Theoretical yield is the quantity of a product obtained from the complete conversion of the limiting reactant in a chemical reaction. It is the amount of product resulting from a perfect chemical reaction and thus not the same as the amount you'll actually get from a reaction.

Answer:

We have the final answer as

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual density = 5.6 g/mL

error = 5.6 - 5.2 = 0.4

The percentage error is

$P(\%) = \frac{0.4}{5.6} \times 100 \\ = 7.142857...$

Answer:

Similarity between photosynthesis and cellular respiration is that both process :

Involve production of energy

Exchange of gases

Goes through electron chain reactions

Explanation:

Photosynthesis : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

The electrons triggers the reaction of food formation.

Energy is released during photosynthesis.

Gaseous exchange between CO2 and O2 occur.

Respiration :

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

Exchange of Gases occur between organism and environment.

Here , mitochondrial electron transport occurs to produce ATP.

Hence , similarity between photosynthesis and cellular respiration is that both process:

Involve production of energy

Exchange of gases(carbon dioxide and oxygen)

Goes through electron chain reactions

Firlakuza [10]

Answer:

2.2mL

Explanation:

First, let us analyse what was given from the question:

C1 = 2.09M

V1 =?

C2 = 0.046M

V2 =100mL

Using dilution formula (C1V1 = C2V2), we can calculate the volume of the original solution as follows:

C1V1 = C2V2

2.09 x V1 = 0.046 x 100

Divide both side by the coefficient of V1 ie 2.09, we have:

V1 = (0.046 x 100) / 2.09

V1 = 2.2mL
