Answer:
I think its D. and A hopefully that's right
Look those up it will be easier
Answer:
Ionic bonding involves the transfer of electrons from a metal atom to a non-metal atom until the outer shells of their resultant atoms are similar to that of a noble gas. The metals lose electrons and form cations while the non-metals accept the electrons and form anions.
Answer:
The pH at the midpoint in the titration of an acid with a base is
A) equal to the pK of the corresponding base.
B) equal to the pK of the corresponding acid.
C) equal to 14 minus the pK of the corresponding acid.
D) equal to 14 plus the pK of the corresponding base.
E) none of the above
Explanation:
When a weak acid is titrated with a strong base, then a buffer solution is formed.
pH of a buffer solution can be calculated by using the formula:
Exactly at the mid point,
[conjugate base of the salt]=[acid]
So, log [salt]/[acid] =0
Hence, pH of the solution will be equal to pKa of the weak acid.
Answer is option B.
Gases
there are 4 states of matter, solid liquid gas and plasma, but plasma doesn’t make sense for this question so the answer would be gas
