Label the following as (I) increasing, or (D) decreasing the solubility of the carbon dioxide in a soft drink: Leaving the lid on the container (i. e. keeping the pressure high)

Removing the lid from the container

Keeping the container in the refrigerator

Warming up the liquid in the container

b. examine and describe cells

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.  

i think   the answer is c hope i'm right

gold is my favorite solid.
