check the attached image. hope it helps

Explanation:

a. What does mol/L mean? mol/L means Molar Concentration

b. Describe in your own words how mol/L compares to grams/liter. (similarities and differences)

Similarities: mol/L and grams/liter both are units of concentration.

Differences:

mol/L concentration says how many moles of solute are present in 1L of solution.

grams/liter concentration says how many grams of solute are present in 1L of solution.

3. Describe at least 2 ways in the simulation to change each of the parameters:

a. Volume of solution= evaporating or adding more water

b. amount of solute=reducing the water or evaporating more water

c. Concentration of solute in solution = evaporating or adding more solute

taurus [48]

Answer:

No, there is no evidence that the manufacturer has a problem with underfilled or overfilled bottles, due that according our results we cannot reject the null hypothesis.

Explanation:

according to this exercise we have the following:

σ^2 =< 0.01 (null hypothesis)

σ^2 > 0.01 (alternative hypothesis)

To solve we can use the chi-square statistical test. To reject or not the hypothesis, we have that the rejection region X^2 > 30.14

Thus:

X^2 = ((n-1) * s^2)/σ^2 = ((20-1)*0.0153)/0.01 = 29.1

Since 29.1 < 30.14, we cannot reject the null hypothesis.

Calculate the volume of the gas, in liters, if 1.35 mol

Alina [70]

Answer:

22.8 L

Explanation:

Step 1: Given data

Moles of the gas (n): 1.35 mol

Pressure of the gas (P): 1.30 atm

Temperature (T): -6°C

Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15 = -6 + 273.15 = 267 K

Step 3: Calculate the volume of the gas

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 1.35 mol × (0.0821 atm.L/mol.K) × 267 K / 1.30 atm

V = 22.8 L

LekaFEV [45]

Answer:

3) O(g) is an intermediate; 2O3(g)→3O2(g)

Explanation:

The decomposition of ozone to yield oxygen occurs in a sequence of steps. The various non-elementary reactions involved constitute the reaction mechanism. In the sequence of reaction steps O(g) serves as an intermediate.

The overall reaction involves the conversion of two moles of ozone to three moles of oxygen as shown in the answer. Thus the O(g) is merely a reaction intermediate.
