The percent yield for this reaction is 91%.
<u>Explanation</u>:
Ba(NO3)2 + Na2SO4 — > BaSO4 + 2NaNO3
-
Assume that 0.45 mol of Ba(NO3)2 reacts with excess Na2SO4 to create 0.41 mol of BaSO4.
-
Convert to grams of BaSO4 utilizing its molar mass (233.38 g/mol), which will be giving the actual yield.
-
Actual Yield = 0.41 mol BaSO4 x (233.38 g BaSO4/1 mol BaSO4)
= 96 g BaSO4
-
Beginning with 0.45 mol of Ba(NO3)2, compute the theoretical yield of BaSO4. Mole proportion of Ba(NO3)2 to BaSO4 is 1:1.
-
0.45 mol Ba(NO3)2 x (1 mol BaSO4/1 mol Ba(NO3)2) x (233.38 g BaSO4/1 mol BaSO4) = 105 g BaSO4
% Yield = (Actual Yield/Theoretical Yield) x 100%
= (96/105) x 100%
= 91%.
It is very rare that a planet resembles Mars, in fact it is the rarest type of planets among the known planets so far. Even the planets that do share some characteristics with Mars, they also have characteristics that make them different, especially their size and distance from their star.
Answer:
the water repels the pencil
Explanation:
Since the an electrically charged pencil is placed close to the water running from a faucet :D
Answer:
<span>When identical particles pack in a simple cubic lattice, there is ONE particle per unit cell.
Explanation:
As we know that simple cube has eight corners and each particle at every corner is shared by eight cubic crystals. So it means that only </span><span>eighth </span>part of a particle is present at one corner of each cube. Therefore, each corner contain 1/8 particle, then all corners will contain 1/8 × 8 = 1 particle.
