Answer: The final temperature is 248.7 K

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=951.72kPa\\T_1=653.34K\\P_2=362.29kPa\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{951.72}{653.34}=\frac{362.29}{T_2}\\\\T_2=248.7K[/tex]

Thus the final temperature is 248.7 K

Answer:

D. individual electron

Explanation:

Every individual electron  will have its own unique set of quantum numbers.

Quantum numbers are the numbers which describe the values of conserved quantities with respect to the dynamics of a quantum system.They correspond to the Eigen values of operators which commute with the Hamiltonian quantities.

The Hamiltonian quantities can be known with precision simultaneously with the system's energy.Quantum numbers can take values of discrete sets of integers or even half-integers even though they can approach infinity in some cases.

They can specifically describe energy levels of electrons, and can also explain angular momentum,spin,etc.These are used to describe the path of an electron in an atom ,when the quantum numbers of all atoms are combined they must comply with the Schrodinger equation.

The final empirical formula is [tex]C_2 N_5 H[/tex]

Explanation:

Given

The amount of carbon, nitrogen and hydrogen in a given compound is as follows

C:N:H

[tex]2.61 : 6.09 : 1.31[/tex]

On simplifying the ration values  we get

[tex]\frac{2.61}{1.31} : \frac{6.09}{1.31} : \frac{1.31}{1.31}[/tex]

So the final ratio is

[tex]2 : 5 : 1[/tex]

The final empirical formula is [tex]C_2 N_5 H[/tex]

Answer:

[tex]\boxed {\boxed {\sf 4.20 *10^{24} \ atoms \ Al }}[/tex]

Explanation:

To convert from moles to atoms, we must us Avogadro's number: 6.022*10²³. This tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance. In this case, it is atoms of aluminum.

We can use the number as a fraction.

[tex]\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]

Multiply by the given number of moles: 6.98

[tex]6.98 \ mol \ Al *\frac{6.022*10^{23} atoms \ Al}{1 \ mol \ Al}[/tex]

The moles of aluminum will cancel.

[tex]6.98 *\frac{6.022*10^{23} atoms \ Al}{1 }[/tex]

The denominator of 1 can be ignored.

[tex]6.98 * {6.022*10^{23} atoms \ Al}[/tex]

Multiply.

[tex]4.203356*10^{24} \ atoms \ Al[/tex]

The original measurement of moles has 3 significant figures, so our answer must have the same.

For the number we calculated, that is the hundredth place. The 3 in the thousandth place tells us to leave the 0.

[tex]4.20 *10^{24} \ atoms \ Al[/tex]

There are about 4.20*10²⁴ atoms of aluminum in 6.98 moles.

Answer:

C. 12.8 liters.

Explanation:

The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains [tex]6.022 \times 10^{23}[/tex] molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

[tex]P\cdot V = \frac{r\cdot R_{u}\cdot T}{N_{A}}[/tex] (1b)

Where:

[tex]P[/tex] - Pressure, measured in pascals.

[tex]V[/tex] - Volume, measured in liters.

[tex]r[/tex] - Amount of molecules, no unit.

[tex]N_{A}[/tex] - Avogadro's number, no unit.

[tex]R_{u}[/tex] - Ideal gas constant, measured in pascal-liters per mole-Kelvin.

[tex]T[/tex] - Temperature, measured in Kelvin.

If we know that [tex]P = 100000\,Pa[/tex], [tex]r = 3.44\times 10^{23}[/tex], [tex]N_{A} = 6.022\times 10^{23}[/tex], [tex]T = 273.15\,K[/tex] and [tex]R_{u} = 8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K}[/tex], then the volume of carbon dioxide at STP is:

[tex]V = \frac{r\cdot R_{u}\cdot T}{N_{A}\cdot P}[/tex]

[tex]V = \frac{(3.44\times 10^{23})\cdot \left(8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K} \right)\cdot (273.15\,K)}{(6.022\times 10^{23})\cdot (100000\,Pa)}[/tex]

[tex]V = 12.972\,L[/tex]

Therefore, the correct answer is C.

Answer:

the deep ocean

Explanation:

goog   le

The layer which is closest to the surface is least dense.

The ocean can be divided into three main layers:

The surface layer (also known as the epipelagic zone), which extends from the surface to about 200 meters deep and is the warmest and lightest layer.

The mesopelagic zone (or twilight zone), which extends from 200 to 1000 meters deep and is characterized by limited light and declining temperatures.

The bathypelagic zone (or midnight zone), which extends from 1000 to 4000 meters deep and is the coldest, darkest, and most pressure-filled layer.

Below the bathypelagic zone lies the abyssopelagic zone, which extends from 4000 to the ocean floor and is characterized by near-constant darkness and extremely cold temperatures.

Answer:

17.05 g of glucose

Explanation:

The equation of the reaction is given as;

6CO2 + 6H2O → C6H12O6 + 602

From the equation;

6 mol of CO2 produces 1 mol of  C6H12O6

Converting to masses;

CO2:

Mass =Number of moles * Molar mass

Mass = 6 mol * 44 g/mol = 264 g

C6H12O6:

Mass =  Number of moles * Molar mass

Mass = 1 mol * 180 g/mol = 180 g

This means 264g of CO2 produces 180g of C6H12O6

25g of CO2 would produce x g of C6H12O6

264 = 180

25 = x

x = 25 * 180 / 264

x = 17.05 g

Answer:

Explanation:

A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
