HELP PLS I NEED HELP ASAP Chemical reactions occur around us every day. Combustion of hydrocarbons 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?

A. C4H10+ O2→CO2+ H2O

B. CO2+ H2O →C6H12O6+ O2

C. CaCO3+ HNO3→Ca(NO3)2+ H2O + CO2

D. NaHCO3+ HC2H3O2→NaC2H3O2+ H2O + CO2

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

the answer would be c

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

pv=nrt
