Answer:
Molarity of HCl solution = 0.25 M
Explanation:
Given data:
Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)
Molarity of NaOH solution=M₁ = 0.185 M
Volume of HCl solution = V₂ = 0.0200 L
Molarity of HCl solution = M₂= ?
Solution:
M₁V₁ = M₂V₂
0.185 M ×0.025 L = M₂ × 0.0200 L
M₂ = 0.185 M ×0.025 L / 0.0200 L
M₂ = 0.005M.L /0.0200 L
M₂ = 0.25 M
Answer:
Partial pressure of CO2 = 16 atm
Explanation:
Total number of moles of gases = 4+1 = 5 moles
Mole fraction of CO2 = 4/5
Partial pressure of CO2 = mole fraction of CO2 × total pressure
Partial pressure of CO2 = (4/5) × 20
Partial pressure of CO2 = 16 atm
Answer:
A delta is formed when the river deposits its material faster than the sea can remove it. ... Cuspate - the land around the mouth of the river juts out arrow-like into the sea. The Ebro Delta. Bird's foot - the river splits on the way to the sea, each part of the river juts out into the sea, rather like a bird's foot.

Answer:
No
Explanation:
given that, enthalpy is a state function, that means it depends only on the initial and final states, there is no difference between the enthalpy of a phase transition versus the enthalpy of a heating or cooling process, when the cooling or heating process finish in a change of phase.
It does not matter which way we take to cool or heat the substances the Enthalpy of this process will be the same.
