Answer:
25%.
Explanation:
The following data were obtained from the question:
Experimental yield = 30 g
Actual yield = 40 g
Percentage error =..?
Thus, we can calculate the percentage error as follow:
Percentage error = |Experimental – Actual | / Actual × 100
Percentage error = |30 – 40|/40 × 100
Percentage error = 10/40 × 100
Percentage error = 25 %
Therefore, the percentage error in calculating the yield is 25%

Explanation:
In a double replacement reaction occurs a new combination of the species present in the reactants
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
A balanced chemical equation always follows this law.
For the given chemical reaction, the balanced equation follows:

This is considered as neutralization reaction because an acid reacts with a base to produce a salt and water.
Hence, the balanced chemical equation is written above.
Man this answer could be so dark
The amount of reflected sunlight varies. There really isn't any such thing as moonlight. The light we perceive to be produced by the moon is really just sunlight! As the moon moves around the planet, we can see differing amounts of reflected light that we categorize as phases.
