Covalent compounds share with each other, whilst Ionic compounds take from each other. 

Covalent compounds are composed of 2 or more NONMETALS.

So, it would be CO, since the rest of the compounds contain metals in them.

If the volume of a confined gas is doubled while the temperature remain constant, what change (if any) would be observed in the
dimulka [17.4K]

The gas will obey Boyles Law:

P1 V1 = P2 V2      where P1 and V1 are the original pressure and volume and P2 and V2 are the new  values.

If V2 = 2V1  (given) then:

P1 V1 = P2 *2 V1

P2 = P1 V1 / 2V1

P2 = P1 / 2

In other words the pressure is halved. (answer).

2Na(s) + Cl2(g) ------ 2NaCl(s)
Dovator [93]

Answer:

1. 7.256g of NaCl

2. 47.33g of Cl2

Explanation:

2 moles of Na reacts to produce 2 moles of NaCl

8 moles of Na will still produce 8 moles of NaCl

Mass of NaCl = molar mass of Nacl/moles of Nacl

=58.5/8

=7.256g of NaCl

From the equation, 2 moles of Na reacts with 1 mole of Cl2

3/2 moles of Cl2 will react with 3 moles of Na

Mass of Cl2 = 71/1.5

=47.33g of Cl2
