We are going to apply the equation of state for ideal gasses: P*V = n*R*T where P is pressure, V is volum, n is mols of gas, T is temperature and R is a constant value of 0.082 (atm*l)/(mol*K)
We know the temperature is 45 ÂşC so in Kelvins will be = 45 + 273.16 = 318.16 K
Then in the equation:
V = n*R*T/P = 1.5 * 0.082 * 318.16 / 2.5 = 15.65 l
So volum of gas is: 15.65 liters
Explanation:
NaCl is a strong salt of strong base and strong acid whereas HCl is a strong acid.
In the solution both dissociates in the solution into their respective ions as shown below:
NaCl ⇒ Na⁺ + Cl⁻
HCl ⇒ H⁺ + Cl⁻
Hence, the ions Na⁺, Cl⁻ and H⁺ are formed and there is no scope of reaction between them for a gas to evolve. They remain in the hydrated state in water.
The answer is D. Carbon dioxide + Water + Light source = Sugar and oxygen
Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution
Question 2: Answer is (B), Soil Conservation Act (1936)
Hope that helps!!!
