Answer:
Explanation:
pH = pKa + log [ CH₃COO⁻ ] / [CH₃COOH ]
5.36 = 4.86 + log [ CH₃COO⁻ ] / [CH₃COOH ]
log [ CH₃COO⁻ ] / [CH₃COOH ] = .5
[ CH₃COO⁻ ] / [CH₃COOH ] = 3.16
moles of CH₃COOH = .680 x .9 = .612 M
Let x mole of KOH is required
x /( .612 - x ) = 3.16
x = 1.933 - 3.16 x
x = .46488
.46488 moles of KOH will be required
volume required be V
v x 2.62 = .46488
v = .1774 L
= 177.4 mL
177.4 mL of 2.62 M KOH will be required .
Place your hand in front of your face. Now push it away from your body. Which looked bigger?
Thermal energy equation is;
Q = mcΔθ
Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference
the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.
A gaseous solute will <span> be able to be dissolve in a liter of liquid water by increasing the pressure of the gas. an example of this situation is the increase in solubility of carbon dioxide in sea water which turns it into an acidic environment for marines as pressure increases.</span>
