6. The following reaction occurs under standard conditions: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
a. Which bonds are broken and which are formed during the reaction? (1 point)

b. Determine the enthalpy of the reaction. (2 points)

a. CH4 → CO2 and H20

O2 → CO2 and H20

b. -890 kJ

Explanation:

imma come back to you hold on

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).
