Which of the following elements has the highest first ionization energy: Na, Mg, S or Cl?

Chemistry
1 answer:
storchak [24]3 years ago
3 0

Answer:

Cl has the highest ionization energy because all these elements lie in the same period and ionization energy increases from left to right across a period as Cl is the at the last in this period so it has the highest ionization energy

Explanation:

I hope it will help you:)

How does the number of subatomic particles change as the carbon isotope<br> decays?
Rzqust [24]

Answer:

Explanation:

C decays by a process called beta decay. During this process, an atom of 14C decays into an atom of 14N, during which one of the neutrons in the carbon atom becomes a proton. This increases the number of protons in the atom by one, creating a nitrogen atom rather than a carbon atom.

A sample of an uranium compound is found to be losing mass gradually. Explain what is happening to the sample.​
yan [13]

Answer:

The uranium in the sample of the compound is radioactive

Explanation:

Some atoms can split on their own. Some split when bombarded by energetic particles. Such atoms are said to be radioactive.

Radioactivity is borne out of the drive of an atom to reach stabillity. Every atom have a specific neutron/proton ratio which ensures stability of the nucleus. A nucleus with a stability ratio different from that which makes it stable will become unstable and split into one or more other nuclei with emissons of energetic particles.

Note: neutrons and protons dictates the mass of an atom. They are located in the nucleus which is the site for nuclear radioactive reactions.

you are given an unknown gaseous binary compound. when 10.0g of the compound isburned in excess oxygen, 16.3g of water is produc
Flauer [41]
Since the compound has 1.38 time that of oxygen gas at the same conditions of temperature and pressure, we have the relationship:
MW/MWoxygen = 1.38
MW = 44.16

Since there is water formed during the reaction, the formula of the compound must be:
XaHb
where a and b are the coefficients of each element.

If the compound reactions with oxygen forming water and an oxide of the element X, the combustion reaction must be:
XaHb + ((2a + (b/2))/2) O2 = a (XO2) + (b/2)(H2O)
Using dimensional analysis:
10 (1/44.16) (b/2 / 1) (18) = 16.3
Solving for b:
b = 8

The compound now is XaH8. Most probably, the compound is C3H8 since it has a molecular formula of 44 and it reacts with O2 to form water and CO2.
