Answer:
Acidic
Explanation:
Please kindly check attachment for the detailed step by step solution of the given problem.
Answer:yes because due to ionization atom makes chemical bonds with other atoms, which makes change in the properties of atoms
Explanation:
Answer:
Mole fraction for solute = 0.1, or 10%
Molality = 6.24 mol/kg
Explanation:
22.3% by mass → In 100 g of solution, we have 22.3 g of HCOOH
Mass of solution = 100 g
Mass of solute = 22.3 g
Mass of solvent = 100 g - 22.3g = 77.7 g
Let's convert the mass to moles
22.3 g . 1mol/ 46 g = 0.485 moles
77.7 g. 1mol / 18 g = 4.32 moles
Total moles = 4.32 moles + 0.485 moles = 4.805 moles
Xm for solute = 0.485 / 4.805 = 0.100 → 10%
Molality → mol/ kg → we convert the mass of solvent to kg
77.7 g. 1 kg / 1000g = 0.0777 kg
0.485 mol / 0.0777 kg = 6.24 m
I don’t know what the answer is just need points sorry
Answer:
The volume will be 6, 67 L
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T:
P1xV1/T1 = P2 x V2/T2
V2= ((P1xV1/T1)xT2)/P2
V2=((1,5 atm x5 L/300K)x400K)/1,5 atm
V2=6, 67 L
