How many molecules are in 1200 g of acrylonitrile (C3H3N), a chemical used in the production of plastic
Help

Answers

Answer: [tex]136.2\times 10^{23}[/tex] molecules

Explanation:

According to avogadro's law, 1 mole of every substance contains avogadro's number of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}=\frac{1200g}{53.06g/mol}=22.62moles[/tex]

1 mole of acrylonitrile has = [tex]6.023\times 10^{23}[/tex] molecules

Thus 22.62 moles of  acrylonitrile has = [tex]\frac{6.023\times 10^{23}}{1}\times 22.62=136.2\times 10^{23}[/tex] molecules

Taking into account the definition of Avogadro's number, 1.36×10²⁵ molecules of C₃H₃N are in 1200 g.

Avogadro's Number

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Mass molar

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

This case

In this case, you know the molar mass of the elements is:

C= 12 g/moleN= 14 g/moleH= 1 g/mole

So, the molar mass of the compound C₃H₃N is calculated as:

C₃H₃N= 3× 12 g/mole + 3× 1 g/mole + 14 g/mole

Solving:

C₃H₃N= 53 g/mole

You have 1200 g of C₃H₃N. So, knowing its molar mass, you can calculate the number of moles that contain a mass of 1200 g as:

1200 g×[tex]\frac{1 mole}{53 grams} [/tex]= 22.64 moles

Then you can apply the following rule of three: If by definition of Avogadro's number 1 mole of C₃H₃N contains 6.023×10²³ molecules, 22.64 moles of C₃H₃N contains how many molecules?

amount of molecules of C₃H₃N= (22.64 moles × 6.023×10²³ molecules)÷ 1 mole

amount of molecules of C₃H₃N= 1.36×10²⁵ molecules

Finally, 1.36×10²⁵ molecules of C₃H₃N are in 1200 g.

From the question above, it can be seen that the oversized ears in bats is an adaptive features for them to get their food: as it helps them to use sound waves to detect the motion of their prey.

Unlike the bats, the rats adaptive features is to have a good running legs. This will help them to avoid getting eating by predators.

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?

2SO2(g) + O2(g) → 2SO3(g)

A) NO increases the rate at which SO3 molecules are formed.

B) NO reacts with SO3 to produce more SO2 molecules.

C) NO decreases collisions between the SO2 and O2 molecules.

D) NO increases the concentration of the SO2 and O2 molecules.

E) NO increases the activation energy of the SO2 and O2 molecules.

Answers

Answer: A) NO increases the rate at which [tex]SO_3[/tex] molecules are formed.

Explanation:

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.

[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]

Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among [tex]SO_2[/tex] and [tex]O_2[/tex] molecules will incraese which in turn will lead to formatioon of more [tex]SO_3[/tex] molecules.

Answer:

A) NO increases the rate at which  molecules are formed.

What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?

Answers

Answer:

Electric Current

Explanation:

The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit.  Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.

Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.

Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.

The yellow arrow in the diagram shows the flow of electrons.

Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.

Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.
