which of the following would decrease the rate of a chemical reaction? adding more reactants stirring the reaction more vigorously squeezing the reactants into a smaller volume increasing the temperature raising the activation energy

Answers

Raising the activation energy would decrease the rate of a chemical reaction.

The rate of a chemical reaction refers to the speed at which the reactants are converted into products. There are several factors that can affect the rate of a chemical reaction, including the concentration of reactants, temperature, and the presence of catalysts or inhibitors.

Adding more reactants would generally increase the rate of a chemical reaction, as there would be more particles present to collide and react. Stirring the reaction more vigorously would also increase the rate of the reaction, as it would increase the chances of successful collisions between reactant particles. Squeezing the reactants into a smaller volume would also increase the rate of the reaction, as it would increase the concentration of reactants and the chances of successful collisions.

On the other hand, increasing the temperature would generally increase the rate of a chemical reaction, as it would increase the kinetic energy of the reactant particles and increase the chances of successful collisions.

Most probably the reaction 2 could be A: "( 2NO(g)+O2(g)→2NO2(g) )".

Reaction 2 is the second step of the overall reaction, which is the formation of NO2 from NO and O2. The overall reaction is (2O3(g)+2NO(g)→2NO2(g) + 2O2(g) ).

From the given options, the best match for reaction 2 is  (NO(g) + O2(g) → 2NO2(g) ) because it is a balanced equation that forms 2 moles of NO2 from 1 mole of O2 and 1 m0le of NO. This is consistent with the balanced equation of the overall reaction, which forms 2 moles of NO2.

Option A: 2NO(g) + O2(g) → 2NO2(g) forms 2 moles of NO2 but it consumes 2 moles of NO which is not consistent with the overall reaction.

Option B: 5NO(g) + O2(g) → 3NO2(g) forms 3 moles of NO2 but it consumes 5 moles of NO, again this is not consistent with the overall reaction.

Option C: NO(g)+O2(g)→2NO2(g),  it is a balanced equation that forms 2 moles of NO2 from 1 mole of O2 and 1 m0le of NO.

control of metal-support interactions in heterogeneous catalysts to enhance activity and selectivity

Answers

Control of metal-support interactions (MSIs) in heterogeneous catalysts can enhance both activity and selectivity.

 

MSIs refer to the interactions between the metal catalyst and the support material it is placed on. By fine-tuning the MSIs, the activity of the catalyst can be increased by optimizing the distribution and dispersion of the metal particles. In addition, by controlling the MSIs, the selectivity of the catalyst can be improved, allowing for the production of specific products in a reaction. This is done by manipulating the electronic and geometric properties of the metal-support interface, which affect the adsorption and activation of reactant molecules.

In general, controlling MSIs is a powerful way to make heterogeneous catalysts work better.

Answers

The empirical formula of a compound with 7.8% carbon and 92.2% chlorine is CCl₄ and that of a compound with 10.0% C, 0.80% H and 89.1% Cl is CHCl₃.

In order to determine the empirical formula of the compounds, we have to divide the percentage by mass of each of the elements by their relative atomic masses and then divide them through the lowest ratio.

Carbon = 7.8%

7.8/12 = 0.65

Chlorine = 92.2%

92.2 / 35.5 = 2.59

Dividing by the lowest ratio,

Carbon  = 0.65/0.65 = 1

Chlorine = 2.59/0.65 = 3.98 ≅ 4

So the empirical formula is CCl₄.

Hydrogen = 0.80%

0.80/1 = 0.80

Chlorine = 89.1%

89.1/35.5 = 2.50

Carbon = 10.0%

10/12 = 0.83

Dividing by the lowest ratio,

Hydrogen = 0.80/0.80 = 1

Carbon = 0.83/0.80 = 1.03  ≅ 1

Chlorine = 2.50/0.80 = 3.1  ≅ 3

A scale in Kelvin is absolute. There are no degree symbols after its values, which begin at absolute zero.

Both Celsius and Fahrenheit are relative scales. The degree symbol is used to indicate Fahrenheit and Celsius temperatures.

Given the temperature is 122°F

Temperature in Celsius is -

⇒ C = (F - 32)/1.80

⇒ C = (122 - 32) / 1.80

⇒ C = 90 / 1.80

C = 50°C

Temperature in Kelvin is -

Any material with a known composition is a chemical. To put it another way, a chemical always consists of the same "substance." There are some substances in nature, like water. Chlorine and other chemicals are made at factories.

What instances from chemistry?

All of these things are made of chemical, some natural and others synthetic, including air, water, iron, fuel, clothes, stone, equipment, plastics, plants, and food. Chemicals can be made up of several different chemicals or they can be specific chemical molecules like water. Ammonia, oxygen, water, carbon dioxide, and other substances are all present in air.

The density of air at ordinary atmospheric pressure and 25 ∘C is 1.19 g/L. What is the mass of the air in a room that measures 14.5×16.5×6.0 ft?

Answers

Answer:

40,827.34 g

Explanation:

First find the volume of the room and then multiply it by the density of air at ordinary atmospheric pressure and 25 ∘C.

In this case, the room has a length of 14.5 ft, a width of 16.5 ft, and a height of 6.0 ft.

volume = 14.5 ft x 16.5 ft x 6.0 ft = 1209.25 ft^3

To convert ft^3 to L, we can use the conversion factor 1ft^3 = 28.316846592 L

1209.25 ft^3 = 1209.25 * 28.316846592 = 34,416.99 L

Calculate the mass of the air in the room by multiplying the volume of the room by the density of air:

mass = 34,416.99 L x 1.19 g/L = 40,827.34 g

So, the mass of the air in the room is 40,827.34 g

Calculate the number of grams of sulfuric acid in 1 gallon of battery acid if the solution has a density of 1.31 g/ml and is 38.7 % sulfuric acid by mass.

Answers

Answer:

4.956 g/gallon * 0.387 = 1.91 g of sulfuric acid in 1 gallon of battery acid.

Explanation:

To calculate the number of grams of sulfuric acid in 1 gallon of battery acid, we can use the density of the solution and the percentage of sulfuric acid by mass.

First, we need to convert the density from g/ml to g/gallon. Since 1 gallon is equal to 3.785 L, we can multiply the density of 1.31 g/ml by 3.785 to get 4.956 g/gallon.

Next, we can use the percentage of sulfuric acid by mass to find the mass of sulfuric acid in the solution. To do this, we can multiply the mass of the solution by the percentage of sulfuric acid by mass, which is 0.387.

x consists of a flexible container with eight particles of a gas as shown. what happens to the pressure of the system when x is converted to the representations in (a), (b), and (c)?

Answers

When a gas is heated in a flexible container with constant pressure, the statement "The gas particles travel quicker" is accurate.

option (C)

The container's walls are struck more forcefully by the gas particles inside the container.

(a) Gas molecules lack a fixed form and a fixed volume. They grow till they fill their container. Gas molecules move readily both inside and outside of the container because they are fluid. Unless compressed, gas molecules are not very dense.

(b) Gas molecules mix and disperse as they diffuse and effuse (travel through small holes).

(c) The container's walls are struck more forcefully by the gas particles inside the container. The gas container's capacity expands as a result of the impact.

The carbon that is SP2 hybridized in the compound is carbon 4 (C4).

What is the hybridization?

When we talk about the hybridization of the carbon atom, we mean the fact that the orbitals that are in the carbon atom are mixed in such a way that the orbitals that have the appropriate energy to be able to participate in the chemical bonds are formed.

As such looking at the compound that we have been shown in the image, we can see that not all the carbon atoms would be at the same state of hybridization.
