Darrell finds a bottle of what looks like clearwater with dirt settled at the bottom when he shakes the bottle if the water gets dirty which term best describes the matter in the bottle

Explanation:

A mixture in which solute particles are present in a non-uniform composition in the solute is known as a heterogeneous mixture.

For example, mud in water is a heterogeneous mixture.

On the other hand, a mixture in which there is uniform composition of solute particles in the solvent is known as a homogeneous solution.

For example, sugar dissolved in water is a homogeneous solution.

Therefore, we can conclude that the given solution is a heterogeneous mixture.

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
