Answer:

Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water

Explanation:

How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.

There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.

A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher

Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least

Explanation:

The cold drink chiller is a cold substance which is inserted into a bottle of drink which contains warm liquid particles at a particular temperature.

Once the drink chiller is inserted, the liquid molecules around the drink chiller become cooler, denser and sink away from the drink chiller. Other warmer, less dense molecules of the liquid drink now replaces them around the drink chiller.

A convection current is thus set up for as long as the drink chiller is working.

Answer:

2.49moles

Explanation:

To calculate the number of moles (n), of iron (Fe) in 1.5 × 10²⁴ atoms, we divide the number of atoms by Avogadro's number (6.02 × 10²³).

That is, n = N ÷ nA

Where;

n = number of moles (mol)

N = number of atoms

nA = Avogadro's constant

n = 1.5 × 10²⁴ ÷ 6.02 × 10²³

n = 1.5/6.02 × 10(²⁴ - ²³)

n = 0.249 × 10¹

n = 2.49moles

The half-reaction is Zn → Zn⁺² + 2e⁻ which is most likely occur at the anode to produce a spontaneous reaction.

Hence, option (B) is correct answer.

A reaction which occurs without the intervention of outside is called Spontaneous reaction.  The reaction is Spontaneous when the Δ G < 0 and [tex]E^{\circ}_{\text{cell}}[/tex] > 0.

Cathode where the reduction occurs. Anode where the oxidation take place.

Cathode: Ni⁺² + 2e⁻ → Ni

Anode: Zn → Zn⁺² + 2e⁻

______________________

Zn + Ni⁺² → Zn⁺²  + Ni

The above reaction is spontaneous reaction.

Thus, from the above conclusion we can say that half-reaction is Zn → Zn⁺² + 2e⁻ which is most likely occur at the anode to produce a spontaneous reaction.

Hence, option (B) is correct answer.

Answer:

2, 1, 2,1

Explanation:

The chemical equation of the reaction given in this question is as follows:

AgNO3 + CuCl2 → AgCl + Cu(NO3)2

The reaction is between silver nitrate (AgNO3) and copper (I) chloride (CuCl2) to form silver chloride (AgCl) and copper nitrate (Cu(NO3)2.

However, this above equation is not BALANCED because the number of atoms of each element on both sides of the equation does not equate i.e. are not the same. To balance the equation, we have to make use of COEFFICIENTS, which are numbers used in front of each element in order to balance the equation.

The balanced equation is as follows:

2AgNO3 + CuCl2 → 2AgCl + Cu(NO3)2

From the above balanced equation, we can observe that coefficients used to balance the equation is in the order: 2, 1, 2,1

Answer:

A) oxidizing agent is SO2

B) NaClO is the oxidizing agent

Explanation:

A) This is a redox reaction in which oxidation and reduction occur simultaneously.

Thus, in 2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s);

H2S is reduced as follows;

H2S → S + 2H+ + 2e−

We can see that SO2 has been reduced while H2S gets oxidized since it has changed state from - 2 to 0 . Thus sulphur dioxide is the oxidizing agent.

B) SO2(g) + H2O(l) + NaClO(aq) -> NaCl(aq) + H2SO4(aq)

In this, SO2 undergoes oxidation and NaClO is the oxidizing agent

The reaction that occurs at the cathode of a given galvanic cell is:

Cu²⁺  + 2e⁻  → Cu

A galvanic cell can be defined as an electrochemical cell that converts the chemical energy of spontaneous redox reactions into electrical energy. The galvanic cell makes use of chemical reactions to generate electrical energy.

A galvanic cell consists of two half-cells and a salt bridge. Each half-cell further contains an electrode dipped into an electrolyte. When both electrodes are dipped in the same electrolyte, then there is no need for a salt bridge.

At the anode, an oxidation reaction occurs at this electrode. At the cathode, reduction occurs at this electrode. The anode has a negative potential with respect to the solution while the cathode has a positive potential with respect to the solution.

As in the question, the reduction of Cu²⁺ has a positive reduction potential. Therefore, the reduction of the copper will occur at the cathode.

Answer:

13924g/mol is the molar mass of the protein

Explanation:

What is the molar mass of the protein.

The osmotic pressure of a solution, π, is defined as:

π = c*R*T

Where π is osmotic pressure = 2.054torr* (1atm/760torr) = 2.70x10⁻³atm

c is molar concentration of the protein,

R is gas constant = 0.082atmL/molK

And T is absolute temperature = 298K

Solving the molar concentration:

c = π / RT

c = 2.70x10⁻³atm / 0.082atmL/molK*298K

c = 1.106x10⁻⁴ moles protein / L

The moles of protein in 150mL = 0.150L:

0150L * (1.106x10⁻⁴ moles protein / L) = 1.659x10⁻⁵ moles protein

The molar mass is the ratio of mass and moles:

0.231g / 1.659x10⁻⁵ moles protein =

Answer:

Aluminum; [Ne]3s²3p¹

Arsenic; [Ar]3d¹⁰4s²4p³

Explanation:

Aluminum

From the periodic table, we have that aluminum, Al, is located in period 3, and group 3A of the periodic table

Therefore, the noble gas that comes before aluminum in the periodic table is neon Ne

The electronic configuration of aluminum is 1s²2s²2p⁶3s²3p¹

The electronic configuration of neon is 1s²2s²2p⁶

Therefore, the electronic configuration of aluminum in noble gas notation (Ne) is therefore;

[Ne]3s²3p¹

Arsenic

Arsenic is located after argon, Ar on the periodic table

The electronic configuration of arsenic is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³

The electronic configuration of argon is 1s²2s²2p⁶3s²3p⁶

The electronic configuration of arsenic in noble gas notation (Ar) is given as follows;

[Ar]3d¹⁰4s²4p³

Answer:

London dispersion,hydrogen bond, dipole-dipole,dipole-induced dipole.

Explanation:

London dispersion < hydrogen bond < dipole-dipole < dipole-induced dipole.

Intermolecular forces are the forces which mediate an interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighbouring particles.

The London dispersion force is a temporary attractive force that occurs when the electrons in two adjacent atoms make atoms form temporary dipoles.

A hydrogen bond is an intermolecular force that occurs with a special type of dipole-dipole attraction.

Dipole-dipole forces are the forces between the positive side of one polar molecule and the negative side of another polar molecule.

A dipole-induced dipole attraction is a weak attraction that occurs when a polar molecule produces a dipole in an atom or in a nonpolar molecule by arranging of electrons in the nonpolar species.

Hence intermolecular forces from weakest to strongest are:

London dispersion < hydrogen bond < dipole-dipole < dipole-induced dipole.

Explanation:

Answer:  Write down the chemical equation first;

2H2 + O2 —-> 2H2O

2. Since the mass is given, use it to calculate the mole for each reactant;

mole = mass / molar mass

mole of H2 : 8/2 = 4 mole

mole of O2 : 30/16(2) = 0.9375 mole

Now, if you're not sure which reactant to use to calculate the mass of H2O using ratio since both answer are different, find the limiting reactant.

From the equation;

2 mol of H2 -> 2 mol of H2O

4 mol of H2 -> (4*2)/2 = 4 mol of H20

______________________________________

1 mol of O2 -> 2 mol of H2O

0.9375 mol of O2 -> (0.9375*2)/1 = 1.875 mol of H2O

Let's take a look at both numbers. Since H2 produces more water than O2, O2 will be the limiting reactant as it has the least mole of H2O. So now we are going to use O2 as our limiting reactant. Use the formula to calculate mass of water using mole.

mass of H2O : 1.875*(16+2) = 33.75 g
