Answer:

Option C. Silver is a catalyst in this reaction.

Explanation:

From the question given, we discovered that the addition of silver in the reaction between ethene and oxygen produces epoxyethane at a much faster rate. This simply means that silver act as a catalyst in this reaction.

A catalyst is substance that increases the rate of a reaction without itself taking part in the reaction. The catalyst creates an alternate path way by lowering the activation energy so that the reaction can proceed at a much faster rate.

Since the addition of silver makes reaction to occur at a much faster rate, it therefore means that silver act as a catalyst in the reaction.

Question 8 (1 point)
Margaret [11]

Combustion of Fossil Fuels

Explanation:

The combustion of fossil fuels is a major contributor to unbalancing of the carbon cycle which causes more carbon dioxide to be released into the air than can be naturally processed.

Combustion of fossil fuel is an anthropogenic source of carbon dioxide emission. This chemical process is used to power internal combustion engines and industrial activities. The by product is usually carbon dioxide.

Plants that use carbon dioxide for their life processes cannot completely absorb all of this anthropogenic emission.

Naturally, animal respiration and decomposition provides enough carbon dioxide for use during photosynthesis. Combustion of fossil fuels tips this balance.

The standard biological reaction Gibbs energy for the removal of the phosphate group from adenosine monophosphate is 14 kJ mol-1
nignag [31]

Answer: K = 284

Explanation:

Gibbs free energy (DG) = RT(InK)

Where :

R = Gas constant = 8.314J/K/mol = 0.008314KJmol/K

T = temperature in Kelvin = 298K

K = dissociation rate

DG = 14

DG = RT(InK)

14 = 0.008314 × 298 × (InK)

14 = 2.477572 × InK

Ink = (14 ÷ 2.477542)

InK = 5.6507619

K = 284

for the substituted cyclohexane compound shown, identify the atoms that are trans to the bromo substituent.
hodyreva [135]

Substituents are trans to each other if the appear on opposite sides in the structure. C, E, G, H and K are trans to the bromo substituent.

The substituted cyclohexane compound is shown in the image attached. Two substituents in a compound are trans to each other if they appear on opposite sides of the structure. Cis substituents appear on the same side of the structure.

Considering the structure as shown in the image attached, the substituents that are trans to the bromo substituent are the substituents shown as letters C, E, G, H and K. They lie opposite to the bromo substituent.
