Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. use enthalpy of formation data to calculate the number of moles of co2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions (1 atm and 25 �c).
each must be in mol * mj^-1
(a) coal, c(s, graphite)
(b) natural gas, ch4(g);
(c) propane, c3h8(g);
(d) octane, c8h18(l) (? hf� = �250.1 kj �mol^�1).

i dont know

explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

i think its 100.

hope this !
