What is the maximum mass of s8 that can be produced by combining 89.0 g of each reactant?
lidiya [134]

Answer : We can produce 125.7 g of S_{8}.


Explanation : The reaction will be

8SO_{2} + 16H_{2}S -----> 3S_{8} + 16H_{2}O


The molecular mass of SO_{2} is 64.1 g/mol

and molecular mass of H_{2}S is 34.1 g/mol


For every mole of SO_{2} we would need twice of H_{2}S moles, so for every 3 moles of S_{8} we need 16 moles of H_{2}S


Now, we can calculate number of moles S_{8}

2.61 X (3/16) = 0.49 moles


Here, the molecular mass of S_{8} is 256.8 g


multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of S_{8}.


Hence, 125.7 g of S_{8} will be produced.

Classify each of the four compounds as a conjugated, isolated, or cumulated diene. Compound A: Two alkenes are joined by a sigma
Lina20 [59]

Explanation:

Conjugated diene is the one that contains alternate double bonds in its structure. That means both the double bonds are separated by a single bond.

Cumulated diene is the one that contains two double bonds on a single atom. This means it has two double bonds continuously.

Isolated double-bonded compound has a single bond isolated by two to three single bonds.

Compound A: Two alkenes are joined by a sigma bond.

For example:

-CH_2=CH-CH=CH2-

It is a conjugated diene.

Compound B: Two alkenes are joined by a C H 2 group.

It is a cumulative diene.

Compound C: Two alkenes are joined by C H 2 C H 2.

Then it is an isolated alkene.

Compound D:  A cyclohexene has a double bond between carbons 1 and 2. Carbon 3 is an sp 2 carbon that is bonded to another s p 2 carbon with an alkyl substituent.

Hence, compound D is a conjugated diene.

if the volume of a gas contracted from 648 mL to 0.15L, what was its final pressure if it started at a pressure of 485 kpa
bija089 [108]

Answer:

2100 kPa

Explanation:

The temperature is constant, so the only variables are pressure and volume.

We can use Boyle’s Law.

p₁V₁ = p₂V₂     Divide both sides of the equation by V₂

p₂ = p₁ × V₁/V₂  

p₁ = 485 kPa; V₁ =              648 mL  

p₂ = ?;            V₂ = 0.15 L = 150 mL      Calculate p₂

p₂ = 485 × 648/150

p₂ = 2100 kPa
