Answer:
Evaporation
Explanation:
Boiling the water will make it evaporate, leaving the solid at the bottom of the solution
Answer: The correct answer is 'increases to 100 times the original concentration'.
Explanation:
let the initial pH be x
The original concentration of initially present be y
...(1)
Final concentration of when pH reduced by 2 be z
...(2)
Putting the value of 'x' from (1) into (2) we get :
When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration
Fluorine gas effuses 1.37 times faster than chlorine gas
calculation
Rate of F2/rate of Cl2 =√ molar mass Cl2 / molar mass F2
rate of F2/Rate of Cl2 = √1.868
rate of F2/rate of Cl2 =√ 71/38 = 1.37 times faster than chlorine
Answer:
Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two
Explanation:
Answer:
Data:
mass of solute: 35g of NaCl
m.mass of solute: 58g/mol
volume of solution: 501mL
Molarity=?
Explanation:
501ml = 0.5dm3
M= g of solute/m.mass of solute*vol of solution
M= 35/58*0.5
M=1.20
