Produces heat, putting off air or bubbles and changes the smell or odor it changes the state that’s how you know it is a chemical reaction
Number of atoms in 1 mole = 6.023 * 10²³
Number of atoms in 0.46 mole = 0.46 * 6.023 * 10²³
It is = 2.77 * 10²³ atoms (Approx.)
In short, Your Answer would be Option B
Hope this helps!
Answer:
pH = 3.65
Explanation:
given data
pKa of HNO2 = 3.40
nitrous acid (HNO2) = 0.110 M
NaNO2 = 0.200 M
to find out
What is the pH
solution
we get here ph for acidic buffer that is express as
pH = pKa + log(salt÷acid) ........................1
put here value and we get
pH = 3.40 + log(0.200÷0.110)
pH = 3.65
Answer:
