Halogens are a family of atoms (the penultimate column of the periodic table). They're composed of Fluorine, Bromine, Chloride, Iodine and Astatine.
Answer:
The smallest ballon is the ballon X
Explanation:
It is possible to answer this question by using Graham's law:
Where v is the speed of effusion and MW is molar weight of each compound.
This equation is showing that speed is inversely related to the square root of its molar mass. As carbon dioxide has a bigger MW than carbon monoxide, the speed of effusion of carbon dioxide is lower doing its ballon biggest than carbon monoxide ballon, thus: <em>The smallest ballon is the ballon X</em>

Answer:
Explanation:
We collected the gas over water; to obtain the true pressure of the gas, we have to correct for the vapor pressure of water. We look up the vapor pressure of water at 24 ºC: 24 torr. The pressure of the evolved gas is, therefore, 738 −24 = 714 torr. 2. We want the molar mass of the
Answer:
Diamond is burnt
Diamond (Carbon)+ Oxygen → CO2
Water electrolysed
2H2O → 2H2 + O2
Explanation:
Dalton atomic theory states that in a chemical reaction, the atoms of the elements join together or combine in simple whole number ratios
Hence when, at very high temperatures, diamond which consists of carbon is burnt we have
Diamond (Carbon)+ Oxygen → CO2
Also when water is electrolysed it decomposes as follows
2H2O → 2H2 + O2
