The answer is c hopefully I helped you
If 1000 ml (1 L) of CH₃COOH contain 1.25 mol
let 250 ml of CH₃COOH contain x
⇒ x =
= 0.3125 mol
∴ moles of CH₃COOH in 250ml is 0.3125 mol
Now, Mass = mole × molar mass
= 0.3125 mol × [(12 × 2)+(16 × 2)+(1 × 4)] g/mol
= 18.75 g
∴ Mass of CH₃COOH present in a 250 mL cup of 1.25 mol/L solution of vinegar is <span>18.75 g</span>
Answer:If the pressure of a gaseous reaction mixture is changed the equilibrium will shift to minimise that change. If the pressure is increased the equilibrium will shift to favour a decrease in pressure.

Answer:

Explanation:
Given that
Mass ,m= 8.8 x 10¹³
Speed ,v= 33 km/s
We know that 1 km= 1000 m
v= 33 x 10³ m/s
As we know that kinetic energy given as

Now by putting the values in the above equation


Therefore we can say that the kinetic energy will be
