Consider the following reaction between sulfur trioxide and water:

Chemistry
1 answer:
Sidana [21]3 years ago

Answer:

A. H2O, B. 60.9 g, C. 86.3%

Explanation:

SO3 (g)  +  H2O (l)  →  H2SO4 (aq)

Chemist equation is ballanced: ok

1 mol of SO3 reacts with 1 mol of water, to produce 1 mol of H2SO4

First step: Find out the mol of each reactant.

Mass of SO3 = 80 g/m

Mol of SO3 → mass /molar weight = 61.5 g /80g/m = 0.768 mol

Mass of water = 18 g/m

Mol of H2O → mass /molar weight = 11.2 g /18g/m = 0.622 mol

Second step: Discover the limiting reactant.

As the relation is 1:1 (SO3 - H2O), 0.768 mol of SO3 needs 0.768 mol of water and 0.622 mol of water needs 0.622 mol of SO3.

I don't have enough water, so H2O is my limiting.

Third step: Find out the yield.

Now that we know the limiting reactant we can work, and relation between  products is still 1:1 so 0.622 mol of water, produce 0.622 mol of H2SO4

Molar weight of H2SO4 = 98 g/m

Molar weight . mol = mass  → 98 g/m . 0.622 mol = 60.9 g

This is the 100% yield (Theoretical one) but the chemist collects only 52.6 g of sulfuric so to find the real yield, we can use the rule of three.

60.9 g _____ 100 %

52.6 g ______ (52.6 .100) /60.9 0 = 86.3%

A student was asked to determine the densities of the four metals listed. The student was asked to determine the density of an u
Iteru [2.4K]

Answer:

D is correct

Explanation:

because

we know that

density of lead is 11.36 g/cm3

and

density of tin is 7.31 g/cm3

so..

density of alloy by mixing 50/50

=(11.36+7.31)/2 g/cm3

=18.67/2 g/cm3

=9.33 g/cm3

How many water molecules (H2O) can be produced from 6 molecules of hydrogen gas (white) reacting with 6 molecules of oxygen gas
Vladimir79 [104]
I think you can only have 3 water molecules because you need 2 hydrogen molecules in every water molecule and you have 6 hydrogen molecules so 6/2=3 and the reactant that is limited would be hydrogen since it limits the amount of water molecules you can have

A 50.0 g sample of scandium, sc, is heated by exposure to 1.50 x 10 3 j. The temperature of the sc is raised by 61.1 o
statuscvo [17]

Given mass of Scandium = 50.0 g

Increase in temperature of the metal when heated = 61.1^{0}C

Heat absorbed by Scandium = 1.50*10^{3}J

The equation showing the relationship between heat, mass, specific heat and temperature change:

Q = m C (deltaT)

Where Q is heat = 1.50*10^{3}J

m is mass = 50.0 g

ΔT = 61.1^{0}C

On plugging in the values and solving for C(specific heat) we get,

1.50*10^{3}J=50.0g(C)(61.1^{0}C)

C = 0.491\frac{J}{g^{0}C }

Specific heat of the metal = 0.491\frac{J}{g^{0}C }
