What class of minerals form when the element si is bonded with element o, as in the mineral quartz?

In the mineral quartz or glass there are three types of si-O combined compound. Those are silicon dioxide or silica (), sodium silicate () and calcium silicate (). The preparation of the compounds can be shown as-

1. Si (s) + (g)→ Si (s)

2. Si (s) + NaO (s) → (s)

3. Si (s) + CaO (s) → (s)

As we can see that all the compounds are solid in nature and their composition makes the quartz.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

idk what is it? is this a question that you know the answer or u dont
