QUESTION 54 What is/are the reactant(s) of the chemical reaction shown?
CH4 (g) + 202 (g) → CO2 (g) + 2H20 (g)
O CH4 only
O 02 only
O CH4 and 02
O CO2 and H20
The process above is not a chemical 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.  

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
