Chemical reactions occur around us every day. Combustion releases the carbon stored in fossil fuels (e. g. coal, oil, natural gases) into the atmosphere as carbon dioxide gas.
Which of the following equations represent this process?
O NaHCO 3 + HC2H302 - NaC 2H 302+H2O + CO2
o CaCO 3 + HNO 3 - Ca(NO3)2 + H2O + CO2
O C&H 10 + 02 – CO 2 + H20
O CO 2 + H20- C6H 1206+ O2

explanation:

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
