Answer 1

Acquisition is the learning process that occurs when a connection between a stimulus and a response is strengthened as learning begins.

What are learning process?

Learning process are described as those processes people pass through to acquire new knowledge and skills and ultimately influence their attitudes, decisions and actions.  

These processes brings about what is called Classical conditioning, which is referred to as learning that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behavior.

After the association is learned, the previously neutral stimulus is now very sufficient to produce the desired behavior.

Answers

The sole difference between a polymer and a monomer is size. A polymer is made up of tiny, repeating units called monomers. When a polymer is condensed by polymerization, a monomer is created.

The term "monomer" refers to a single atom, tiny molecule, or molecular fragment that, when joined with other monomers of the same or closely related types, produces a bigger, macromolecule known as a polymer. Through a process known as polymerization, monomers join together to form polymers through the creation of chemical bonds or supramolecular binding. Polymers are huge molecules that are created by the bonding of monomers, which are the components of a molecule. The major categories of macromolecules are known as polymers, which are macromolecules created by the union of monomers that are present in the cell such as proteins, lipids, carbohydrates, and nucleic acids

Answers

The boiling point of the solution is 100.208°C.

What is boiling point?

The boiling point is defined as elevation in temperature. It is a colligative property means which depends on the concentration of solute.

The temperature at which the pressure of a liquid exerted by its surroundings equals the pressure of the liquid's vapour is known as the boiling point.

At this temperature, the addition of heat causes the liquid to turn into its vapour without raising the temperature.

Molar mass of Al(NO[tex]_3[/tex])₃ = 212.996 g/mol

No. of moles = 14.2/212.996 g/mol

                      = 0.066 mol

Molarity = 0.066/655 × 1000

              = 0.1 M

i = 4 ⇒ ΔT = 0.52° × 0.1 × 4

ΔT = 0.208°

Chemical compounds known as aromatic compounds are those that lack individual alternating double and single bonds in favour of conjugated planar ring systems and delocalized pi-electron clouds.

They are also known as arenes or aromatics. Toluene and benzene make for the greatest examples. Huckel's rule must be followed for aromatics. The only way for creatures to obtain benzene-ring molecules is through plants and microbes. Therefore, plants and microbes create the vast majority of aromatic compounds found in nature, and animals rely either directly or indirectly on plants for the production of numerous aromatic compounds.

A major component of gasoline is octane. When liquid octane is burned in air it reacts with oxygen gas to produce carbon dioxide gas and water vapor. Calculate the moles of oxygen needed to produce of water. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answers

The moles of oxygen needed to produce water is 0.50 mol O2.

When liquid octane is burned in the air, it undergoes a chemical reaction with oxygen gas. Octane is a hydrocarbon, meaning it contains hydrogen and carbon atoms. During the combustion reaction, the hydrogen atoms in the octane react with oxygen molecules (O2) from the air to form water vapor (H2O).

The carbon atoms in the octane react with oxygen molecules (O2) from the air to form carbon dioxide (CO2). This reaction releases energy in the form of heat and light.

The equation for this reaction is as follows:

C8H18(l) + O2(g) → CO2(g) + H2O(g)

For every 1 mole of octane (C8H18) that is burned, 2 moles of oxygen (O2) are needed to produce 1 mole of water (H2O).

Therefore, if we want to calculate the moles of oxygen needed to produce 1 mole of water, we need to divide 1 mole of water by 2 moles of oxygen, which gives us 0.50 moles of oxygen.

The final answer is 0.50 mol O2, which should be rounded to two significant digits.

a sample of gas initially at 0.92 atm and a temperature of 23.2 oc is heated to 40.1 oc. the resulting pressure is 1.3 atm which occupies a volume of 500. ml. what is the initial volume of the sample in milliliters?

Answers

From the gas law, PV=nRT we can say that P(pressure), V(volume) and T (temperature) are related to each other. The initial volume of sample is 408 ml

Given that initial volume of the sample = V1

initial pressure of the sample = 0.92atm

initial temperature of the sample = 23.2oC

Final pressure of the sample = 1.3atm

Final  temperature of the sample = 40.1 oC

Final  volume of the sample = 500ml = 0.5L

Using the relation P1V1/T1 = P2V2/T2

V1 = 1.3x0.5x23.2/40.1x0.92 = 15.08/36.892 = 0.408

Answers

The percent yield of the solution is 17.7% that can be calculated by using experimental and theoretical yield.

Moles of silver nitrate = 305/169.87 = 1.8 moles.

The balanced equation is  2NaOH+H2SO4→Na2SO4+2H2O.

The formula to calculate molarity is

c=n/v

n= c×v

Where, n = moles v= volume and c= molarity

So, the moles in NaOH

nNaOH = 0.125 × 0.75/ 1000

It asks you to find the concentration, which is the safe to assume that the unit is Molarity (M). Also, the  unit was used in  the problem as well.

Molarity has the  units of moles/L so we have to work on getting to this point.

The problem states that you have the  2.29 mL of a 6.00 M concentration. First, we will need moles. To get the  moles, we use stoichiometry,

2.29 mL = 0.00229 L

0.00229 L x ( 6 moles/ L) = 0.01374 moles

0.00229 L x ( 6 moles/ L) = 0.01374 moles

This is how many moles are present inside the solution.

To find the new concentration, we divide the total number of moles by the new volume in the Liters:

0.01374 moles/0.100L = 0.1374 M

Rounding to two significant figures, we get 0.13 M.

What is titration ?

To determine the concentration of an identified analyte, titration is a typical laboratory technique for quantitative chemical analysis. A standard solution with a known concentration and volume is prepared as the reagent, also known as the titrant or titrator.

The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.

Thus, 150ml of 0.50 M NaOH are required to completely titration, 15.0 mL of .20 M HNO₃ solution.
