Calculate the volume in milliliters of a solution required to provide 2.14 g o sodium chloride from a 0.930 M solution.

Answers

Answer 1

Answer:

Step 1 of 3

Here we have to calculate the volume of the solution in mL.

(a) 2.14 g of sodium chloride from a 0.270 M solution

We can calculate the volume of a solution from its molarity. It is known that the molarity of a solution can be calculated as follows,

Molarity = 

Hence volume of solution = 

Here it has been given that,

Mass of NaCl = 2.14 g

Molarity = 0.270 M

Molecular weight of NaCl = 58.44 g/mol

In order to calculate the volume, 1st we have to find out the number of moles,

Number of moles of NaCl = 

                                     =     = 0.03662 mol of NaCl

Now the volume can be calculated as,

volume of solution = 

               =    = 0.136 L or 136 mL solution

Hence the volume of NaCl is found to be 136 mL.

CaCO3 → CaO + CO2

Which statement is true?

A. Both are synthesis reactions.
B. Both are decomposition reactions.
C. A is a synthesis reaction, and B is a decomposition reaction.
D. A is a decomposition reaction, and B is a synthesis reaction.

Answers

In the given chemical reactions, the statement that is true is A synthesis reaction, and B is a decomposition reaction. The correct option is C.

What are synthesis and decomposition reactions?

Synthesis reactions are those reactions in which two reactants combine to form a single big product or compound. Like the first one reaction in which the magnesium and oxygen combine to create two moles of magnesium oxide. A + B = AB. When

Decomposition reactions are those reactions in which one reaction or compound breaks down to comprise two smaller products. Like the second reaction, calcium chloride breaks down into calcium oxide and carbon dioxide. AB = A + B.

Thus, the correct option is C. A is a synthesis reaction, and B is a decomposition reaction.

What is the percent yield if 23.1 grams of FeCl3 (162.2 g/mol) is created from 10.61 grams of iron (55.85 g/mol) in the following reaction Report your answer with three significant
figures
2 Fe + 3Cl2 + 2 FeCl3

Answers

Similar question just through and use it to answer your. Thanks. Hope it helps.

The percentage yield of the reaction if 23.1 grams of FeCl₃ is created by 10.61g of Fe is 74.9 %.

What is percent yield?

Percent yield of a reaction is the ratio of actual yield to the theoretical yield multiplied by 100.

As per the given balanced reaction, one mole or 55.85 g of Fe is needed to produce 1 mole or 162.2 g of FeCl₃.

Then theoretically, the mass of FeCl₃ which can be produced by 10.61 g of Fe is calculated as follows:

= (10.61 × 162.2) / 55.85

=30.81 g

This is the theoretical yield.

The actual yield is given 23.1. Now the percentage yield is calculated as follows:

Percentage yield = (Actual yield/ heretical yield)×100

                             = (23.1/30.81)×100

                             = 74.9 %.

Hence, the percentage yield of the reaction is 74.9 %.

The total pressure in a mixture of gases is equal to the partial pressure(s) of ________. the gas that occupies the largest volume the gas with the smallest number of moles all the gases added together the gas with the highest molecular weight the gas with the greatest number of moles

Answers

The total pressure in a mixture of gases is equal to the partial pressure of all the gases added together

According to Dalton's Law of Partial Pressure,  The total pressure exerted by a mixture of gases which are non reacting is equal to the sum of the partial pressure of each individual gas that make up the mixture

Mathematically, Ut can be written as

P{total}= p1+p2, ....+ pn

where p1, p2, …, pn are partial pressures of each gas component.

For example :A gaseous mixture consisting of Helium and Nitrogen gas . If the pressure exerted by He is 3 atm while Nitrogeb exerted is 9 atm. The total pressure will be:

P{total}= p1+p2, ....+ pn

P{total}= 3+9

P{total}= 12

It may be difficult to tell when a story took place, unless an author explicitly states it, but the presence or absence of technology can help a reader make an approximate guess as to when the story was set. Only novels and short stories that were written very recently will include references to smartphones and apps. Storylines that include references to the internet were written within the past 25 years. If a story makes mention of a television, then it probably took place during or after the 1950s. The modes of transportation that people take are more examples of technology that can help the reader determine roughly when the story took place. If a character takes a plane ride, then the story very likely took place after World War II because commercial air travel became popular after the war. A character riding in a car wouldnt happen before the 1900s. Of course, if the story mentions more recent advances like power windows or a driverless car, then it is far more recent. Train travel would put the setting within the past 200 years. The absence of technology doesnt always mean that the story took place hundreds of years ago, it could just mean that mentioning technology was not necessary to tell the story. The use of planes in World War II helped create the commercial air travel industry.Authors always include references to technology when they are writing about recent events.Stories that mention smartphones are not very popular.
