There are four fundamental forces existing in the universe so called universal forces. They are the strong nuclear force, the weak nuclear force, the electromagnetic force and the gravitational force. The strong nuclear force is the strongest force acting while gravityis weakest.
The chemical equation is:
<span>HCO3^ -> H^+ + CO3^2- </span>
We know that the formula
for Ka is:
Ka = [H^+][CO3^2-]/[HCO3^-]
log Ka = log[H^+] + log[CO3^2-]/[HCO3^-]
pKa = pH - log[CO3^2-]/[HCO3^-]
log[CO3^2-]/[HCO3^-] = pH - pKa = 10.75 - 10.329 = 0.421
<span>[CO3^2-]/[HCO3^-] = Antilog (0.421) = 2.636 </span>
Answer:
<span>2.636</span>
Answer: d Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.
