Answer:
Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.
Answer: C.) It burns and causes lung cancer
Answer:
The answer is D
Explanation:
Although natural processes continually form fossil fuels, such fuels are generally classified as non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. ... The use of fossil fuels raises serious environmental concerns.

Answer: The molecular formula will be
Explanation:
If percentage are given and we are given total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 31.17 g
Mass of H = 6.54 g
Mass of O = 62.29 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of H=
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C=
For H =
For O =
The ratio of C: H: O= 1: 2.5: 1.5
Converting them into whole number ratios by multiplying by 2.
Hence the empirical formula is
The empirical weight of = 2(12)+5(1)+3(16)= 77 amu
The molecular weight = 231.2 amu
Now we have to calculate the molecular formula.
The molecular formula will be=
The molecular formula will be
