Answer:
Number of moles = 0.075 mol
Explanation:
Volume = 500.0 mL = 0.5 (Converting to L by dividing by 1000)
Molarity = 0.15 M
Number of moles = ?
The relationship between the quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Molarity * Volume
Number of moles = 0.15 * 0.5
Number of moles = 0.075 mol
The correct answer to this question is letter "B) 8.4 × 10-4 M."
2CO+O2<->2CO2
-x -x +x
It started as 2CO2 so +x, then it decomposed into 2CO and O2, so-x
2CO-oxidized, O2-Oxidized, 2CO2-reduced
the easiest way is to look at the equation, so if we have some reactant and no product
A<->2C+D
-x +2x +x
so if we had product concentration, and no reactant concentration
3A<-> C+D
+3x -x-x

Answer:
condensation reaction
Explanation:
In condensation reaction is a small molecule formed from the atoms removed from a single reactant molecule
Answer:
Explanation:
Hello!
In this case, according to the given chemical reaction, it is possible to calculate the enthalpy change of the reaction via:
Since the enthalpy of formation of oxygen is 0. Thus, given the enthalpies of formation of gaseous carbon dioxide and water, we obtain:
Best regards!
Electrons per shell: 2, 8, 5
