A: carbon
b: nitrogen
type of bond: covalent bond
formula: a3b4
To get the ratio of the concentration of sodium acetate to the concentration of acetic acid we are going to use H-H equation:
when:
PH = Pka + ㏒[salt/acid]
when the Ka of acetic acid = 1.75 x 10^-5
so, we can get Pka from this formula:
Pka = -㏒Ka
= -㏒1.75 x 10^-5
= 4.76
and when we have PH = 5.75, so by substitution:
∴ 5.75 = 4.76 + ㏒[acetate/ acetic acid]
∴ [acetate/acetic acid] = 9.77
∴ the ratio of a concentration of acetate to acetic acid 9.77
I think it's oxide and halide
(a) it was formed when electrons were shared
NaCl is an ionic bond which means an electron(s) was transferred (from one atom to another to make them stable) not a covalent bond which means an electron(s) was shared
Answer:
This is what they usually do.
Explanation:
Scientists are often people who want to see change occur. ... Today, the role of a scientist is the same. We have the obligation to explore and discover. Scientists use their resources to bring about change, whether it is change in medicine, improvements in the environment, or creating more efficient fuels
