Which of the following is an advantage of using an incinerator to dispose of waste?

a. can produce energy

b. competes with recycling centers

c. more expensive than burying waste

The answer would be:

A. Can produce energy

Here's more about your question, if you'd like to know more:

Waste incinerators help with reducing waste, especially solid waste. Although it is not seen as the ideal way of disposing of waste, it can help by reducing the need for more land to keep it. Another advantage would be its ability to produce energy, heat energy and electricity to be exact.

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

the answer to this question is 3.
