The process of diffusion can be described as: Movement of water from the area of high concentration of solute to the area of low concentration of solute. Movement of solute from the area of low concentration of solute to the area of high concentration of solute. Movement of water from the area of low concentration of solute to the area of high concentration of solute. Movement of solute from the area of high concentration of solute to the area of low concentration of solute.

Answers

Answer:

Movement of water from the area of high concentration of solute to the area of low concentration of solute.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.

Hence, the process of diffusion can be described as movement of water from the area of high concentration of solute to the area of low concentration of solute.

A solute can be defined as a substance that is typically dissolved in a liquid solvent such as water, coffee, tea, etc., to produce a solution.

Which statement describes a condensation reaction?

A. monomers break away when one forms a double bond monomers break away with the addition of a water molecule.
B. Two monomers combine when one adds to the double bond of another.
C. Two monomers form a new bond with the loss of a water molecule .

Answers

The statement that describes a CONDENSATION reaction is that two monomers form a new bond with the loss of a water molecule . That is option C.

CONDENSATION REACTION involves the combination of two or more molecules(monomers) of water. In  reaction, a new bond is usually formed.

The characteristics of a condensation reaction includes:

formation of complex molecules (combination of two smaller monomers),water is usually given off as by product it requires a catalyst for a complete reaction to occur

A reaction is called a condensation reaction because a small molecule such as water is released as a byproduct.

A typical example of a condensation reaction is the condensation of amino acids to form dipeptide. The  −OH  from the carboxyl group of one amino acid combines with a hydrogen atom from the amine group of the other amino acid to produce water.

Therefore, the statement that describes a CONDENSATION reaction is that two monomers form a new bond with the loss of a water molecule. That is option C

Answers

Answer:

The correct answer is - not very effective; forewarning tends to reduce the effectiveness of an attitude change

Explanation:

The strategy of forewarning or warning before attempting any change in the psychology of an individual is found to be less effective. The subject sees a  forewarning seen as a warning that a person is going to attempt to make changes in the attitude of a person about a particular thing or situation.

As a result, the person is ready to defenses up with regard to that idea of persuasion which Builds up defenses for the situation. Therefore, the effect of persuasion is reduced on the person.

which of the following two conditions will favor a spontaneous reaction?
a) an increase in entropy and a decrease in enthalpy
b) an increase in both entropy and in enthalpy
c) a decrease in entropy and a decrease in enthalpy
d) a decrease in entropy and an increase in enthalpy

Answers

Two metals with equal mass will absorb heat according to their heat absorbing capacity.

The increase in entropy will cause the solid substance to break into multiple pieces.

When these solute particles detach from each other they will form a solution. Entropy increase will cause the temperature to increase.

Decrease in enthalpy is an exothermic reaction which releases heat from the reaction and then desired products will be formed.

A. The beginning of the reaction
B. It is constant throughout the reaction
C. The end of the reaction
D. The middle of the reaction

Answers

The answer is A
Explanation;
At the start of the reaction, when we first put magnesium in the hydrochloric acid, there is 100% of the magnesium to react with. As a result there will be more successful collisions between the reactant particles. The more successful collisions, the faster the reaction will be.

The reaction is the formation of the product from the reactants. A reaction happens quickest during the beginning of the reaction. Thus, option A is correct.

What are the factors affecting the reaction rate?

The reaction rate is the pace at which the reaction takes place and the breakdown or the combination of the reactants to produce the products. The rate of reaction depends on the concentration of the reactants.

The concentration of the reactants is in direct proportion with the rate as at the beginning of a reaction there is a higher amount of substance present than at the end.

As the reaction proceeds, the reactants get consumed and their concentration decreases. As there is a decrease in concentration the rate of the reaction converting and producing the products also decreases.

Therefore, option. the rate of reaction is fast at the beginning.

Answers

Answer:

The melting point determination may need improvement- it may not have been done properly, and make sure it was repeated at least once.

Explanation:

Given that we know the actual melting point of pure acetylsalicyclic acid to be 135°, it follows that the process followed to obtain the melting point range of 114 to 125 degrees Celsius must be inaccurate.

Answers

Answer:

See explanation

Explanation:

When dealing with the Electromagnetic Spectrum, one should remember the acronym ROYGBIV. This will apply to visible spectrum but the non-visible spectra can de logically deduced from the sequence. That is ...

   R-Red > O-Orange > Y-Yellow > G-Green > B-Blue > I-Indigo > V-Violet

In relation to the three wave properties; wavelength (λ), frequency (ν) & energy (ΔE) ...

Wavelengths => Long λ                                                                       Short λ

Frequency     => Low  ν                                                                       High ν

Energy           => Low  ΔE                                                                    High ΔE  

Note that all 'L's' are on the 'Left'

On Left => Long wavelengths, Low frequency & Low energy; the 'opposites' are on 'the other end of the list'.

Therefore for other wavelengths outside the visible spectrum set up as follows, start with visible spectrum in the middle and insert the invisible spectra of interest.

                          Long λ <= Visible (R.0.Y.G.B.I.V.) => Short λ

 λ (cm):    10¹            10⁻²          10⁻³  (10⁻⁵- 10⁻⁶)    10⁻⁷       10⁻⁹    (10⁻¹¹ - 10⁻¹³)
