Consider the results you observed in reaction 8.1. What would you expect to happen to the total observed temperature change if you doubled the mass of the
sodium bicarbonate and the volume of vinegar? Explain this on a molecular level.

i'm not sure

explanation:

i'll try whatever you got

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

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.
