Answer:

C. air pollution absorbs carbon dioxide

Explanation:

Carbon dioxide's role in the greenhouse effect is a major contributor to air pollution. Radiation and heat emanating from the earth's surface need to be released out into the atmosphere. But because carbon dioxide levels are so high, there is an ozone effect on the ground level.

Answer: The products formed in this Bronsted-Lowry reaction are [tex]HNO_{2}[/tex] and [tex]PO^{2-}_{4}[/tex].

Explanation:

According to Bronsted-Lowry, acids are the species which donate hydrogen ions to another specie in a chemical reaction.

Bases are the species which accept a hydrogen ion upon chemical reaction.

For example, [tex]HPO^{2-}_{4} + NO^{-}_{2} \rightleftharpoons HNO_{2} + PO^{2-}_{4}[/tex]

Here, the products formed in this Bronsted-Lowry reaction are [tex]HNO_{2}[/tex] and [tex]PO^{2-}_{4}[/tex].

Thus, we can conclude that the products formed in this Bronsted-Lowry reaction are [tex]HNO_{2}[/tex] and [tex]PO^{2-}_{4}[/tex].

Answer:

0.011 moles

Explanation:

Applying,

PV = nRT.................... Equation 1

Where P = Pressure, V = Volume, n = number of moles, R = Molar gas constant, T = Temperature.

Make n the subject of the equation

n = PV/RT.................. Equation 2

From the question,

Given: P = 105 kPa = (105×0.00986923) = 1.036 atm, V = 250 mL = 0.25 L, T = 23 °C = (273+23) = 296 °C

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (1.036×0.25)/(0.082×296)

n = 0.011 moles

Answer: A volume of 2997 liters of fluorine gas is needed to form 999 L of sulfur hexafluoride gas if the given reaction takes place at 2.00 atm and 273.15 K.

Explanation:

The given reaction is as follows.

[tex]S(s) + 3F_{2}(g) \rightarrow SF_{6}(g)[/tex]

This show that 3 moles of fluorine is reacting to give 1 moles of sulfur hexafluoride.

According to the ideal gas formula,

PV = nRT

This means that volume of a gas is directly proportional to the number of moles. Hence, volume of fluorine required is calculated as follows.

[tex]3 \times 999 L\\= 2997 L[/tex]

Thus, we can conclude that a volume of 2997 liters of fluorine gas is needed to form 999 L of sulfur hexafluoride gas if the given reaction takes place at 2.00 atm and 273.15 K.

answer is what is the pH number is that Our New account last name is Our brothers name he will be happy to

The pOH of the solution is 10.4

The pH of the solution is 3.6

From the question, we are to determine the pOH and pH of the solution

pOH can be calculated by using the formula

pOH = -log[OH⁻]

From the question,

[OH⁻] = 4×10⁻¹¹ M

∴ pOH = -log(4×10⁻¹¹)

pOH = 10.4

Hence, the pOH of the solution is 10.4

Now, for the pH

Using the formula,

pH + pOH = 14

Then, we can write that

pH = 14 - pOH

∴ pH of the solution is

pH = 14 - 10.4

pH = 3.6

Hence, the pH of the solution is 3.6

Explanation:

The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons

Uranium has an atomic number of 92. There are 146 neutrons, 92 protons, and 92 electrons in 238U+5. The number of neutrons can vary from 141 to 146.

Chemical element uranium has the atomic number 92 and the letter U. It is an actinide metal in the periodic table's silvery-gray series. There are 92 protons and 92 electrons in an atom of uranium, of which 6 are valence electrons.

Since uranium has an atomic number of 92, its atomic structure consists of 92 protons and 92 electrons. The nucleus of U-238 contains 146 neutrons, but this number can range from 141 to 146.

With 92 protons and 146 neutrons, Uranium-238 is the heaviest element in nature. The overall mass and charge of the nucleus are 238 nucleons, or +92.

Thus, Uranium has an atomic number of 92. There are 146 neutrons, 92 protons, and 92 electrons in 238U+5.
