Answer:
The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.
Explanation:
Answer: it is a good conductor of electriciy tht is what wires are made of and it is a good conductor of heat so it will be able to handle the heat from the electricity
Explanation:
Answer : The molecular weight of a gas is, 128.9 g/mole
Explanation : Given,
Density of a gas = 5.75 g/L
First we have to calculate the moles of gas.
At STP,
As, 22.4 liter volume of gas present in 1 mole of gas
So, 1 liter volume of gas present in
mole of gas
Now we have to calculate the molecular weight of a gas.
Formula used :
![\text{Moles of gas}=\frac{\text{Mass of a gas}}{\text{Molecular weight of a gas}}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20gas%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20a%20gas%7D%7D%7B%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%7D)
Now put all the given values in this formula, we get the molecular weight of a gas.
![0.0446mole=\frac{5.75g}{\text{Molecular weight of a gas}}](https://tex.z-dn.net/?f=0.0446mole%3D%5Cfrac%7B5.75g%7D%7B%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%7D)
![\text{Molecular weight of a gas}=128.9g/mole](https://tex.z-dn.net/?f=%5Ctext%7BMolecular%20weight%20of%20a%20gas%7D%3D128.9g%2Fmole)
Therefore, the molecular weight of a gas is, 128.9 g/mole

Answer:
16,,24Mg 17,,a24.1 18a mass number of the most abundant isotope
Explanation:
atomic number of Mg is 12 ,therefore its mass number should be the value that is very close to 24.
24.1 is the value of thee most abundant isotope.
