Explanation:

A rainbow is produced through a proces that includes refraction, reflection, and dispersion of  sunlight.

A rainbow is formed when sulinght is refracted and reflected by rain drops in the atmospher.

The sunlight is split into its component colors, which is why rainbows appear as having an array of colors. This is due to each color being bent by a different amount during refraction.

The colors of a rainbow are always in the same order, with red on the outside and violet on the inside.

First, we need to write the balanced chemical equation for the reaction:

2 NO2(g) + H2O(l) → HNO3(aq) + NO(g)

From the equation, we can see that 2 moles of NO2 react with 1 mole of H2O to produce 1 mole of HNO3 and 1 mole of NO. Therefore, we need to determine which reactant is limiting and calculate the amount of HNO3 that can be produced based on that.

To do this, we can use the mole ratio of NO2 to H2O:

5.0 mol NO2 × (1 mol H2O / 2 mol NO2) = 2.5 mol H2O

Since we have 11.0 mol of H2O, it is not limiting and we will use up all of the NO2.

Therefore, we can calculate the amount of HNO3 that can be produced from 5.0 mol of NO2:

5.0 mol NO2 × (1 mol HNO3 / 2 mol NO2) = 2.5 mol HNO3

Therefore, the largest amount of HNO3 that could be produced is 2.5 mol, rounded to the nearest 0.1 mol.

Explanation:

Answer:

A carboxylic acid group (-COOH) can form more hydrogen bonds with water than an ester group (-COO-).

Explanation:

The carboxylic acid group (-COOH) is found in the carboxylic acids. This group is ultimately responsible for the solubility of carboxylic acids in water. It is worthy of note that the high boiling points of low molecular weight carboxylic acids is often because they are capable of intermolecular hydrogen bonding which leads to the dimerization of carboxylic acid.

The solubility of carboxylic acids decreases as the length of the alkyl chain increases. Hence, a long chain carboxylic acid is less soluble in water than shorter chain carboxylic acids.

Ester molecules can't form hydrogen bonds with each other but they do form weak hydrogen bonds with water. This leads to the solubility of low molecular weight esters. However, if a carboxylic acid and an ester posses the same length of alky chain, the carboxylic acid will form more hydrogen bonds and thus be more soluble in water than than a corresponding ester of the same chain length.

The effect on the acceleration of the 15-kg box would be that it would experience a greater acceleration than the 30-kg box.

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Therefore, for a given force, an object with a smaller mass will experience a greater acceleration than an object with a larger mass.

In this scenario, if the student applies the same force to both the 30-kg box and the 15-kg box, the 15-kg box will experience a greater acceleration than the 30-kg box. This is because the smaller mass of the 15-kg box means that it has less inertia and requires less force to accelerate.

Therefore, the effect on the acceleration of the 15-kg box would be that it would experience a greater acceleration than the 30-kg box.

To determine the tomato's velocity when it hits the ground, we need more information. Specifically, we need the height from which the tomato was dropped and the tomato mass.

Without these details, it is impossible to calculate velocity accurately. The velocity of an object when it hits the ground depends on factors such as the height of the fall, the mass of the object, and any forces acting on it during the fall (such as air resistance).

If you can provide the necessary information, I can help you calculate the velocity of the tomato when it hits the ground.

Z = 1 - a/VRT

Explanation:

Note :

Compressibility Factor, Z = PV / RT

Vander waal forces at Lower pressure is represented by the expression :

V[P + a/V²] = RT

Aim is to move PV /RT =Z to one side of the equation.

Using change of subject :

opening the bracket :

PV + aV / V² = RT

PV + a/V = RT

Divide through by RT

PV/RT + a/VRT = RT/RT

PV/RT + a/VRT = 1

Recall:

PV /RT = Z

equation becomes :

Z + a/VRT = 1

Subtract a/VRT from both sides

Z + a/VRT - a/VRT = 1 - a/VRT

Z = 1 - a/VRT

The properties of a natural resource that make it useful for humans as a material or energy source is the ability to convert mass into energy and vice versa.

The expression natural resources make reference to all types of matter and energy extracted from nature that can be used to produce goods and services.

Some examples of natural resources include for example irreversible resources such as fossil fuels (i.e., oil, or coal, gas, minerals such as metals, rocks, etc) as well as those based on the use of reversible energy such as eolic air energy, solar radiation or sunlight, soil and hydric resources or water.

Therefore, with this data, we can see that natural resources can be defined as any material and or energy obtained from nature that may be irreversible or reversibly used to produce goods and services.

Stars form in large, dense regions of gas and dust known as molecular clouds. These clouds are located primarily in the spiral arms of galaxies, where they are exposed to intense radiation from nearby stars. As the gas and dust in these clouds are subjected to this radiation, they begin to collapse under their own gravity. As the collapse continues, the cloud becomes denser and denser, and eventually a protostar forms at its center. Over time, this protostar continues to contract and heat up, eventually reaching the point where nuclear fusion can begin in its core. At this point, the protostar becomes a fully-fledged star, and the process of star formation is complete.

TL;DR: Within the clouds of dust and scattered throughout most galaxies.

Answer:

A. Hydrogen cans oxygen are reactants

Explanation:

Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.

Answer:

17.5 L

Explanation:

Step 1: Given data

Step 2: Calculate the final volume of the nitrogen

We have a gas that undergoes a change at a constant temperature. If we assume an ideal behavior, we can calculate the final volume of the nitrogen using  Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 1 atm × 14.0 L/0.8 atm = 17.5 L

The volume of hydrogen gas produced is 19.8 L.

The balanced chemical equation is given as;

Zn + 2HCl → ZnCl₂ + H₂

from the reaction above;

1 mole of Zn = 1 mole of H₂

number of mole of 48.5 g Zn  is calculated as

48.5 g  /65.4 g/mol

= 0.74 mol Zn  = 0.74 mol H₂

The volume of hydrogen gas produced is calculated as follows;

PV = nRT

where;

T = 27°C + 273 = 300 K

V = nRT/P

V = (0.74 x 0.08206 x 300) / (0.921)

V = 19.8 L

Answer:

the material will be water and oxygen

Answer:

18.015

Explanation:

Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen's is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

Answer:

The concentration of hydrogen ions in a solution can be found by measuring the pH of the solution using a pH meter or pH paper, and then using the following equation:

[H+] = 10^(-pH)

where [H+] is the concentration of hydrogen ions in moles per liter (M) and pH is the negative logarithm of the hydrogen ion concentration.

Alternatively, if you know the concentration of a strong acid or base in the solution, you can calculate the concentration of hydrogen ions using the concentration of the acid or base and the dissociation constant (Ka or Kb) for the acid or base. For example, for a strong acid, the concentration of hydrogen ions is equal to the concentration of the acid, while for a strong base, the concentration of hydroxide ions is equal to the concentration of the base.

The eutectic point is the lowest temperature at which the liquid phase is constant at a particular pressure.

A melting composition known as a eutectic consists of at least two components that melt and freeze at the same rates. The components combine during the crystallisation phase, operating as a single component as a result.

The eutectic is the system's lowest melting point under its own pressure; it has a matching temperature called the eutectic temperature and produces the eutectic liquid as a result. In terms of composition, eutectic liquids are located between the system's solid phases.
