Answer:
nonrenewable
Explanation:
It's just an educated guess but you know plastic bottles and stuff like that contribute to pollution
Aluminum mixed iron .Al + fe = AlFe3
Answer: C) 0.020 m
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
Mole fraction of is = i.e. moles of is present in 1 mole of solution.
Moles of solute =
moles of solvent (water) = 1 - = 0.99
weight of solvent =
Molality =
Thus approximate molality of in this solution is 0.020 m
