Which statement is a good description of plastic?(1 point) It is a synthetic material that comes from natural resources. It is a synthetic material that does not come from natural resources. It is a natural material that is made from synthetic resources. It is a natural material made from natural resources.

Plastics are synthetic material that is made by natural material.

(I) is correct option.

Explanation:

Given that,

The statements are,

(I). It is a synthetic material that comes from natural resources.

(II). It is a synthetic material that does not come from natural resources.

(III). It is a natural material that is made from synthetic resources.

(IV). It is a natural material made from natural resources.

We know that,

Plastic :

Plastics are organic polymers of high molecular mass and often contain other material.

They are usually synthetic which is get from petrochemicals.

Through the polymerisation process, we get plastics from natural materials like, coal, natural gas, salt and crude oil.

So, We can say that, plastics are synthetic material that is made by natural material.

Hence, Plastics are synthetic material that is made by natural material.

(I) is correct option.

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
