because in gem Dos you have to do parentheses first from left to right size 6X +60 is already simplified times 90 now you move your parentheses so you would multiply 16 times 9016×90 whatever that is you would add that to six facts which is not

Arrange the molecules in order from strongest intermolecular force to weakest.
motikmotik

Answer:- C_4H_1_0>C_3H_8>C_2H_6>CH_4

Explanations:- Alkanes are non polar molecules as these only have carbons and hydrogens. Electron negativity difference of C and H is very low and it makes them non polar. These have weaker London dispersion forces.

The forces of attraction becomes stronger in alkanes as the number of carbon increases because the surface area as well as molecular weight of the alkanes increases with an increase in number of carbons.

Butane has four carbons, propane has three carbons, ethane has two and methane has only one carbon, So, the strongest to weakest order of inter molecular forces is butane > propane > ethane > methane .

lys-0071 [83]

Answer:

so 0.15 moles X 22.4 dm3/mole=3.36 dm3. Next we find the moles of hexane combusted, and then the moles of CO2. Finally, we find the volume of CO2 using the fact that at STP, 1 mole of gas = 22.4 dm3.
