What is charge on the cation SnCl4
2 answers:
<u>Answer:</u> The charge on the cation is +4
<u>Explanation:</u>
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation.
- When an atom gains electrons, it results in the formation of negative ion known as anion.
We are given a chemical compound having chemical formula of
It is formed by the combination of tin ions and chloride ions.
Tin is the 50th element of the periodic table having electronic configuration of
This element will loose 4 electrons to form ion
Chlorine is the 17th element of the periodic table having electronic configuration of
This element will gain 1 electron to form ion
Thus, the charge on the cation is +4

Answer:
There are 5.69*10²⁴ molecules in 9.45 moles.
Explanation:
The mole is defined as the amount of matter that particles have, that is, atoms and elementary entities.
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.
Then the following rule of three can be applied: if 1 mole contains 6.023 * 10²³ molecules, 9.45 moles, how many molecules will it have?
Solving:
amount of molecules= 5.69*10²⁴⁴ molecules
<u><em>There are 5.69*10²⁴ molecules in 9.45 moles.</em></u>
