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)
Answer: plate
Explanation: Plates grinding past each other in opposite directions create faults called transform faults. Powerful earthquakes often strike along these boundaries. The San Andreas Fault is a transform plate boundary that separates the North American Plate from the Pacific Plate.
Answer: correct answer is D
It can be traced example in copper rod or iron or any other pure metal
Answer: a)
is the limiting reagent
b) 3.59 g
c) 11.6g
Explanation:
To calculate the moles :


According to stoichiometry :
a) 9 moles of
require= 4 moles of
Thus 0.15 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
b) As 9 moles of
give = 8 moles of 
Thus 0.15 moles of
give =
of 
Mass of 
c) As 9 moles of
give = 3 moles of 
Thus 0.15 moles of
give =
of 
Mass of
