Answer: Option (D) is the correct answer.

Explanation:

A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.

As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, morr collisions occur due to which there is rapid formation of products.

Thus, we can conclude that statement the reaction is completed in a shorter amount of time, best describes the result of using a catalyst in a chemical reaction.

The danger from radon gas would most likely be greatest in:.

Semmy [17]

The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.

<h3>What is radon gas?</h3>

Radon is a naturally radioactive gas generated from different elements such as uranium or radium.

Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.

Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.

Two jars are placed inside an insulated box. One jar contains ice water and the other contains hot soup. What will happen to the

pickupchik [31]

Answer is: the hot soup will lose heat and the ice water will gain heat.
Heat spontaneously flows from a hotter to a colder body.
The thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter (in this case from the hot soup to the cold water).

How many moles of glucose can be produced

Arturiano [62]

Answer:

moles of glucose

2.3166 moles of glucose

Explanation:

The balance reaction for the formation of glucose is :

$6CO_{2}+6H_{2}O\rightarrow C_{6}H_{12}O_{6}+6O_{2}$

here , CO2 = carbon dioxide

H2O = water

C6H12O6 = glucose

O2 = Oxygen

According to this equation :

6 mole of CO2 = 6 mole of H2O = 1 mole of C6H12O6 = 6 mole of O2

We are asked to calculate the mole of Glucose from carbon dioxide.

So,

6 mole of CO2 produce = 1 mole of C6H12O6

1 mole of CO2 will produce =

$\frac{1}{6}$ moles of glucose

13.9 moles of CO2 will produce :

$\frac{1}{6}\times 13.9$

=2.3166 moles of glucose

Note : first , Always calculate for one mole (By dividing)

. After this , multiply the answer with the moles given.

Always write the substance whose amount is asked(glucose) to the right hand side
