Answer:
The activation energy of a chemical reaction is the energy that is required to be supplied for a chemical reaction to take place. The activation energy for the reaction of sodium is low compared to the energy released such that the reaction of sodium and water is spontaneous resulting in the melting of the sodium into liquid form
The activation energy of a candle wax is much higher, requiring the ignition of the wick which burns and in turn melts the candle wax to release vapors that burns alongside the wick to produce sooth carbon dioxide, carbon monoxide and water vapor and release of heat energy which also fuels further combustion of the candle wax and wick
Therefore, the activation energy of the candle wax and wick which require the heat of direct flame from an ignited matches is higher than the activation energy of sodium placed in a medium of water that reacts spontaneously without heat application
Explanation:
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the volume of the new solution by using the general formula of dilution:
In such a way, we solve for the final volume, V2, to obtain:
Regards!
Answer:
True
Explanation:
True because of the law of conservation of mass, the same same amount of atoms will be on both sides of the reaction.
The correct answer to this question would be heat energy
The primary distinction between the digestive systems of cows and humans is that the former uses a foregut fermenter while the latter uses a straightforward monogastric digestion. The types of teeth, mouths, stomachs, guts, and digestive enzymes released by the gut also vary between the two digestive systems. Cows and humans have different digestive systems because they have evolved two different sorts of dietary patterns based on their capacities. The primary distinctions between the digestive systems of cows and humans are in the types of teeth, mouths, stomachs, and intestines, as well as the enzymes released.
