Answer: 43.

Explanation:

Mass number is the sum of protons and neutrons of an atom.

The number of prortons is the atomic number, so you can write:

Mass number = atomic number + number of neutrons. From which you get;

number of neutrons = mass number - atomic number = 80 - 37 = 43

All the atoms of a given element have the same number of protons. That is why the number of protons idenfies the elements and is called atomic number.

The number of neutrons of a given element may be different for different atoms of the same element.

The atoms of an element that have different number of neutrons are called isotopes. So, different isotopes of the same element have same atomic number but different mass number.

The atomic number will indicate the number of protons in an element and the mass number will indicate the sum of protons and neutrons in an element so from the given, to get the neutron you will just simply subtract. 80-37= 43 neutrons.

Is 4atm to big of a difference to get when I use the ideal gas law vs the van der waals equation?
garik1379 [7]

This absolute amount of pressure does not play a significant difference.

At high temperatures and low pressures, its results deviate too little.

But at low temperatures and high pressures, it will change significantly and this difference will change from gas to gas.

In the image you can see the difference between some results from both equations.

In this redox reaction, identify the element that was reduced.
malfutka [58]
I think the correct answer from the choices listed above is the third option. <span>In the redox reaction given, the element that was reduced was Fe or iron. It's charge reduced from +3 to zero, a neutral charge. Hope this answers the question. Have a nice day.</span>

Which compound has both ionic and covalent bonding?.
Nikitich [7]

Answer: Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded
