A sample of carbon dioxide gas that has a volume of 14.6 L at STP contains how many
Nana76 [90]

Answer:

n = 0.651 mol

Explanation:

Given data:

Volume of CO₂ = 14.6 L

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Number of moles of CO₂ = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

by putting values,

1 atm × 14.6 L = n × 0.0821 atm.L/ mol.K   × 273.15 K

14.6 L. atm =  n × 22.43atm.L/ mol

n = 0.651 mol

A dry gas at a temperature of 67.5 C and a pressure of 882 torr occupies a volume of 242.2 mL. What will be the volume of the ga
masya89 [10]

Answer:

265 mL is the new volume for the gas

Explanation:

We decompose the Ideal Gases Law in order to find the answer of this question: P . V = n . R . T

We can propose the formula for the 2 situations, where  n remains constant.

R refers to 0.082 L.atm/mol.K which is physic constant.

We convert the temperature to Absolute value:

67.5°C + 273 = 340.5 K

80°C + 273 = 353 K

We convert the volume to L → 242.2 mL . 1 L/1000 mL = 0.2422 L

We convert the pressure values to atm:

882 Torr . 1 atm/ 760 Torr = 1.16 atm

840 Torr . 1atm / 760 Torr = 1.10 atm

P₁. V₁ / T₁ = P₂ . V₂ / T₂     → Let's replace data:

1.16 atm . 0.2422L / 340.5K = 1.10 atm . V₂ / 353 K

(1.16 atm . 0.2422L / 340.5K) . 353K = 1.10 atm . V₂

V₂ = 0.291 L.atm / 1.10 atm → 0.2647 L ≅ 265 mL

What are the bad side effects of multitasking?<br> 2-4 sentences pleaze
Reil [10]

Answer:

Today, the vast majority of us multitask while using our smartphones. We play games, email, surf social media, text, and use apps and other functions while watching television, eating, doing work, or while "engaged" in a conversation with another person. Multitasking has become such a regular part of our lives that most of us believe we do it well—and few imagine it could actually be dangerous.

Explanation:

1. Multitasking is associated with harm to our brains.

2. Multitasking can lead to memory problems.

3. Multitasking can lead to increased distractibility.

4. Multitasking can make us walk into traffic.

5. Multitasking hurts your grades and the grades of those around you.

6. Multitasking can lead to falling and breaking bones.

7. Multitasking can harm your relationship.

8. Multitasking increases chronic stress.

9. Multitasking increases depression and social anxiety.

10. Multitasking makes you less productive and less efficient.
