The prefix mili-means a thousand
OLEGan [10]
<h2>Answer:</h2>

<em>Given data:</em>

1 kilogram = 1,000 grams

how many kilograms is 1,216 grams?

<em>Solution:</em>

1000 grams = 1 kilogram

1 gram = 1/1000 kilograms

1216 grams = 1/1000 * 1216 = 1.216 kilograms.

                                                    <em> Hence 1216 grams =  1.216 kilograms.</em>

The reaction between C2H6 and Cl2 is by addition
igomit [66]

The reaction between C2H6 and Cl2 by addition is C2H4Cl2 or dichloroethane. It must be under the presence of sunlight because halogen such as chlorine cannot easily react with the sigma bond of alkane such as ethane.

True or false high temperatures reduce activation energy
astra-53 [7]

Answer:

False.

Explanation:

Activation energy ΔGₐ is only directly affected by the shape of the reaction coordinate curve, and is a function of kinetics.

Activation energy ΔGₐ is the minimum amount of energy needed to overcome the process of the reactant into the transition state, and finally the product. Reaction coordinate diagrams are purely based on potential energy of the molecules (electronic structure).

The <em>rate</em> at which the reaction will occur may change due to high temps, but not the actual ΔGₐ. To better understand, look at the Arrhenius equation. Ea (activation energy) is a constant, and is not affected by temperature changes. The rate constant k is only affected by temperature change.
