Answer:
We will need two potassium ions to balance the charge on the sulfate ion, so the proper chemical formula is K 2SO 4.
Explanation:

Atomic number of Fluorine-19 is 9. So, it must have 9 protons. As the mass number is 19, the number of neutrons will be 10.
In Tungsten-184, the number of protons is 74 and the number of electrons should also be 74.
In cobalt-59, the mass number should be 27 protons +22 neutrons = 49.
Answer:
The appropriate option will be Option A (unequal sharing of electrons in a covalent bond).
Explanation:
- A polar bond seems to be a covalent bond amongst two or even more atoms where there is an uneven distribution of the electrons surrounding the connection.
- This induces a small electrical magnetic dipole in the molecules whereby the end becomes generally favorable and another is mildly controversial.
The other choices aren't relevant to the situation presented. The answer above would be appropriate.
Answer is: d. increases.
<span>The velocity of sound in seawater changes with water pressure, depth, temperature and salinity.
</span>Velocity can be calculeted using Del Grosso's equation, the UNESCO equation (<span>International Standard algorithm)</span> or <span>Mackenzie equation.
