For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well
Hop this helps!!
Answer:
a0=2
a1=3
a2=2
a3=4
Explanation:
The balanced equation for the complete combustion of methane is:
2CH₃OH₍l₎ + 3O₂₍g₎ → 2CO₂ + 4H₂O₍l₎
This way, there is an equal number of atoms of each kind on both reactants side and the products side.
Therefore the coefficients represented by the unknowns are:
a0=2
a1=3
a2=2
a3=4
The above is the equation for the complete combustion of methanol.
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.
