What happens in the artificial transmutation of an element? Included an example.

Answers

Answer 1
Answer:

Answer:

Explanation:

In an artificial transmutation, atoms of one element are artificially made to strike other particles with in an accelerator. Usually in an Artificial transmutation, there are particle accelerators that bombard the elements with in them using alpha particles, deuterons etc.  

This bombarding causes lodging of certain elements into the targeted nucleus, thereby forming a new and a different element.  

For example -

In the first artificial transmutation, Helium nucleus was bombarded on nitrogen nucleus thereby producing new nuclei and a proton.

Answer 2
Answer: In an artificial transmutation an element is transformed into another element by being shot by another element or particle. For example if you shoot an alpha particle like Helium at Nitrogen then you transform the Nitrogen into an oxygen and you get Hydrogen as a By-product

Consider this equilibrium:CO2(g) + 2H2O(g) CH4(g) + 2O2(g).

What indicates that the reactants are favored?

Keq is zero.
Keq is very large.
Keq is slightly less than 1.
Keq is slightly greater than 1.

Answers

The equilibrium constant is a value which represents the equilibrium of a reaction. It is a reaction quotient when the reaction reached equilibrium. If Keq is greater than 1, the mixture contains mostly the products. On the other hand, if Keq is less than 1, the mixture contains the reactants. Therefore, the answer is the second option, Keq is very large.

Why do we crack molecules?

Answers

We need to crack molecules in order for us to get the desired molecule. For example, in the extraction of crude oil, after entering the fractional distillation, it will give products base on their molecular structure. The products are gasoline, diesel fuel, jet fuel, wax, asbestos,kerosene.
cracking is the process whereby complex organic molecules such as kerogens or long chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons,. 
it is done to get more important substances

Besides water, what is the product of a Neutalization Reaction between HClO3 and Sr(OH)2?a. SrClO3
b. Sr-1(ClO3)+2
c. Sr2CIO3
d. Sr(ClO3)2​

Answers

Answer:

The answer to your question is letter d. Sr(ClO₃)₂

Explanation:

Data

Reactants   HClO₃ and Sr(OH)₂

This is a neutralization reaction because the reactants are a base (Sr(OH)₂) and an acid (HClO₃).

The products in a neutralization reaction are always water and a salt.

Balanced chemical reaction

           Sr(OH)₂  +  HClO₃  ⇒  H₂O  +  Sr(ClO₃)₂
