Explanation:

Answer: The pOH value is 2.

Explanation:

Given: \([H^{+}] = 9.9 \times 10^{-13} M\)

pH is defined as the negative logarithm of hydrogen ion concentration.

Hence, pH of the given solution is calculated as follows.

\(pH = -log [H^{+}]\\= - log (9.9 \times 10^{-13})\\= 12\)

The relation between pH and pOH is as follows.

pH + pOH = 14

Therefore, pOH is calculated as follows.

pH + pOH = 14

12 + pOH = 14

pOH = 14 - 12

= 2

Thus, we can conclude that the pOH value is 2.

Answer:

The weak electrolyte is Aqueous acetic acid.

Answer:

The preceding temperature is equivalent to approximately 9.6 K => -263.5 °C

Explanation:

Given the provided problem, the formula may be substituted by the corresponding values:

Pressure (P)= 932 mmHg ==> 1.2 atm

Volume (V) = 2,300 mL ==> 2.31 L

Moles (n) = 3.51 moles ==> 3.51 mol

Proportional constant of ideal gas constant: (R) = 0.08206

Therefore, we can equate the following:

T= (PV)

     nR

T= (1.2 atm · 2.31 L)

   (3.51 mol · 0.08206)

T= 9.6 K ==> -263.5 °C

Thus, the cumulative temperature given the substituents/substance is equivalent to -263.5 °C.

We can make use of the fact that the total pressure of the mixture is the same as the sum of the partial pressure of all the gases in the container. As a result, 400 kPa is the third gas' partial pressure.

The overall pressure exerted by a mixture of gases is equal to the sum of the partial pressures of each of the constituent gases, according to Dalton's law of partial pressures. The partial pressure is the pressure that each gas would have if it occupied the same volume of the mixture at the same temperature on its own.

Mathematically, this can be stated as:

P_total = P_1 + P_2 + P_3

When we plug these figures into the formula, we get:

800 kPa = 100 kPa + 300 kPa + P_3

When we simplify this equation, we obtain:

800 kPa = 400 kPa + P_3

By taking away 400 kPa from both sides, we arrive at:

P_3 = 400 kPa

The kidneys are important to our survival because they play a critical role in maintaining the balance of fluids and electrolytes in the body, as well as removing waste and toxins from the blood. Options 1 and 2 are correct.

The kidneys filter waste from the blood, such as excess water, salts, urea, and other waste products. They remove urine from the body, which helps to maintain the proper balance of fluids and electrolytes in the body. The kidneys do not increase the sugar level in the blood, but they do play a role in regulating blood sugar levels by producing hormones such as renin and erythropoietin.

The kidneys do not make new blood for the body, but they do produce a hormone called erythropoietin that stimulates the production of red blood cells in the bone marrow.

Answer:

Ionic bond and covalent bond

Explanation:

The two main types of chemical bonding are ionic bond and covalent bond.

In an ionic bond, there is a transfer of electrons from one atom to another. Usually from a metal to a nonmetal leading to the existence of an ion pair. Ionic compounds are soluble in water and have high melting and boiling points due to the strong electrostatic interaction between ions in the compound.

A covalent bond involves sharing of electrons between atoms. In an ordinary covalent bond, the shared electrons are furnished by the two bonding atoms while in a dative covalent bond, the two bonding electrons are furnished by only one of the bonding species.

The Percent Yield for the following balanced chemical reaction 75.76%.

Percent yield in chemistry is the percentage of the product's weight to its theoretical yield. In order to quantify the outcome in percent, we divide the experimental yield by the theoretical yield and multiply the result by 100.

Because many chemical reactions produce byproducts, not all of the reactants in the equation actually undergo reaction, percent yield is significant. A poor percent yield in product manufacturing would mean that the corporation is wasting resources, including money and reactants.

Answer:

Equation of Reaction = AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)

Steps:

1. Find the moles of AgNO3 with formula n= Mass/Mr (molecular mass)

so you will get moles= 10.0/ 169.87 = 0.05886854654

2. Using stoichiometry you know the equation has 1 mole so the moles of AgCl are gonna be the same; therefore, you will use again the same formula.

3.  moles= mass/molecular mass

0.05886854654 = x/ 143.32

You rearrange the formula to find the mass

so mass = moles x molecular mass

mass = 0.05886854654 x 143.32

mass= 8.44 grams

The solubility, polarity, melting point, and molecular mass of an organic sunscreen play a crucial role in determining how good the sunscreen is.

Solubility:Solubility determines how well the sunscreen will dissolve in a liquid, particularly water. Water is a universal solvent that may wash away sunscreen, particularly if it is not water-resistant. Thus, the greater the solubility, the less effective the sunscreen will be.

Polarity:UV radiation from the sun might induce photochemical reactions in organic sunscreens, causing them to degrade and become less effective. The polarity of a sunscreen, on the other hand, may prevent this from occurring. This is because the polarity of a sunscreen can impact its capacity to absorb UV radiation. A higher polarity sunscreen will absorb more radiation, lowering the chances of the sunscreen deteriorating.

Melting point:The melting point of a sunscreen is a measure of its ability to resist thermal decomposition. The sun can heat up the skin and the sunscreen, so a sunscreen with a higher melting point is more likely to survive and maintain its effectiveness.

Molecular mass:The molecular mass of a sunscreen determines its thickness. A sunscreen with a lower molecular mass is lighter and more prone to washing off. A sunscreen with a higher molecular mass is denser and will cling to the skin, making it more effective.To summarize, the solubility, polarity, melting point, and molecular mass of an organic sunscreen all play important roles in determining how good the sunscreen is.
