F Ne

Explanation:

From the given table, we can simply complete the given table by identifying the meaning of each column header.

Number of protons in an atom is the number of positively charged particles in the nucleus of the atom. Protons are positively charged particles in an atom.
The number of neutrons are the number of neutrally charged particles occupying the nucleus of an atom.
Atomic number is another term for the number of protons in an atom.
Mass number is the sum of protons and neutron in an atom.
The symbol of an element is used represent a particular atom.

Mass number = number of protons + number of neutrons

Atomic number = number of protons = number of electrons in atoms.

Which answer is correct for the question below? Why would number <br> Two be incorrect?

Lapatulllka [165]

It would be 4 because the graph is showing the impact of heat on the enzyme not the pH. The pH in this instant is the constant and the graph does not indicate what a change in pH would do, only what a change in temperature would do.

A solution was prepared by mixing 0.5000 m hno2 with 0.380 m no2-. ka = 4.58 x 10-4. calculate the ph of the solution. show work

adell [148]

pH of buffer can be calculated as:

pH=pKa+log[salt]/[Acid]

As ka = 4.58 x 10-4

Concentration of [Salt] that is NO2(-1)=0.380M

Concentration of [Acid] that is HNO2=0.500M

So, pH= -log(4.58*10^-4)+log((0.380)/0.500))

=3.21

So pH of solution will be 3.21
