Answer:
A compound has atoms of different elements chemically joined together They can't be separated without a chemical reaction.
Answer: glass is not considered as solute.
Extra's:
A solute is a substance that gets dissolved in a solvent. ... The solutes in air are oxygen, argon, and carbon dioxide gas, as well as water vapour.
Sugar is a solute in the solvent water. Sugar is one of the most soluble solutes in water.
Also solute is a powder that can be dissolved in solvent like water. here baking soda is a solute.
THE MASS OF 2.5 IS THE AMOUNT OF THE LINER EQUITATION SO DIVIDE 2.5 INTO 23 GRAMS AND MULTIPLY YOUR PROFIT BRO BTW IM NOT A COP SO STAY COOL MY FRIEND
Answer:- False.
Explanations:- One mole of any gas at STP occupies 1 volume of 22.4 L.
STP means standard temperature and pressure. Standard temperature is 273 K and standard pressure is 1 atm.
Here, in the statement the given temperature is 298 K which is not the standard temperature and so the volume of 1 mole of the gas will not be 22.4 L.
The volume could be calculated using ideal gas equation:
PV = nRT
![V=\frac{nRT}{P}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7BnRT%7D%7BP%7D)
R is the universal gas constant and it's value is
.
let's plug in the values and calculate the volume for 1 mole of the gas:
![V=\frac{1mol*\frac{0.0821atm.L}{mol.K}298K}{1atm}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1mol%2A%5Cfrac%7B0.0821atm.L%7D%7Bmol.K%7D298K%7D%7B1atm%7D)
V = 24.5 L
The volume for 1 mol of the gas at 298 K and 1 atm is 24.5 L and hence the statement is false.
