The concentration of reactants and products and the rate of reaction were measured during a chemical reaction. After the first 3 seconds, the rate of reaction was 1.8 x10−6 M/s. Which of the following would explain a lower rate after another 3 seconds?

A - The concentration of reactants increased while the concentration of product decreased.
B - The concentration of reactants decreased while the concentration of product increased.
C - All concentrations of reactants and products decreased.
D - All concentrations of reactants and products increased.

Answers

Answer 1

Answer:

B

Explanation:

During the first half of the reaction there was an increase in the rate of reaction due to the high concentration of the reactants. But as the reaction continues we witness a decrease in the amount of reactants which lowers the rate.

Answer 2

Answer:

B.  The concentration of reactants decreased while the concentration of product increased.

Explanation:

took the test :)

The characteristics of a certain gas are listed in the table.

What is the expected density of the above sample of gas?
A - 3.16 g/L
B - 1.58 g/L
C - 1.21 g/L
D - 1.03 g/L

Answers

Answer:

Option A. 3.16 g/L

Explanation:

We'll begin by calculating the molar mass of Cl₂. This can be obtained as follow:

Molar mass of Cl₂ = 2 × 35.45

= 70.9 g/mol

Finally, we shall determine the density of Cl₂. This can be obtained as follow:

Molar mass of of Cl₂ (M) = 70.9 g/mol

Pressure (P) = stp = 1 atm

Temperature (T) = stp = 273 K

Gas constant (R) = 0.0821 atm.L/Kmol

Density (D) =?

D = PM / RT

D = (1 × 70.9) / (0.0821 × 273)

D = 70.9 / 22.4133

D = 3.16 g/L

Thus, the density of the gas is 3.16 g/L.

Answer in detail?? What precautions would you take to protect yourself from an earthquake, when you are at home and when you are outdoors?

Answers

Answer:

If you're indoors, stay inside. If you're outside, stay outside. If you're indoors, stand against a wall near the center of the building, stand in a doorway, or crawl under heavy furniture (a desk or table). Stay away from windows and outside doors.

Answer

Protect your head and neck with a large book, a pillow, or your arms. The goal is to prevent injuries from falling down or from objects that might fall or be thrown at you.If you are able, seek shelter under a sturdy table or desk. Stay away from outer walls, windows, fireplaces, and hanging objects.If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows.If you are outside, go to an open area away from trees, telephone poles, and buildings, and stay there.

The graph shows the change in concentration of one of the species in the reaction
A + B + C→D.

If the graph indicates the reaction rate, then the concentration of which species is plotted?

A

Answers

Answer:

its D

Explanation:

Took the test

The specie whose concentration is plotted is D. The rate of reaction is how quickly or slowly hat a reaction proceeds.

Rate of  reaction

The term rate of reaction refers to how quickly or slowly hat a reaction proceeds. A reaction rate plot involves the concentration of the species plotted against time.

Now we can see from the plot that concentration is increasing with time. Since the concentration of products increases with time, then the specie whose concentration is plotted is D.

pls tell the answer fast ​

Answers

Answer:

The correct answer is - D C2H4.

Explanation:

Saturated hydrocarbons are hydrocarbons with single covalent C-C bonds. They are known as alkanes. The general formula for these hydrocarbons is  CnH2n+2

Unsaturated hydrocarbons the hydrocarbons with double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is  CnH2n and CnHn-2

For the given options:

Option D: C2H4, is the simplest alkene with a double bond so it is an unsaturated hydrocarbon.

What is the activation energy of this reaction? (5 points)

Answers

Answer:

the activation energy is 65-30

35

The activation energy of this reaction is 35 kJ.

What is activation energy?

Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.

The activation energy is equal to the difference between the threshold energy needed for the reaction and the average kinetic energy of all the reacting molecules.

The activation energy of a reaction is the difference in energy between the threshold energy and energy of the reactants.

Given,

The highest energy for a reaction to happen = Threshold energy = 65 kJ

Energy of the reactants = 30 kJ

Therefore, The activation energy of this reaction is 35 kJ.

a reaction without a catalyst. Which graph shows the energy of the same
reaction with a catalyst?

Answers

Answer:

D.

Explanation:

Catalysts are substances that increase the rate of a reaction i.e. make it faster. Catalysts do this by reducing the activation energy needed for a reaction to occur.

According to the image in this question, a graph showing the energy of a reaction without a catalyst is displayed. This means that a longer time will be spent. However, with a catalyst, the activation energy will reduce as seen in the image in option D.

Balance the reaction and determine which of the following coefficients

Answers

Answer:

B. The correct ratio is 3:1:1:3

Explanation:

According to this question, the following chemical equation was given:

CH3COOH + Al(OH)3 → Al(CH3COO)3 + H2O

This equation is obviously not balanced because the number of atoms of each element on both sides of the equation is not equal or the same. To balance the equation, we make use of coefficients as follows:

3CH3COOH + Al(OH)3 → Al(CH3COO)3 + 3H2O

- There are now 6 moles of C on each side

- There are now 15 moles of H on each side

- There are now 9 moles of O on each side

- There is now 1 mole of Al on each side

The correct ratio of each compound is in the order 3:1:1:3
