What is the formula for pH?

Answers

Answer:

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

Example: Find the pH of a 0.0025 M HCl solution.

The pressure in a Red Rider BB gun cartridge is 1.5 atm. If the rifle was at 25 °C prior to firing, what is the temperature change of the cartridge after firing if the cartridge reaches standard air pressure of 1.0 atm?

Answers

Answer:

–99 °C

Explanation:

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

Initial pressure (P₁) = 1.5 atm

Initial temperature (T₁) = 25 °C

Final pressure (P₂) = 1 atm

Change in temperature (ΔT) =?

Next, we shall determine the final temperature. This can be obtained as follow:

Initial pressure (P₁) = 1.5 atm

Initial temperature (T₁) = 25 °C + 273 = 298 K

Final pressure (P₂) = 1 atm

Final temperature (T₂) =?

P₁/T₁ = P₂/T₂

1.5 / 298 = 1 / T₂

Cross multiply

1.5 × T₂ = 298

Divide both side by 1.5

T₂ = 298 / 1.5

T₂ = 199 K

Converting 199 K to °C, we have:

T(°C) = T(K) – 273

T₂ = 199 – 173

T₂ = –74 °C

Finally, we shall determine change in temperature. This can be obtained:

Initial temperature (T₁) = 25 °C

Final temperature (T₂) = –74 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = –74 – 25

ΔT = –99 °C

Thus, the change in the temperature is –99 °C

Explanation:

Halogens tend to form anions because A) losing electrons will fill their octet faster than gaining them. B) gaining electrons will fill their octet faster than losing them. C) halogen element ionization energies are lower than transition metal ionization energies. D) halogen atomic radii tend to be larger than their corresponding ionic radii. E) halogen atomic radii tend to be smaller than their corresponding ionic radii.

Answers

Answer:

The correct answer is - B) gaining electrons will fill their octet faster than losing them.

Explanation:

Halogens are located in the 17 th group in the periodic table and have elements like fluorine, chlorine bromine and others. All these elements are nonmetals and have similar electron numbers in their octet.

That is the reason of their high effective nuclear charge as they are electronegative and therefore readily get electrons to become anion with other elemnts in chemical reaction. These elements make anion formed when a nonmetal atom gains one or more electrons.

How many atoms are there in 8.80 moles magnesium chloride? (write your answer in scientific notation).

Answers

Answer:

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.

Explanation:

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 1 mole of magnesium chloride contains 6.023*10²³ atoms, 8.80 moles of magnesium chloride contain how many moles of atoms?

[tex]amount of atoms=\frac{8.80 moles* 6.023*10^{23} atoms }{1 mole}[/tex]

amount of atoms= 5.30*10²⁴

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.

What is the molarity of a solution prepared by dissolving 198 g of BaBr2 in 2.00 liters of solution?

Answers

Answer:

The molarity of the solution is 0.335 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic, or atomic species.

Molarity is the number of moles of solute that are dissolved in a certain volume and is calculated by:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

Being the molar mass of BaBr2 equal to 297.14 g/mole, that is to say that 1 mole contains 297.14 grams, the mass of 198 grams are contained in:

[tex]198 grams*\frac{1 mole}{297.14 grams} = 0.67 moles[/tex]

So:

number of moles of solute= 0.67 molesvolume= 2 L

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.67 moles}{2 L}[/tex]

Solving:  

Molarity= 0.335 [tex]\frac{moles}{liter}[/tex]

The molarity of the solution is 0.335 [tex]\frac{moles}{liter}[/tex]

Answer:

2KNO3 + Na --> 2KO2 + NaO2 + N2

Explanation:

on the left side there is 1 Nitrogen molecule, but on the right side there are 2.

So, by adding a coefficient of 2 on the left side the N balances out.

Then, the K's aren't balanced anymore. There are 2 K on the left and 1 K on the right.

So, if a coefficient of 2 is added to KO2 on the left, the K is then balanced.

Now check all the other molecules, and everything else is balanced!

On both sides there are 2 K's, 2 N's, 6 O's, 1 Na.

For the reaction So3 + H2O -> H2SO4, how many grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid

Answers

Answer:

320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.

Explanation:

The balanced reaction is:

SO₃ + H₂O → H₂SO₄

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:

SO₃: 1 moleH₂O: 1 moleH₂SO₄: 1 mole

Being the molar mass of each compound:

SO₃: 80 g/moleH₂O: 18 g/moleH₂SO₄: 98 g/mole

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

SO₃: 1 mole* 80 g/mole= 80 gramsH₂O: 1 mole* 18 g/mole= 18 gramsH₂SO₄: 1 mole* 98 g/mole= 98 grams

Then you can apply the following rule of three: if 1 mole of sulfuric acid is produced by the reaction of 80 grams of sulfur trioxide, 4 moles of sulfuric acid is produced from how much mass of sulfur trioxide?

[tex]mass of sulfur trioxide= \frac{4 moles of sulfuric acid* 80 grams of sulfur trioxide}{1 mole of sulfuric acid }[/tex]

mass of sulfur trioxide= 320 grams

320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.

The mass of the required compound is 320 grams

Chemical reactions

Given the chemical equation expressed as:

[tex]SO_3 + H_2O \rightarrow H_2SO_4[/tex]

According to stochiometry, 1 mole of SO3  produces 1 mole of H2SO4, hence the moles of SO3 will also be 4.00moles

Determine the mass of SO3

Mass = mole * molar mass

Mass = 4.0 * [32+3(16)]

Mass = 4.0 * 80

Mass = 320 grams

The mass of the required compound is 320 grams

Answers

Answer:

2.70 M.  

Explanation:

Molar mass of MgO = 24.3 + 16 = 40.3.

A molar solution will contain 40.3g in 1 Litre.

So 800 mL of 1 molar solution will contain 0.8* 40.3 g MgO.

So the molarity of the given solution

= 87 / (0.8*40.3)

= 2.699 M.

Calculate the pOH and the pH of a 5.0 x 10-2 M solution of NaOH.

Answers

Answer:

pOH = 1.3, pH = 12.7

Explanation:

Since NaOH is a strong base, it will completely ionize; further, since it completely ionizes, our hydroxide concentration (a product of the ionization) will be the same as the given concentration of NaOH.

NaOH -> Na⁺ + OH⁻, [OH⁻] = 5.0 x 10^-2 M

pOH is the negative log of the hydroxide concentration, so plug our hydroxide concentration in:

pOH = -log[OH⁻] = -log[5.0 x 10^-2 M] = 1.3

Since pH + pOH = 14, we can plug in pOH and solve for pH:

pH + 1.3 = 14

pH = 14 - 1.3 = 12.7

Thus, our pOH = 1.3 and pH = 12.7.
