Answer:

only the wave energy of the water moves

Explanation:

The plan will not work due to the fact that only the wave energy of the water moves and not the water itself.

<em>The wave motion of water does not displace the water. It is only able to transfer energy from one point to another within the medium. Hence, the ball will hardly be displaced because the water itself does not move. However, it can get to the shore with the assistance of the water current.</em>

D-Fructose is the sweetest monosaccharide. How does the Fischer projection of D-fructose differ from that of D-glucose?

nataly862011 [7]

Answer:

The projection of the Fisher projection of D-Fructose and D-glucose is that The carbonyl carbon in D-glucose is carbon 1 (aldehyde), whereas in D-fructose, the carbonyl group is on carbon 2 (ketone).

Explanation:

An aldehyde is a compound containing a functional group with the structure −CHO, consisting of a carbonyl center and

A ketone is a functional group with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents.

Barbiturates are synthetic drugs used as sedatives and hypnotics. Barbital ( = 184.2 g/mol) is one of the simplest of these drug

DanielleElmas [232]

Answer:

118.75°C is the boiling point of a solution.

Explanation:

Mass of the solute that is barbiturates = 42.5 g

Molar mass of a solute = 184.2 g/mol

Moles of solute = $\frac{42.5 g}{184.2 g/mol}=0.2307 mol$

Mass of the solvent that acetic acid = 825 g = 0.825 kg

$molality=\frac{\text{Moles of solute}}{\text{Mass of solvent}}$

Molality of the solution (m):

$m=\frac{0.2307 mol}{0.825 kg}=0.2796 m$

Elevation in boiling point is given as:

$\Delta T_b=i\times K_b\times m$

i = 1 (organic compound)

$=1\times 3.07^oC/m\times 0.2796 m=0.8585^oC$

$\Delta T_b=T_b-T$

$T_b$ = Boiling temperature of solution.

T = boiling temperature of solvent that is acetic acid=117.9°C

$0.8585^oC=T_b-117.9^oC$

$T_b=118.75 ^oC$

118.75°C is the boiling point of a solution.

<h3>What is Faraday's Law of electrolysis?</h3>

According to the first law of Faraday, the amount of substance liberated at an electrode is directly proportional to the quantity of charge passed through an electrolyte.

m = zq , where z = electrochemical equivalent

An electrochemical equivalent is the mass of the substance liberated at an electrode when 1 Columb of charge is passed through the electrolyte.

For the nickel,

$Ni^{2+} (aq) + 2e^- \rightarrow Ni (s)$
