Answer:
D. MgO
Explanation:
We need to look at the charge of element. (Look at a periodic table for this)
Mg, which is Magnesium, has a charge of 2+ because it's in the second column, or group, from the left.
O, which is Oxygen, has a charge of 2- because it's in the second column, or group, from the right.
Since Mg is 2+, it's the cation and since O is 2-, it's the anion. We can put these two elements together into an ionic compound.
Mg^(2+) and O^(2-) becomes Mg2O2, where we can cancel the 2s: MgO.
Thus, the answer is D.
Hope this helps!
The volume of the given solution is 2.5 L.
<u>Explanation:</u>
Volume of the solution = 2500 mL
We have to convert it into litres as,
1000 mL = 1 litre
To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.
Here given volume is 2500 mL.
Volume in L =
= 2.5 L
So the volume of the solution is 2.5 L.

Answer: Charge on the nucleus of an Uut element is +113
Explanation: A nucleus of an element consists of 2 subatomic particles: Protons and neutrons
Charge on 1 neutron = 0
Charge on 1 proton = +1
Number of protons = Atomic Number of the element
Atomic Number of the element Uut = 113
Number of protons = 113
Number of neutrons = Atomic mass - Number of protons
Atomic mass of Uut = 286 amu
Number of neutrons = 286 - 113 = 173
Charge on the nucleus is calculated by:


Charge on the Uut nucleus = +113
