The atom is krypton and its symbol is Kr.
the mass number is 41 + 36 = 77
its charge is 0 as it is a noble gas.
Chromium has a positive charge (it's a multivalent metal with multiple positive charges)
Carbonate has a negative charge (-2)
Chromium would be the cation, and carbonate would be the anion.
The answer would be ammonium: NH4+ (C.)

Answer:
Mass of CO2 WILL BE ~ 9.33 g
Explanation:
Moles of O2 = 14/18
Let the mass of CO2 be x
Then moles of CO2 will be = x/12
moles of CO2 = moles of O2
x/12 = 14/16
x = 9.33 grams
