Answer:
100mL of 0.10M HNO2 and 0.10M NaNO2
Explanation:
because solution has the greatest buffering capacity when the concentration of the weak acid is = at the concentration of its conjugate base.
Answer:
0.25 g of U-235 isotope will left .
Formula used :
where,
N = amount of U-235 left after n-half lives = ?
= Initial amount of the U-235 = 1.00 g
n = number of half lives passed = 2
0.25 g of U-235 isotope will left .
The water molecule is a polarized molecule containing 2 Hydrogen and 1 Oxygen. Oxygen has a bit more attraction for electrons than Hydrogen. Oxygen is more electronegative, so it’s going to have a stronger pull on electrons.
Answer: 0.8 M
Explanation:
molarity = (moles of solute)/(liters of solution) = 1.25/1.5 = 0.8 M
