Answer is: 1.29 grams <span>of solid formed.
</span>Chemical reaction: 2AgNO₃(aq) + K₂CrO₄(aq) → Ag₂CrO₄(s) + 2KNO₃(aq).
n(AgNO₃) = c(AgNO₃) · V(AgNO₃).
n(AgNO₃) = 0.220 M · 0.0351 L.
n(AgNO₃) = 0.0078 mol; limiting reactant.
n(K₂CrO₄) = 0.420 M · 0.052 L.
n(K₂CrO₄) = 0.022 mol.
From chemical reaction: n(AgNO₃) : n(Ag₂CrO₄) = 2 : 1.
n(Ag₂CrO₄) = 0.0078 mol ÷ 2.
n(Ag₂CrO₄) = 0.0039 mol.
m(Ag₂CrO₄) = 0.0039 mol · 331.73 g/mol.
m(Ag₂CrO₄) = 1.29 g.
I would think that it’s C, but try to get a second opinion as well!!
a.uses of functional groups involving oxygen
Answer:
Reason: Gravitational pull of the Moon
Explanation:
Weight of Garfield is 24 lbs on the Earth. He took a flight from the Earth to the Moon where the gravity is 1/6 of the gravity on the Earth.
But when reaches the Moon he found he weighed only 6 lbs. It is due to the gravitational pull of the Moon.
Mass of an object reamins the same at every location while its weight changes due to the change in acceleration due to gravity. It is equal (on Moon) to 1/6 the of acceleration due to gravity on the earth.
Answer:
B
Explanation:
Molarity measures the strength of a solution. Remember, a solution is made up of two parts: the solvent (which does the dissolving) and the solute (the substance that is dissolved). The more solute there is, the higher the concentrate and therefore the higher the molarity of the solution. Thus B is the answer
