An ideal gas with an initial volume of 2. 05 L is cooled to 11 °C where its final volume is 1. 70 L. What was the temperature initially (in degrees Celsius)?

Answers

Answer 1

The initial temperature of the gas was approximately -73 °C.

To find the initial temperature of the gas, we can use the combined gas law, which states that the ratio of the initial pressure to the initial temperature is equal to the ratio of the final pressure to the final temperature, assuming the amount of gas and the gas constant remain constant.

Given:

Initial volume (V1) = 2.05 L

Final volume (V2) = 1.70 L

Final temperature (T2) = 11 °C

Rearranging the combined gas law equation, we can solve for the initial temperature (T1):

T1 = (T2 * V2 * V1) / (V1 - V2)

Substituting the given values into the equation, we find:

T1 = (11 °C * 1.70 L * 2.05 L) / (2.05 L - 1.70 L)

Evaluating the expression, the initial temperature is approximately -73 °C.

Therefore, the initial temperature of the gas was approximately -73 °C.

substances can be categorised in two ways: as an element, mixture or compound ora as a solid, liquid or gas. which
of these methods Is of most use ti chemist?​

Answers

Answer:

Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.

Explanation:

Here, we are required to determine which of these methods of classifying substances is most important to chemists.

The most useful classification of compounds to chemists is as Elements, Compounds or Mixtures

First classification of substances involves categorising them as pure substances (elements and compounds) or mixtures.

The second classification of substances is categorisation with respect to their state of matter. In essence, we can have solid, liquid or gas.

However, the most useful classification of compounds to chemists is as Elements, Compounds or Mixtures.

This is so because, the type of matter present in Elements are distinct for each element, same as for Compounds and Mixtures formed from a combination of pure substances.

Chemists focus on the diverse properties of substances, as such classification as elements, compounds and mixtures provides a wide basis for the qualitative and quantitative analysis of the properties of substances.

Classification of substances as solid, liquid or gas leaves a narrow avenue for the study of substances as the substance still contains the same type of matter, only this time in different states.

This phenomena is called an offshore breeze. At night, land is cooling faster than water; the air above the land also cools and, therefore, its density grows. As a result, the pressure above the land is greater than above the water, and the air moves from the regions with higher pressure (land) to the ones with lower pressure (water).

Explanation:

water from rain and snow that travels to streams

Please help!

Water from a rain and snow that travels to streams are examples of run off. These natural processes are part of water cycle and balance the water content in the atmosphere and hydrosphere.

What is water cycle ?

Water cycle is a geological phenomenon to balance the  water content in the atmosphere, hydrosphere and in the biosphere. The water bodies evaporate by the heat radiated by sun.

The air moisture can be restored to the land through the cooling of the vapor and pour as rain. This best illustrates the interaction between atmosphere and hydrosphere.

Rain, snow, sleet, or hail that reaches a surface stream without ever going below the soil's surface is referred to as surface runoff. It differs from direct runoff, which is runoff that directly reaches surface streams following rainfall or snowmelt. Hence option 4 is correct.

Describe the similarities and/or differences between heating and burning the magnesium metal. Did either heating or burning produce a chemical change?

Answers

Answer and Explanation:

Heating the magnesium metal is a physical change because after the process, the magnesium metal is still magnesium metal and no other substance is formed. When we heat the metal, we tranfer energy and the temperature is raised. It could include the melting of the metal, which is a change in the state of matter, but it is still a physical change because no chemical reactions occur.

Burning the magnesium metal is a chemical change because it involves the reaction with O₂ to form a different compound (a magnesium oxide).

Solid potassium chlorate breaks into potassium chloride and oxygen gas when heated up to high temperature. This is an example of a/an _______ reaction.

Answers

Answer:

es correcto bro claro eres un crak

Answer:

Decomposition Reaction

Explanation:

You can determine the type of reaction by writing out a balanced equation.

Solid Potassium Chlorate: KClO3

Potassium Chloride: KCl

Oxygen Gas: O2

Balanced Equation: 2KClO3 -> 2KCl + 3O2

By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B

Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.

explain the factor of a skeleton system ​

Answers

The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body. Altogether, the skeleton makes up about 20 percent of a person’s body weight. An adult’s skeleton contains 206 bones. Children’s skeletons actually contain more bones because some of them, including those of the skull, fuse together as they grow up. There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass. The female skeleton, on the other hand, has a broader pelvis to accommodate for pregnancy and child birth. Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton. Axial skeleton anatomyThe adult axial skeleton consists of 80 bones. It’s made up of the bones that form the vertical axis of the body, such as the bones of the head, neck, chest, and spine. The adult skull comprises 22 bones. These bones can be further classified by location: Cranial bones. The eight cranial bones form the bulk of your skull. They help to protect your brain. Facial bones. There are 14 facial bones. They’re found on the front of the skull and make up the face.Auditory ossicles The auditory ossicles are six small bones found within the inner ear canal in the skull. There are three auditory ossicles on each side of the head, known as the: malleus (hammer)incus (anvil)stapes (stirrup)They work together to transmit sound waves from the surrounding environment to the structures of the inner ear. The hyoid is a U-shaped bone found at the base of the jaw. It serves as a point of attachment for muscles and ligaments in the neck. The vertebral column is made up 26 bones. The first 24 are all vertebrae, followed by the sacrum and coccyx (tailbone). The 24 vertebrae can be further divided into the Cervical vertebrae. These seven bones are found in the head and neck. Thoracic vertebrae. These 12 bones are found in the upper back. Lumbar vertebrae. These five bones are found in the lower back. The sacrum and coccyx are both made up of several fused vertebrae. They help support the weight of the body while sitting. They also serve as attachment points for various ligament. The thoracic cage is made up of the sternum (breastbone) and 12 pairs of ribs. These bones form a protective cage around the organs of the upper torso, including the heart and lungs. Some of the ribs attach directly to the sternum, while others are linked to the sternum via cartilage. Some have no attachment point and are referred to as “floating ribs.”
