Explanation:

To graph the function g(x) = f(-x), you can start with the graph of f(x) and then reflect it about the y-axis.

To find the graph of the function g(x) = f(-x), we can start with the graph of the function f(x) and then reflect it about the y-axis.

If the graph of f(x) is symmetric with respect to the y-axis, meaning it is unchanged when reflected, then g(x) = f(-x) will have the same graph as f(x).

However, if the graph of f(x) is not symmetric with respect to the y-axis, then g(x) = f(-x) will be a reflection of f(x) about the y-axis.

In either case, the resulting graph of g(x) = f(-x) will be symmetric with respect to the y-axis.

Answer: A

Explanation:

The -ane suffix implies that the compound has only single bonds for carbon-carbon bonds. The but- prefix implies that the compound consists of four carbons. Since 4 bonds are required for each carbon, there will be a total of 10 hydrogen atoms: 3 on each carbon at the end of the chain and 2 for each carbon in the middle of the chain. Thus, butane is A.

Answer

172 g/mol

Explanation

The chemical formula of copper I carbonate is Cu₂CO₃

Using the given molar masses of:

Cu = 56 g/mol

C = 12 g/mol

O = 16 g/mol

The molar mass of Cu₂CO₃ = (2 x 56 g/mol) + 12 g/mol + (3 x 16 g/mol)

Cu₂CO₃ = 112 g/mol + 12 g/mol + 48 g/mol

Cu₂CO₃ = 172 g/mol

The concentration mass by volume percent of a solution is 2 %

What is mass by volume percent of a solution ?

The ratio of the mass of the solute present in a solution to the volume of the solution as a whole is known as the mass/volume percent. The given proportion must be multiplied by 100 because this type of concentration is expressed as a percentage, as shown below.

Mass/Volume Percent is calculated as follows:

mass (solute(g)) / Volume(solution(mL) x 100

Given that:-

Mass of solute =50g

Volume of solution =2.5L = 2500mL

As we know that, mass by volume percentage of the solution is given by-

Mass by volume %=  mass of solute/Volume of solution *100

                                = 50/2500*100 = 2 %

The concentration mass by volume percent of a solution is 2 %

Explanation:

edge 2022

The inside of a basketball has a pressure of 0.476 atm at 25.0°C. The pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.

The term pressure is defined as the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P.

There are two basic types of pressure are absolute and gauge - distinguished by what pressure they are compared to, which is called the reference pressure.

Given:

P1 = 0.476 atm

T1 = 25.0°C = 298K

P2 = ?

T2 = 20.0°C = 293 K

P1T1 = P2T2

By putting these values in above equation and we get,

P2 = P1T1/ T2

= 0.476 ×298 / 293

= 0.484 atm

Thus, the pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.

Answer:

antimony-121 has the highest percent natural abundance

Explanation:

percent natural abundance;

121.76 = 120.90 x + 122.90 (1 - x)

121.76 = 120.90 x + 122.90 - 122.90x

121.76 = -2x + 122.90

121.76 - 122.90 = -2x

x= 121.76 - 122.90/ -2

x= 0.57

Where x and 1 - x refers to the relative abundance of each of the isotopes

Percent natural abundance of antimony-121 = 57 %

Percent natural abundance of antimony-123 = (1 - 0.57) = 43%

Let us remember that isotopy refers to a phenomenon in which atoms of the same element have the same atomic number but different mass numbers. This results from differences in the number of neutrons in atoms of the same element.

We can clearly see that antimony-121 has the highest percent natural abundance.

The data that would demonstrate the action of photosynthesis is:

"When the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 ppm."

This data shows a decrease in carbon dioxide concentration from 800 to 600 ppm when a plant is exposed to light. During photosynthesis, plants absorb carbon dioxide from the surrounding environment and convert it into glucose and oxygen. The decrease in carbon dioxide concentration indicates that the plant is actively utilizing carbon dioxide for photosynthesis. As a result, the carbon dioxide level in the container decreases, demonstrating the action of photosynthesis. The other provided data points do not specifically indicate the action of photosynthesis. The first data point suggests that multiple plants in the container can prevent the carbon dioxide concentration from exceeding 1,000 ppm, but it does not indicate any decrease in concentration. The second data point mentions plants in darkness, which would not promote photosynthesis.

Reverse the second reaction and substract the the second reaction from first to get the reaction A + 1/2B  →  C and enthalpy change.

Enthalpy is a thermodynamic system's internal energy total as well as the volume times pressure ratio. Enthalpy is a property and state function that resembles energy; it has the same dimensions as energy and derives its value solely from the system's composition, temperature, and pressure, not from its past.

Enthalpy, denoted by the symbol H, is a combination of all the internal energy, denoted by E, plus the product with the pressure and volume, denoted by PV. The shift in internal energy corresponds to the heat transmitted to, lower the work performed by, the system, in accordance with the principle of energy conservation.

Explanation:

Answer:

Q = 7.0

Q = kc. The reaction is in equilibrium

Explanation:

Based on the reaction:

Br₂ + Cl₂ ⇄ 2BrCl

Equilibrium constant of the reaction, kc, is the ratio of equilibrium concentrations products over reactants powered to its reaction coefficient:

Kc = [BrCl]² / [Br₂] [Cl₂] = 7.0

Now, reaction quotient, Q, is write as the same Kc but the concentrations are actual concentrations:

Q = [BrCl]² / [Br₂] [Cl₂]

Replacing:

Q = [0.00415M]² / [0.00366M] [0.000672M]

Q = 7.0

Now, as Q = Kc = 7.0, the reaction mixture is in equilibrium
