Answer:
75.0%
Explanation:
Data obtained from the question. This includes the following:
Actual yield = 6.13g
Theoretical yield = 8.17g
Percentage yield =...?
The percentage yield can be obtain by using the following formula:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 6.13/8.17 x 100
Percentage yield = 75.0%
Therefore, the percentage yield of water from the reaction above is 75.0%
The law of conservation of energy states that energy cannot be created or destroyed but can be converted or transferred. So when you're eating a burger which has chemical energy, it is transferred to mechanical energy if you go out and ride a bicycle. Another example is when the Sun which is thermal energy shines on the apple tree, it is converted to chemical energy because the apple has chemical energy. Transferred is pretty similar.
The Chemical reactivity of metals varies with your eletropositividade, so the more eletropositivo is the most reactive element is metal. The most reactive metals are those that have great tendency to lose electrons and therefore form positive ions with more ease.
hope this helps!
Answer:
In classical theories of gravitation, the changes in a gravitational field propagate. A change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces.
