(b) the absolute temperature of the gas at which 3.33x103 mol occupies 478 mL at 750 torr,​

Answers

Answer 1

Explanation:

T=?

Given

n=3.33×10³

V=478mL=4.78L

P=750torr= 0.987 Atm

simply use the formula

PV =nRT

where R is universal gas constant

0.987×4.78= 3.33×10³×8.314×T

T = 0.000170°c

T= 273.15 K!

Answer 2

The absolute temperature of the gas at which 3.33x10³ mol occupies 478 mL at 750 torr is 1.726 × 10-³K

HOW TO CALCULATE TEMPERATURE:

The temperature of a substance can be calculated using the ideal gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)V = volume (L)n = number of moles (mol) R = gas law constant (0.0821 molK/Latm)T = temperature (K)

According to this question,

P = 750torr = 0.987 atmV = 478mL = 0.478L

0.987 × 0.478 = 3.33 × 10³ × 0.0821 × T

0.472 = 273.39T

T = 0.472 ÷ 273.39

T = 1.726 × 10-³K

Therefore, the absolute temperature of the gas at which 3.33x10³ mol occupies 478 mL at 750 torr is 1.726 × 10-³K

What is an indicator?

Indicator is defined as a chemical substance which is chemically a weak acid or a weak base which changes it's color depending upon the concentration of hydrogen ions present in the solution.They dissociate slightly in water to produce ions.

These are generally derived from plant pigments and are of slightly acidic or basic in nature.There are three types of indicators:

1) natural indicators

2) synthetic indicators

3) olfactory indicators.

These are mainly used in determination of end point of titrations. Every indicator has it's pH range in which it can perform effectively.These are usually organic compounds.

Answer:

3.43 moles

Explanation:

To convert moles into grams you must take the number of grams and divide it by the atomic mass of the compound.

in this case, grams is 151 and N2O has an atomic mass of 44.013

so your equation would look like

151/44.013=3.430804535

your answer would be 3.43 moles

Why is NH3 not considered a base under the Arrhenius definition of acids and bases?

SELECT AN ANSWER

a. It does not react with acids.
b. NH3(aq) does not contain OH- ions.
c. NH3 is considered a base under the Arrhenius definition, but not under the Bronsted-Lowry definition.
d. It does not cause a color change when mixed with an acid-base (pH) indicator.

Answers

Answer:

b. NH3(aq) does not contain OH- ions.

Explanation:

According to Arrhenius in his definition, a base is a substance that has the ability to increase the hydroxyll ion (OH-) of an aqueous solution. In other words, Arrhenius bases dissociates into OH- when dissolved in water.

According to this question, ammonia (NH3) will not be considered an Arrhenius base because it does not contain OH-. This means that ammonia (NH3) cannot dissociate into hydroxyll ion when dissolved in water.
