100. mL of a gas are obtained from a reaction at 300.⁰C. What volume will the gas occupy at 100.⁰C?

Answers

Answer 1

Answer:

Answer:

The new volume is 65.1 mL.

Explanation:

We have,

Initial volume of the gas is 100 mL

Initial temperature is 300 degrees Celsius

It is required to find the volume the gas will occupy at 100 degrees Celsius. Charles law gives the relation between volume and temperature such that,

$V\propto T$

So,

$(V_1)/(V_2)=(T_1)/(T_2)$

V₂ is new volume

$V_2=(V_1T_2)/(T_1)$

V₁ = 100 mL

T₁ = 300 C = 573.15 K

T₂ = 100 C = 373.15 K

Plugging into formula we get :

$V_2=(100* 373.15)/(573.15)\n\nV_2=65.1\ mL$

So, the new volume is 65.1 mL.

why is water vapor important in weather

Answers

Water vapor is important to the weather because it creates clouds. Without clouds there would be no rain, and without rain there wouldn't be as much water now as there was 100 years ago because it wouldn't recycle. Water Vapor is very important to the weather and life as we know it.

What is considered to be one of the first series of events in the study of chemistry?

Answers

Alchemists studied chemical reactions before chemistry was a word

Final answer:

The early 19th century work of John Dalton, particularly his advancement of atomic theory and the concepts of specific mass ratios in chemical reactions, is considered one of the first major series of events in the study of chemistry. Amedeo Avogadro further developed these ideas by defining Avogadro's number.

Explanation:

The origin of chemistry can be traced back to the practice of alchemy, with attempts to understand the behavior of matter dating back more than 2500 years. However, one of the first series of significant events in the

study of chemistry began in the early 19th century with John Dalton's work in atomic theory, which was based on quantitative measurements and helped establish the concept of atoms and molecules as fundamental units of substances. Dalton was also instrumental in establishing the concept of specific mass ratios in chemical reactions, which led to the development of formula mass - the sum of the average atomic masses of all atoms in a substance's formula. This work was later extended by the Italian physicist

Amedeo Avogadro, who developed the concept of a fixed number of atoms or molecules in a mole, known today as Avogadro's number.

lines the mucus membrane
increases blood flow
keeps the brain dry and warm

Answers

I think the best answer is that the spinal fluid surrounds and protects the backbone. Also, it protects the brain from trauma. It acts as a shock absorber. It supplies nutrients to the nervous system tissue and removes waste products from the brain.
