SOMEONE PLZ HELP!!!!

Based on the following information, Cl2(g) + 2 e- → 2 Cl-(aq) E° = + 1.36 V Mg2+(aq) + 2 e- → 2 Mg(s) E° = -2.37 V which of the

Alex

Answer:

D) Mg(s)

Explanation:

We are given:

$E^o_{(Cl_2/Cl^-)}= 1.36V\\E^o_{(Mg^{2+}/Mg)}=-2.37V$

The substance having highest positive $E^o$ potential will always get reduced and will undergo reduction reaction. Here, chlorine will undergo reduction reaction will get reduced. Magnesium will undergo oxidation reaction and will get oxidized.

<u>Reducing agents are the species which reduces others and oxidizes itself. Thus, Magnesium will be the strongest reducing agent.</u>

When 3.24 g of a nonelectrolyte solute is dissolved in water to make 955 mL of solution at 22 °C, the solution exerts an osmotic

attashe74 [19]

Answer:

The molar concentration is 0.0529 M

We have 0.0505 moles solute

The molar mass of the solute is 64.16 g/mol

Explanation:

Step 1: Data given

Mass of the nonelectrolyte solute = 3.24 grams

Volume of water = 955 mL

Temperature = 22 °C = 295 K

Osmotic pressure = 973 torr = 973 / 760 = 1.28026 atm

Step 2: Calculate mass water

Mass water = 955 mL * 1g/mL

Mass water = 955 grams = 0.955 kg

Step 3: Calculate the molar concentration

π = i*M*R*T

⇒with π = the osmotic pressure = 1.28026 atm

⇒with i = the van't Hoff factor = 1

⇒with M = the molar concentration

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 295 K

M = 1.28026 / (0.08206*295)

M = 0.0529 M

Step 4: Calculate moles solute

Molar concentration = moles / volume

Moles solute = Molar concentration * volume

Moles solute = 0.0529 M * 0.955 L

Moles solute = 0.0505 moles

Step 5: Calculate molar mass

Molar mass = mass / moles

Molar mass = 3.24 grams / 0.0505 moles

Molar mass = 64.16 g/mol

The molar concentration is 0.0529 M

We have 0.0505 moles solute

The molar mass of the solute is 64.16 g/mol

2. How does the use of an organized binder affect the amount of homework a student turns in?

Artist 52 [7]

Answer:

This question is asking to state the hypothesis for the given scientific question. A possible hypothesis will be:

IF an organized binder is used, THEN students will turn in an increased amount of homework/more homework.

Explanation:

A hypothesis in an experiment is a testable explanation to a problem. It is a predictive statement given in order to provide a possible solution to an observed problem or scientific question. A hypothesis must be subject to testing via experimentation in order to determine whether to accept or reject it. It must not be true, instead it is just a possible answer to a problem. Hypothesis is usually written in the OF, THEN format.

In this question, a scientific question states: How does the use of an organized binder affect the amount of homework a student turns in? Based on the explanation above, a hypothesis to this question will be:

IF an organized binder is used, THEN students will turn in more homework.

What is 0.0135 moles of in AlCl3 grams? Round to 3 sig figs

Mekhanik [1.2K]

Answer: 1.80g

Explanation:

Molar Mass of AlCl3 = 27 + (3x35.5)

= 27 + 106.5 = 133.5g/mol

Number of mole of AlCl3 = 0.0135mol

Mass = 0.0135 x 133.5= 1.80g
