6840 is the answer hope this help
Answer:
Correct option: A
Explanation:
Equilibrium means the state of reaction which there is no net changes occur it means the rate of forward reaction and rate of backward reaction become same and also it does not mean that the concentration of both side i.e. reactant and product become equal. after gaining equlibrium position the concentration of reactant and product remain same and also chemical reaction does not stop and it continues.
Answer : The molar mass of solute is, 89.9 g/mol
Explanation : Given,
Mass of solute = 5.8 g
Mass of solvent (water) = 100 g
Formula used :
where,
= change in freezing point
= temperature of pure solvent (water) = 
= temperature of solution = 
= freezing point constant of water = 
m = molality
Now put all the given values in this formula, we get
Therefore, the molar mass of solute is, 89.9 g/mol
Answer:
Yes
Explanation:
Because mixture is made up of two or more types of atoms .
cations are formed when a metal loses electrons, and a nonmetal gains those electrons.
