Answer and Explanation:

The primitive atmosphere of Earth may have favored the abiotic synthesis of organic molecules because it **had close to no oxygen, hence, it was powerfully reducing. It had pure energy sources too in form of ultraviolet rays from the sun (it was extremely hot! Too hot for water in liquid form to exist in fact!), outgassing from the numerous volcanoes and lightning**.

Abiotic synthesis means a formation reaction where the reactants are charged to become products, almost all on their own, with no catalyst especially.

So, these factors would have helped the organic molecules to form as most of what is needed to overcome the energy barrier and become products.

What type of reaction is Mg + Cl^2>MgCl^2

Paul [167]

Answer:

Synthesis.

Explanation:

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

For example:

Mg + Cl₂ → MgCl₂

when magnesium combine with chlorine it form magnesium chloride.

Magnesium is alkaline earth metal and present in group two. Magnesium has two valance electrons. Magnesium atom loses its two electron to complete the octet. Chlorine is halogen element and have seven valance electrons. Chlorine needed one electron to complete the octet. When it combine with magnesium atom it accept the two electrons from magnesium atom that's why two chlorine atoms are combine with one magnesium atom to make the compound neutral.

What is the effect of an increase in the average kinetic energy of an object

timofeeve [1]

The effect of an increase in the average kinetic energy of an object would be an increase in the temperature of the object. Temperature is directly proportional to the average kinetic energy of the molecules in the object. Hope this answers the question.

The nucleoside adenosine exists in a protonated form with a pKa of 3.8. The percentage of the protonated form at pH 4.8 is close

Natasha_Volkova [10]

Answer:

Ok:

Explanation:

So, you can use the Henderson-Hasselbalch equation for this:

pH = pKa + log( $A^-/HA$ ) where A- is the conjugate base of the acid. In other words, A- is the deprotonated form and HA is the protonated.

We can solve that

1 = log( $A^-/HA\\$ ) and so 10 = $A^-/HA$ or 10HA = A-. For every 1 protonated form of adenosine (HA), there are 10 A-. So, the percent in the protonated form will be 1(1+10) or 1/11 which is close to 9 percent.
