A sample of Ar gas occupies a volume of 1.2 L at 125 degrees * C and a pressure of 10 atm. Determine the temperature , in degrees Celsius, at which the volume of the gas would be 1.0 L at the same pressure .

[tex]\huge \bf༆ Answer ༄[/tex]

The Correct choice is ~ A

Isotopes are the elements with same Atomic Number but different masses ~

The new temperature of the gas is 115 °C

From the question given above, the following data were obtained:

The new temperature of gas can be obtained as follow:

[tex] \frac{P_1}{T_1} = \frac{P_2}{T_2} \\ \\ \frac{0.96}{298} = \frac{1.25}{T_2} \\ \\ cross \: multiply \\ \\ T_2 \times 0.96 = 298 \times 1.25 \\ \\ divide \: both \: side \: by \: 0.96 \\ \\T_2 = \frac{298 \times 1.25 }{0.96} \\ \\ T_2 = 388 \: K \\ \\ subtract \: 273 \: from \: 388 \: to \: express \: the \: answer \: im \: \degree \: C \\ \\ T_2 = 388 - 273 \\ \\ T_2 = 115 \: \degree \: C [/tex]

Therefore, the new temperature is 115 °C

Explanation:

The volume of carbon dioxide produced when 375 mL of a 75.0% ethanol solution by mass with a density of 1.22 g/mL reacts with excess oxygen is  667.52 L.

We are told in the question that the solution contains 75.0% ethanol solution by mass.

Hence;

Density of solution = mass/volume

mass = Density × volume = 1.22 g/mL × 375 mL = 457.5 g

Mass% = mass of solute/ mass of solution × 100

Mass of solute = x

Mass of solution = 457.5 g

Mass percent = 75.0%

Substituting values;

75 = x/457.5 + x × 100

75/100 = x/457.5 + x

0.75(457.5 + x) = x

343.125 + 0.75x = x

343.125  = x -  0.75x

x = 343.125/0.25

x = 1372.5 g

The equation of the reaction is;

C2H6O(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

Number of moles of ethanol =  1372.5 g/46 g/mol = 29.8 moles

From the reaction equation;

2 moles of ethanol produces 2 moles of carbon dioxide

29.8 moles of ethanol also produces 29.8 moles of carbon dioxide

If 1 mole of carbon dioxide occupies 22.4 L

29.8 moles of carbon dioxide occupies 29.8 moles × 22.4 L/ 1 mole

= 667.52 L

Food waste, like a feather or a bone etc fall into food causing Physical  contamination because the contaminants such as feather and bone are mixed in the food physically not chemically. These contaminants can be removed through physical means such as with the help of hand.

Some contaminants mix with the food chemically means they react with the food and produce something new. Such type of contaminants are present in liquid form so we can conclude that feather or a bone etc when fall into food causing Physical  contamination.

Silicon dioxide is a covalent network solid. Magnesium oxide is an ionic compound while carbon dioxide is a covalent molecule.

Carbon dioxide is a covalent compound. The compound contains polar C-O bonds but overall the compound is nonpolar as such the molecules are held together by only weak dispersion forces.

The compound magnesium oxide is an ionic solid. It is composed of magnesium ions and oxygen ions in a crystal lattice. Owing to the fact that the ions are very small, the lattice energy is large and the compound is almost insoluble in water.

Silicon dioxide is a covalent network solid which is composed of chains of silicon - oxygen bonds. The network solid forms a very rigid structure having a high melting point.

Considering the reaction stoichiometry, the correct answer is second option: the total number of moles of water produced from 13. 35 mol of oxygen is 26.7 moles.

The balanced reaction is:

2 H₂ + O₂ → 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 1 moles of O₂ produce 2 moles of H₂O, 13.35 moles of O₂ will produce how many moles of H₂O?

[tex]amount of moles of H_{2} O=\frac{13.35 moles of O_{2} x2 moles of H_{2} O}{1 mole of O_{2}}[/tex]

amount of moles of H₂O= 26.7 moles

Finally, the correct answer is second option: the total number of moles of water produced from 13. 35 mol of oxygen is 26.7 moles.

Answer: as the wavelength gets shorter, the energy increases; as the wavelength gets longer, the energy decreases. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.

Answer:

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
