Classify the following alcohols as primary secondary and tertiary alcohols​

Answers

Following is the list of primary secondary and tertiary alcohols.

Alcohols are chemical compounds made composed of an alkyl or aryl group and a hydroxyl group (ROH). A fundamental alcohol is a hydroxyl carbon with just one R group. If it contains two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.

Look at the carbon bonded to OH to identify whether an alcohol is primary, secondary, or tertiary. The alcohol is primary, secondary, or tertiary depending on how many other carbons are connected to that carbon. It is methanol if there are three hydrogens and no carbons, which is a rare combination.

A chemical supply company sells sulfuric acid (H2SO4) in a concentration of 4.00 M. What volume of this solution would you need to make 12.0 mL of a 0.50 M H2SO4 solution

Answers

you need 3.00 mL of the 4.00 M sulfuric acid solution to make 12.0 mL of a 0.50 M solution.

What is Solution?

Solution is a way to solve a problem or address an issue. It can involve finding an answer or coming up with a strategy to tackle a difficult situation. Solutions can be found through research, brainstorming, trial and error, or by using existing resources.

To solve this problem, we must use the equation:
V1C1 = V2C2
Where V1 is the volume of the concentrated solution, C1 is the concentration of the concentrated solution, V2 is the volume of the dilute solution, and C2 is the concentration of the dilute solution.
In this case, V1 is the volume of the 4.00 M solution that we need, C1 is 4.00 M, V2 is 12.0 mL, and C2 is 0.50 M.
Plugging these values into the equation, we can solve for V1:
V1 = (V2C2) / C1
V1 = (12.0 mL)(0.50 M) / (4.00 M)
V1 = 3.00 mL

Answers

Option B, Using an excess of aldehyde in the aldol-dehydration reaction is done primarily to ensure complete conversion of the reactants to the desired product.

An excess of aldehyde is used to ensure that there is a sufficient concentration of the aldehyde present in order to form the enolate anion, which is the reactive intermediate in the aldol-dehydration reaction. To achieve high yield: Using an excess of aldehyde allows for the formation of multiple enolate anions, which increases the chances of a double aldol-dehydration reaction taking place, resulting in the formation of the desired product.

The theoretical yield of a reaction is 5.00 moles of potassium permanganate . If the reaction actually produces 616.2 g KMnO₄ ,  the percent yield of the reaction is 78 %.

given that :

the theoretical yield of the reaction = 5 mol

mass of the potassium permanganate = 616.2 g

molar mass of the potassium permanganate = 158 g /mol

moles of the  KMnO₄ = mass / molar mass

                                   = 616.2 / 158

What happens to the energy put into the ice maker? (What is it used to do? How
is it transformed or transferred?)

Answers

Answer:

When ice or any other solid melts, its potential energy increases. Indeed, this is the only increase in energy, since the thermal kinetic energy, or temperature, does not increase while melting. Potential energy is the latent energy that could be released by the water, and this increases because the water will release heat energy if it is frozen solid again.

Ice is the lowest energy state of water at normal Earth pressures. At each phase change of water, whether ice to liquid water or liquid water to water vapor, the potential energy decreases. This is due to the Law of Conservation of Energy. Materials undergoing a change of state absorb or release heat energy, but their temperatures do not change. This is because, while the state change is occurring, all the heat energy is converted into the potential energy of the new state of matter.

Water, in particular, has a very large change in potential energy during phase changes. It takes a great deal of energy to change water from one state to another. This is because of the strong hydrogen bonds that form between water molecules. The liquid phase allows water molecules to be in contact with each other, while the solid phase puts water molecules in an overall optimal configuration relative to each other.

What is Evaporation ?A type of vaporisation called evaporation takes place on the surface of a liquid as it transitions into the gas phase. When humidity impacts the rate of evaporation of water, for example, a high concentration of the evaporating substance in the surrounding gas considerably slows down evaporation.A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day or when wet clothing dries in the sun. In these instances, the liquid water is evaporating into a gas known as water vapour rather than really dissipating. Global evaporation takes place.Evaporation occurs on surfaces. The top layer of the liquid evaporates because the molecules with the highest kinetic energy escape into the air, causing it to become lighter.

Answer:

Hey there! Just wanted to let you know that the term RMA stands for "relative molecular mass" in chemistry. This is a measure of the size of a molecule, calculated by adding up the atomic weights of all the atoms in the molecule. For example, the relative molecular mass of water (H2O) is 18, because the atomic weight of hydrogen (H) is 1 and the atomic weight of oxygen (O) is 16. The relative molecular mass of a molecule is typically expressed in atomic mass units (amu) and can be useful for characterizing and comparing different substances, and predicting their physical and chemical properties.

Fictitious element X has an average atomic mass of 122. 131 u. Element X has two naturally occuring isotopes. The most abundant isotope has an isotopic mass of 121. 552 u and a relative abundance of 61. 35%. Calculate the isotopic mass of the least abundant isotope

Answers

The isotopic mass of the least abundant isotope will be 123.05 u.

Average atomic mass of X = 122.131 u

Assume most abundant isotope = Y and least abundant isotope = Z

Relative abundance (Y) = 61.35%

So,

Z = 100 - 61.35

Z = 38.65 %

Isotopic mass of Y= 121.552 u

Isotopic mass of Z = ?

To calculate the isotopic mass we use the following formula:

Average atomic mass = [(mass Y × percent abundance) + (mass Z × percent abundance)] / 100

put the values

122.131 = [(121.552 × 61.35) + (Z × 38.65)] / 100

12213.1 = (7457.22) + (Z × 38.65)

Z × 38.65 = 12213.1 - 7457.22

Z × 38.65 = 4755.88

Z = 4755.88 / 38.65

These elements have a full valence electron shell, meaning that they have the maximum number of electrons possible in their outermost energy level. This makes them very stable and resistant to chemical reactions, as they do not have any electrons that can be easily removed or added.

As a result, they have very high ionization energy, meaning that a large amount of energy is required to remove an electron and form an ion. Due to these properties, these elements are not readily reactive with other elements and tend to exist as diatomic molecules or as individual atoms.

The gauge pressure equation states that gauge pressure equals the difference between absolute pressure and atmospheric pressure: P G = P P A, or PG=PPA. A tire pressure gauge, for example, monitors the pressure in the tire above ambient pressure. Gauge pressure is the pressure in particular items.

Answers

Answer:

0.0272 moles

Explanation:

The number of moles of acid that were neutralized can be found by multiplying the volume of the base (in liters) by its concentration (in moles/liter) and then multiplying that value by the stoichiometric coefficient of the acid in the balanced chemical equation for the neutralization reaction.

To begin, we need to convert the volume of the base from milliliters to liters.

50.40 mL = 0.0504 L

Next, we can multiply the volume of the base (in liters) by its concentration (in moles/liter) to find the number of moles of base used in the titration.

0.0504 L * 0.542 M = 0.0272 moles

Since this is a neutralization reaction between a monoprotic acid and a strong base, the acid:base ratio is 1:1.

So the acid that has been neutralized is also 0.0272 moles.

The tire pressure of a car increases after driving. This is due to the air inside the tires heating up as a result of friction (a contact force) between the tires and the road.
