Answers

Answer 1

The statement that is true is that; the student made a solution and then a het---erogeneous mixture.

What is true about the set up?

We know that a solution is composed of a substance that dissolves in a solvent. The solution is made when the red coloring is dissolved in the water and then when we add the oil, there is now a layer that is not in phase with the rest of the solution.

The vegetable oil would then tend to separate out of the rest of the solution and then form a het--erogenous mixture. We can be able to have the two of them come together by stirring the mixture for some time.

What is ocean acidification?

Ocean acidification is the global decrease in seawater pH caused by the oceans' extensive uptake of atmospheric carbon dioxide (CO2) in the atmosphere. Ocean acidification is primarily caused by the Earth's atmosphere being overburdened with massive amounts of CO2, which is created by automobiles, industrial processes, and agricultural activities.

A third to a half of the CO2 produced into the atmosphere by human activity since the start of the Industrial Revolution, or around 1750, is being absorbed by the oceans. Scientists believe that at that time, seawater's average pH decreased between 8.19 to 8.05, representing a 30% increase in acidity.

Chemical reactions happen absolutely everywhere. While we sometimes associate chemical reactions with the sterile environment of test tubes and laboratories, nothing is farther from the truth. In fact, a vast number of transformations are creating a dizzying and almost incomprehensible series of new matter and energy changes in our world every second of every day.

(reactants ) into another group of substances (products) is a so-called chemical reaction.

Moles KO2 = 2.44g/(71.1g/mole) = 0.034 moles

Moles CO2 = 4.45g/(44g/mole) = 0.10 moles

4KO2 + 2CO2 —> 2K2CO3 + 3O2

The reaction requires twice as many moles of KO2 than moles of CO2.  That means 0.10 mole of CO2 would consume 0.20 moles of KO2.  But we only have 0.034 moles of KO2, so the limiting reagent is KO2.  

There are 3 moles of O2 produced for every 2 moles of CO2 consumed.  In this case we'll assume all of the KO2 reacts, so that should result in (3/4) * (0.034moles) = 0.025 moles of O2 .

What kind of light is absorbed by greenhouse gases like CO2 to cause warming of the atmosphere?

Answers

The kind of light absorbed by greenhouse gases that causes the warming of the atmosphere is infrared light.

What is global warming?

Global warming refers to the increase in the average global temperature as a result of an increased amount of absorbed infrared light by greenhouse gases.

Greenhouse gases are gases that form a blanket layer in the atmosphere and prevent reflected low-energy infrared light from the sun from returning back to space. By absorbing this light, greenhouse gases are able to keep the earth warm.

However, as the concentration of greenhouse gases keeps increasing in the atmosphere, so is the amount of infrared light absorbed. Consequently, the atmosphere keeps getting warmer. The more the concentration of the gases increases, the more the temperature.

This is what is currently causing global warming.

What is theoretical yield?

The theoretical yield is the greatest amount of a product that can be produced in a chemical reaction. It can be determined using the chemical equation with balance. the relative formula mass, mass, and mass of the  limiting reactant, as well as the relative formula mass of the result

Given,

Mass of H₂ = 1.96 g

Mass of N₂ = 9.78 g

Molar mass of H₂ = 2 g/mol

Molar mass of N₂ = 28 g/mol

Lets calculate the moles of N₂ and H₂,

Moles of H₂ = [tex]\frac{given mass}{molar mass}[/tex]

H₂ = [tex]\frac{1.96}{2}[/tex]

H₂ = 0.98 mol

same for moles of N₂ = [tex]\frac{given mass}{molar mass}[/tex]

N₂ = [tex]\frac{9.78}{28}[/tex]

N₂ = 0.349 mol

Now, calculate limiting and excess reagent.

The balanced chemical equation is:

3H₂ + N₂ = 2NH₃

From the balanced reaction we conclude that.

As, 3 mole of H₂ react 1 mole of N₂

So, 0.98 moles of H₂ react with 0.98/3 = 0.32 moles of N₂

From this we conclude that, N₂ is an excess reagent because the given moles are greater than the required moles and H₂ is a limiting reagent and it limits the formation of product.

Let us calculate the moles of NH₃

From the reaction, we conclude that

As, 3 mole of H₂ react to give 2 mole of NH₃

So, 0.98 mole of H₂ react to give [tex]\frac{2}{3}[/tex]×0.98 = 0.65 mole of NH₃

Now we have to calculate the mass of NH₃

Mass of NH₃ = Moles of NH₃ × Moles of NH₃

Answers

The theoretical yield of H₂O in this reaction is 31.69 Kg.

The chemical equation of the reaction of NH₃ and O₂ is,

NH₃ + O₂ → NO + H₂O

Now, balancing this equation,

4NH₃ + 5O₂ → 4NO + 6H₂O

So, as per reaction, we can see,

NH₃ is limiting reagent, hence it will decide the extent of products,

4 moles of NH₃ reacts completely with two oxygen to form 6 moles of water.

Moles = Mass reacted/formed/molar mass.

Molar mass of NH₃ = 17.04 g/mol

Reacted mass of NH₃ = 45000 g.

Molar mass of H₂O is 18 g/mol

Now, can write,

4 x (mass of NH₃ reacted/molar mass of NH₃) = 6 x (mass of H₂O formed/molar mass of H₂O)

4 x (45000/17.04) = 6 x (Formed mass of H₂O/18)

Formed mass of H₂O = 31690.14 grams.

Formed mass of H₂O = 31.69 Kg.

hydroxylamine contains 42.41% n and 9.15% h by mass, with the remainder being oxygen. what is its empirical formula?

Answers

The empirical formula of hydroxylamine is Nitrogen 1, Hydrogen 3 and oxygen 1 (N1H3O1).

To find the empirical formula, we must first figure out the amount of oxygen present, which is equal to 100 minus the percentages of nitrogen and hydrogen present. Combining the values gives us the following outcome: The amount of oxygen present is expressed as 100 minus 42.41 and 9.15, which equals 48.44. Nitrogen is 42.41, contains 9.15 percent hydrogen, and has 48.44 percent oxygen. The smallest amount will be shared. When divided by 3.0275 and 3.0229, respectively, the least nitrogen value will equal nearly 1, which is nitrogen. 9.15 divided by 3.0275 = 3, and 3.0275 divided by 3.0275 equals 1 for oxygen and hydrogen. The nitrogen concentration in this instance is 1. 3. 1 points are needed to compare hydrogen to oxygen.

in a mixture of an alcohol and ketone of equal molecular weight, which will have the larger rf value and why?

Answers

The ketone will have a larger rf value because it is more polar than the alcohol.

Does more polarity suggest a greater or lesser Rf value?

Calculating the Rf value is possible if you can see the spots.The identity and properties of the various compounds can be established using the Rf values.Since more polar compounds have a stronger affinity for the polar solid phase, they will have smaller Rf values.Rf values are typically higher for low-polarity chemicals compared to higher-polarity ones. Generally speaking, as the polarity of a compound increases, so does its absorptivity (i.e., the more polar the compound, the stronger it binds to the adsorbent).

Surprisingly, dipole-diple is not the predominant intermolecular force between ibr molecules in liquid ibr. Based on this information, what must be the main imf for ibr?.

Answers

Dipoles are not the dominant intermolecular forces between IBr molecules in liquids. IBr is a covalent bond.

A covalent bond is a chemical bond that requires the sharing of electrons to form electron pairs between atoms. The constant balance between attractive and repulsive forces between atoms according to their share of electrons is called a covalent bond.

Covalent bonds are much more common in natural chemistry than ionic bonds. A covalent bond is the simultaneous attraction of the nucleus to one or more electron pairs. Covalent compounds generally have low boiling and melting factors and are determined in all three body states at room temperature. Covalent bonds no longer conduct electricity; This is because covalent compounds no longer have charged particles that can carry electrons.

Salt in crude oil must be removed before the oil undergoes processing in a refinery. The crude oil is fed to a washing unit where freshwater fed to the unit mixes with the oil and dissolves a portion of the salt contained in the oil. The oil (containing some salt but no water), being less dense than the water, can be removed at the top of the washer. If the spent wash water contains 15% salt and the crude oil contains 5% salt, determine the concentration of salt in the washed oil product if the ratio of crud oil (with salt) to water used is 4:1.
