I will solve the question assuming the reaction used as below
1 CH4(g) + 1 H2O(g) ==> 1 CO(g) + 3 H<span>2(g)
In the reaction, CH4 is the reactant and CO is the wanted product. If you look at the coefficient of the substance, for every 1 mol of CH4 react there will be 1 mol of CO produced. So, if you have 7 moles of CH4 the amount of CO produced would be: 7 moles * 1/1= 7 moles of CO</span>
Answer:
Explanation:If 5.51 g of water needs 645 J of energy to warm then 55.1 g of water needs 6450 J of energy to warm.
Answer:
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
Every chemical reaction requires a minimum amount of energy to undergo reaction.
The total energy required is Threshold energy. The chemicals have some internal energy and they require some extra energy which is known as activation energy.
The reaction occurs when two molecules or atoms come closer to each other and for this they need kinetic energy.
Now for an effective collision the two molecules or atoms should collide with a minimum amount of energy so that they may undergo reaction so again they need some energy
These kinetic energy and energy for effective collision is actually called as activation energy.
