Answer: a) 49.8 gram
b) 47.0 %
Explanation:
First we have to calculate the moles of glucose

The balanced chemical reaction will be,

From the balanced reaction, we conclude that
As,1 mole of glucose produce = 2 moles of ethanol
So, 0.54 moles of glucose will produce =
mole of ethanol
Now we have to calculate the mass of ethanol produced


Now we have to calculate the percent yield of ethanol

Therefore, the percent yield is 47.0 %
Answer:
Arrow.
Explanation:
Hello!
In this case, since chemical reactions are characterized by the presence of some species at the left on an arrow representing the reactants and at the right the products, we understand that the arrow, separating reactants and products is understood as "produces" or in very chemical words "yields"; therefore, the symbol that takes the place of the word yields is an arrow.
Best regards!
Answer:
Take a look at the attachment below
Explanation:
Take a look at the periodic table. As you can see, Rubidium is the closest element to Cesium, and happens to have the closest boiling point to Cesium, with only a difference of about 30 degrees.
Respectively, you would think that fluorine should have the least similarity to Cesium with respect to it's boiling point, considering it is the farthest away from the element out of the 4 given. This is not an actual rule, there are no fixed trends of boiling points in the periodic table, there are some but overall the trends vary. However in this case fluorine does have the least similarity to Cesium with respect to it's boiling point, a difference of about 1,546.6 degrees.

The density is calculated with the following formula:
density = mass / volume
If there is water on the pan of scale, you will read the mass of the mineral plus mass of water.
Using this value to calculate the density (ignoring the fact that you had water) you will obtain a higher density of the mineral than the real one.
