Answer:
105 grams PbI₂
Explanation:
Pb(NO₃)₂ + 2KI => 2KNO₃ + PbI₂(s)
moles Pb(NO₃)₂ = 0.265L(1.2M) = 0.318 mole
moles KI = 0.293(1.55M) = 0.454 mole => Limiting Reactant
moles PbI₂ from mole KI in excess Pb(NO₃)₂ = 1/2(0.454 mole) = 0.227 mol PbI₂
grams PbI₂ = 0.227 mol PbI₂ x 461 g/mole = 104.68 g ≈ 105 g PbI₂(s)
Chemical properties of elements are primarily determined by the electrons but not by the neutrons. Therefore, Isotopes can have different number of neutrons and electron,but not protons
I think carbon monoxide and sodium chloride are the organic compounds.
I hope this helps :-)
X, Y, and Z are elements.
An element is the smallest part of a substance that can exist on its own and can not be broken down into smaller unit.
From the question, W was broken down to give X, Y, Z. All three substances can not be broken down by chemical means.
The fact that X, Y and Z can not be broken down by chemical means implies that they are elements.
