Answer:
6,9,7,10,8,11..
Step-by-step explanation:
If you notice that in the given sequence 6, 9, 7, 10, 8 the first element is 6 and then 3 is added in 6 to make it 9. Then 2 is subtracted from 9 which makes it 7 and then again 3 is added in 7 which makes it 10. After that again 2 is subtracted from 10 to make it 8. Now by following this method now we will add 3 in 8 which will give us the next item which is 11.
Thus the sequence we get is:
6,9,7,10,8,11...

Answer:
ethanol
Step-by-step explanation:
The enthalpy of combustion is the amount of heat produced when one mole of ethanol undergoes complete combustion at 25 ° C and 1 atmosphere pressure, yielding products also at 25 ° C and 1 atm.
The enthalpy of combustion of the unknown compound is
ΔH = - 320 kJ / 0.25 mol = - 1280 kJ / mol
To choose a probable compound according to this combustion enthalpy, we must evaluate the deviation in relation to the values reported in the literature for the three probable compounds (methane, ethylene and ethanol). The deviation (e%) will be calculated according to the following equation,
e% = ( | ΔHx - ΔH | / ΔHx ) x 100%
where ΔHx is the enthalpy of combustion of the probable compound.
The following table shows the combustion enthalpies of the probable compounds and their deviation in relation to the enthalpy of ΔH = - 1280 kJ / mol
Compound Enthalpy of combustion (kJ/mol) Deviation
Methane - 890.7 43.8%
Ehylene -1411.2 9.3%
Ethanol -1368.6 6.5%
According to the previous table, we can say that the most probable compound is ethanol, since it has the smallest deviation in relation to the experimental enthalpy value of combustion.

Formula for area of parallelogram:
A= Base x Height
Here Area, A= 18 1/3 ft²
Height, H=3 1/3 ft
Convert the mixed number into improper fraction.
18 1/3 = 55/3
and 3 1/3= 10/3
Put values in formula to get the length of base.
55/3=B x 10/3
Multiply both sides by 3.
55=10B
Divide both sides by 10.
55/10=B
or
B=11/2 ft
or
B= 5 1/2 ft
Answer: Base of window is 11/2 ft or 5 1/2ft
Here’s the answer, hope it helps!
