Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of[tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex] is dtermined using ICE tables.

What are acid dissociatio constants [tex]K_{a}[/tex]?

An acid dissociation constant, [tex]K_{a}[/tex] of an acid is a measure of the strength of the acid in solution. The larger the [tex]K_{a}[/tex] value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large [tex]K_{a}[/tex] values.

It is written as a  qoutient of the equilibrium concentrations of the aqueous species in the acid solution.

[tex]K_{a} = \frac{[H^{+}] [A^-{}]}{HA}[/tex]

For the weak acids such as [tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex], their equilibrim concentrations are determined using their [tex]K_{a}[/tex] values and an ICE table.

The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution

Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.

Therefore, acids have low pH and weak acids have low [tex]K_{a}[/tex] values.

Assume you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution. How would this affect the reaction rate?

Answers

The reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

What happen when the vitamin C is added in lower amount?

If you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution, the reaction rate is affected because of the lower amount of reactant for the chemical reaction. If the reactants are present in larger amount then the products are also produced in large concentration.

So we can conclude that the reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

Calculate the volume in mL of 0.279 M Ca(OH)2 needed to neutralize 24.5 mL of 0.390 M H3PO4 in a titration.



Note: the answer should have 3 significant digits. Do not include the unit mL in the answer.

Answers

The volume of the 0.279 M Ca(OH)₂ solution required to neutralize 24.5 mL of 0.390 M H₃PO₄ is 51.4 mL

Balanced equation

2H₃PO₄ + 3Ca(OH)₂ —> Ca₃(PO₄)₂ + 6H₂O

From the balanced equation above,

The mole ratio of the acid, H₃PO₄ (nA) = 2The mole ratio of the base, Ca(OH)₂ (nB) = 3

How to determine the volume of Ca(OH)₂ Molarity of acid, H₃PO₄ (Ma) = 0.390 MVolume of acid, H₃PO₄ (Va) = 24.5 mLMolarity of base, Ca(OH)₂ (Mb) = 0.279 MVolume of base, Ca(OH)₂ (Vb) =?

MaVa / MbVb = nA / nB

(0.39 × 24.5) / (0.279 × Vb) = 2/3

9.555 / (0.279 × Vb) = 2/3

Cross multiply

2 × 0.279 × Vb = 9.555 × 3

0.558 × Vb = 28.665

Divide both side by 0.558

Vb = 28.665 / 0.558

Vb = 51.4 mL

Thus, the volume of the Ca(OH)₂ solution needed is 51.4 mL

How is fission different than alpha or beta decay?

Answers

Fission is when the parent atom splits into two daughter products. Whereas atom with a mass number is lower by 4 and an atomic number is lower by 2.

Is nuclear fission alpha or beta?

Fission outcomes emit beta radiation, while actinides mainly emit alpha radiation. Many of each also radiate gamma radiation.

The beta decays form an isobaric, fission-product decay chain for each mass number.

Thus, Fission is when the parent atom splits into two daughter products.

If 30 grams of KCl is dissolved at 10°C, how many additional grams would be needed to make the solution saturated at 60°C? * Captionless Image 45g 20g 15g 75g

Answers

If 30 grams of KCl is dissolved at 10°C, 14 g of KCl should be added to make a saturated solution at 60 °C.

What is a saturated solution?

A saturated solution is a solution in which there is so much solute that if there was any more, it would not dissolve. Its concentration is the same as the solubility at that temperature.

Step 1. Calculate the mass of water.

At 10 °C, the solubility is 31.2 g KCl/100 g H₂O.

30 g KCl × 100 g H₂O/31.2 g KCl = 96 g H₂O

Step 2. Calculate the mass of KCl required to prepare a saturated solution at 60 °C.

At 60 °C, the solubility is 45.8 g KCl/100 g H₂O.

96 g H₂O × 45.8 g KCl/100 g H₂O = 44 g KCl

Step 3. Calculate the mass of KCl that must be added.

44 g - 30 g = 14 g

If 30 grams of KCl is dissolved at 10°C, 14 g of KCl should be added to make a saturated solution at 60 °C.

I will give 500 points! What is the composition of Milk?

Answers

Answer:In general, the gross composition of cow's milk in the U.S. is 87.7% water, 4.9% lactose (carbohydrate), 3.4% fat, 3.3% protein, and 0.7% minerals (referred to as ash).

Explanation:

i got it ccorerct

Answer:

The milk of goats and sheep is similar in composition to that of cows.

Milk protein consists mainly of casein, and it exists in several classes: α, β, etc. If milk pH falls below 4.6, the casein precipitates. Although casein represents 80–85% of total milk protein, when precipitation occurs, the liquid portion is referred to as whey.

The remaining proteins are found in whey, and they include serum albumin, immunoglobulins, α-lactalbumin, etc. Milk carbohydrate is lactose, and its content is fairly consistent among breeds of milk cows at around 5.0%.

lactose is the main sugar; smaller quantities of glucose and citric acid exist. The fat content varies between ca. 3.5 and 5.0% depending upon cattle breed.

The ash content of around 0.7% consists of a relatively high level of Ca2+ and a lower level of Fe2+.

The pH of fresh whole milk is around 6.6 but it may reach ca. 6.8 from a cow that has mastitis.

Mastitis is an infection of the udder that is most often caused by Streptococcus agalactiae and S. Uberois but sometimes by Staphylococcus aureus or Streptococcus dysgalactiae.

Fresh milk of mastitis cows mainly has leucocytes (white blood cells) >106/ml as compared to nonmetastatic milk which has 70,000/ml leucocytes.

Milk contains a very adequate supply of B vitamins with pantothenic acid and riboflavin being the two most abundant. Vitamins A and D are added for human consumption, and their presence has no known effect on the activity of microorganisms.

Overall, the chemical composition of whole cow’s milk makes it an ideal growth medium for heterotrophic microorganisms, including the nutritionally fastidious Gram-positive lactic acid bacteria. However, the milk microbiota utilizes these constituents and brings about its spoilage.

Answer:

Explanation:

On the reactant side, XeO3 is a strong oxidizing agent. It can be a solid or gas. Most likely it is in a solid state.

H+ and Br- combine to form HBr which is a weak acid. So H+ and Br- are in an aqueous state.

On the product side, both Br2 and Xe are not very soluble in water. They will be in gaseous state and H2O is water i.e. liquid state.
