Which of the following reactions would not have an increase in entropy? a. caco3 (s) → cao (s) + co2 (g) b. co2 (s) → co2 (g) c. 4 c3h5n309(1) ► 6 n2 (g) + 12 co2 (g) +10 h20 (g) +o2 (g) d. oz(g) + 2 h2(g) → 2 h20 (g) e. more than one correct answer present.

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.  

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl
