Scientists that work in Antarctica mostly refer to the majority of the continent as being a cold desert

Explanation:

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

2H₃PO₄ + 3Ca(OH)₂ —> Ca₃(PO₄)₂ + 6H₂O

From the balanced equation above,

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

The man has been missing for two days. The average temperature the previous 48 hours was 50° fahrenheit. 12-24 hours is the time. body was discovered.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is a part of several measurements that are used to compare the length of events or the gaps between them.

To compare how long they last, to order events, and to measure how quickly things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as an a fourth dimension. A body was discovered in the woods. The man has been missing for two days. The average temperature the previous 48 hours was 50° fahrenheit. 12-24 hours, body was discovered.

Answer:

A structural formula is shown, making the answer D.

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.

Chemical equilibrium is a dynamic equilibrium whereby the forward and backward reactions are occurring at the same rate.

Chemical equilibrium refers to a situation in which the forward reactions and the backward reactions in a reversible reaction are occurring at the same same same rate.

Factors that affect equilibrium include:

For a closed reaction system in equilibrium, the equilibrium position of the reaction will adjust to nullify any changes imposed on the system.

Therefore, chemical equilibrium is a dynamic equilibrium.

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.

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.

Answer:

Its phosphorus (P)

Explanation:

In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.

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.

2KOH --> K²O + H²O

Explanation:

Potassium Hydroxide = KOH

Potassium oxide = K²O

Water = H²O

KOH --> K²O + H²O

K = 1. K = 2.

2KOH --> K²O + H²O

O = 2. O = 2.

H = 2. H = 2.

Balanced symbol = 2KOH --> K²O + H²O

Balanced word = 2Potassium Hydroxide --> Potassium oxide + Water.
