The reaction between carbon monoxide and water is given below: CO(g) + H2O(l) CO2(g) + H2(g) We therefore know that which of the following reactions can also occur? CO2(g) + H2(g) CO(g) + H2O(l) CO(g) + 3 H2(g) CH4(g) + H2O(g) CH4(g) + H2O(g) CO(g) + 3 H2(g) None of the Above

Following reactions can also occur :-

   (Forward reaction)

   (Backward reaction)

Explanation:

As the given reaction is as follows.

This is a forward reaction which can also be written as follows.

     (Backward reaction)

This carbon monoxide when chemically reacts with newly formed hydrogen gas then it will lead to the formation of methane and water as follows.

    (equilibrium)

Hence, these reactions can be written as follows.

     (Forward reaction)

   (Backward reaction)

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
