Explanation: A thermochemical equation is a balanced chemical equation which require an enthalpy change.
A balanced equation is the equation in which number of atoms on reactant side is same as the number of atoms on product side.
A thermochemical equation for is:
Here, heat is released in the reaction hence, it is a type of exothermic reaction.
A thermochemical equation for is:
Here, heat is absorbed in the reaction hence,it is a type of endothermic reaction.
I feel like it would be O.40 mol Mgo but I could be wrong
Answer:
B. Add more chloride ions
Explanation:
Because we know based on lechatlier that any disturbance to equilibrium will make the shift act accordingly. If something is removed it wants to shift to side where it is removed to compensate for the change, if something is added it wants to move away from it to minimize the change.
Therefore, if you add chloride ions, the equilibrium shifts to left to make more solid lead chloride.
Methane is CH4
Ethane is. C2H6
Method by ☆cracking alkanes☆
In this case, by cracking methane
Cracking alkanes is the method used to split a long alkane structure into smaller alkanes using high temperature and a catalyst.
e.g. C2H6 -> CH4 + CH2
