Q#13 how many moles of mgcl2 are there in 350. g of compound?

3.67 moles

Step-by-step explanation:

We need to find out the number of moles present in 350 grams of a compound.

Molar mass of = 24.305

Molar mass of = 35.453

So, one mole of = 24.305 + (35.453 * 2) = 95.211g

1 Mole in 1 molecule of =

Therefore, number of moles in 350 grams of compound = 0.0105 * 350

= 3.67 moles

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
