Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.

Molecular formula is defined as an expression that defines a number of atoms of each element in one molecule of a compound.

It can also be defined as a chemical formula that gives the total number of atoms of each elements in each molecules of a substance.

Ozone is defined as a highly reactive gas composed of three oxygen atoms and form a layer above the earth surface called as ozone layer.

1 oxygen atom = 8 g

1 mole of ozone = 8 x 3 = 24 g

7.92 x 10²⁴ = 8110.08 g

24 g = 1 mole

So, 8110.08 g = 337.92 moles

Thus, Ozone has a molecular formula of O3. If 7.92*1024 atoms of oxygen react to form ozone, then 337.92 moles of ozone will produce.

The mass of NH₃ : = 17.629 g

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Given

125 g NCl₃

Required

The mass of NH₃

Solution

mol NCl₃(molar mass : : 120.5 g/mol)

= 125 g : 120.5 g/mol

= 1.037

From the equation, mol ratio NCl₃ : NH₃ = 1 : 1, so mol NH₃ = 1.037

Mass NH₃(molar mass : 17 g/mol) :

= 1.037 x 17

= 17.629 g

The ideal gas equation can be used to obtain the pressure, number of moles, volume and temperature of a gas.

The ideal gas equation gives the relationship between pressure, number of moles, volume and temperature.

To obtain the number of moles of PH3

PV = nRT

n = PV/RT

n = 0.80 atm * 1.50 L/0.082 atmL/Kmol * 298 K

n = 0.049 moles

Number of moles of O2

PV = nRT

n = PV/RT

n = 0.100 atm *  2.28L /0.082 atmL/Kmol * 293 K

n = 0.0095 moles

Fom the reaction equation;

4 moles of PH3 reacts with 8 moles of O2

0.049 moles of PH3 reacts with  0.049 moles * 8/4 moles

= 0.098

Hence O2 is the limiting reacatant.

Mass of P4O10 produced =

8 moles of O2 yields 1 mole of P4O10

0.0095 moles  of O2 yields 0.0095 moles  * 1 mole/8 moles

= 0.0012 moles

Mass of P4O10  = 0.0012 moles * 284 = 0.34 g

Mass of water;

8 moles of O2 yields 6mole of water

0.0095 moles  of O2 yields 0.0095 moles * 6 moles/8 moles

=0.0071 moles

Mass of water = 0.0071 moles * 18 g/mol = 0.13 g

Since 4 moles of PH3 reacts with 8 moles of O2

x moles of PH3 reacts with 0.0095 moles  of O2

x = 0.0048 moles

Moles of PH3 left over = 0.049 moles - 0.0048 moles = 0.0442 moles

Mass of PH3 left over = 0.0442 moles * 34 g/mol

= 1.5 g

No mass of O2 is left over because the limiting reactant is used up.

Total moles of gas left after the reaction = 0.0442 moles +  0.0071 moles = 0.0513 moles

P = nRT/V

P = 0.0513 moles * 0.082 atmL/Kmol * 295.5/3.88L

P= 0.32 atm'

Answer:

12.6 g O2 or

12.60 g O2 (if needed two decimal places)

Explanation:

First convert grams into moles:

17.4 g KCl × 1

74.55

= 0.233 moles of KCl

Next solve for the mole of O2:

= 0.233 × 3 moles of O2

2 moles of KCl

= 0.3495 or

= 0.350 moles of O2

Finally convert the mole to grams:

= 0.350 moles of O2 × 36g

1 mole

= 12.6 g O2 or 12.60 g O2

The use of pomace for animal feed might be chosen if minimizing production costs is desired

Explanation:

i've taken the test

The use of pomace for animal feed might be chosen if minimizing production costs is desired. Therefore, the correct option is option D.

The solid byproduct of pressing grapes, olives, or even other fruits for juice or oil is known as pomace or marc. It includes the fruit's skins, pulp, seeds, or stems. Pomace brandy has traditionally been made from grape pomace. Currently, it is primarily used as fertilizer, animal feed, or to extract bioactive substances like polyphenols.

The Latin word "pomum" is where "pommace" comes from. The phrase "pomace" was first used by the English to describe the byproduct of making cider. Pomace wine, which had an alcohol concentration of three to four percent, was very common during the Middle Ages. The use of pomace for animal feed might be chosen if minimizing production costs is desired.

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

Explanation:

Answer:

F= m x a

force = mass x acceleration

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

Explanation:

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

In this problem, the force that does the work is the one that opposes the weight.

Solid Snake is 75 kg and is carrying 18 kg of equipment. The total mass is:

m = 75 kg + 18 kg = 93 kg

We can calculate the weight using Newton's second law of motion.

F = m . g = 93 kg . 9.8 m/s² = 911.4 N

Solid Snake climbs 27 flights of stairs, each 5.5 m in height.

27 . 5.5 m = 148.5 m

We will use the definition of work.

w = F . s = (911.4 N) . (148.5 m) . (1 kJ/1000 J) = 135.34 kJ

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

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.
