A disadvantage of disposing of waste polymers through _____ is that they must first be separated, which can be expensive. What is the missing word in this sentence?

Answers

A disadvantage of disposing of waste polymers through recycling is that

they must first be separated.

Recycling is the process of forming new polymers and compounds as against their disposal .

Recycling involves separating the items into various sections such as paper,

plastic , metal etc. This is because they both undergo different recycling

processes.

The disadvantage of this process is that it's time consuming and also

expensive as a great amount of time and man power is needed to

separate the waste items.

In an experiment trying to dissolve sugar in water, a person boils water in a pot on the stove and then puts the water and the sugar in a cup. That person times how long it takes to dissolve the sugar.

Answers

According to the concept of solubility, boiling water and then adding sugar to it will take longer time to dissolve than adding water and sugar together to boil as thermal energy requires to dissolve sugar will be less.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

How can you improve your ability to see the indicator color change at the endpoint of a titration?.

Answers

Answer: Place a piece of white paper under the analyte flask throughout the titration

Explanation:

The end point of titration can be made easy by the use of indicators. But we have to be keenly observe for each drop from the burette because, the colour change will be sudden for a drop.

What is titration?

Titration is an analytical technique used to determine the unknown concentration using a standard reagent of known concentration. The standard reagent of known concentration is called titrant and the  one to be determined is called analyte.

Usually analyte is taken in a conical flask and titrant in a burette. The end point of titration is the point at which the reaction is completed in perfect stoichiometry.

In acid-base titrations, the indicators used having different colors in different pH. Hence, the indicator in the analyte will change in color when the acidity of the medium changes. We have to observe keenly for the color change because it happens for any drop.

The adding of titrant from the burette must be dropwise and thus we can get a time to notice the sudden colour change of indicator.

Use this picture to explain that an electrically charged object can attract an uncharged object without any contact. Your answer should be at least three sentences long.

Answers

Answer:

It is because the object that is charged attracts the uncharged because it is giving electrons and passing it on to the object. As shown in the image the balloon is attracting the paper that is not charged. Actually telling,the charged object will cause the uncharged object to become charged, with a positive charge on one side and a negative charge on the other side. This process is called induction.

Explanation: Pls Mark Brainliest

Answer:

Positive and negative charges

Explanation:

When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. In the figure, we can see that the ballon has charges which produces opposite charges in the paper which is uncharged.

tornadoes form when updrafts from thunderstorms begin to _____

First answer that is correct gets brainly

Answers

Tornadoes form when updrafts from thunderstorms begin to interact with strong wind shear and develop a rotating column of air.

Updrafts are powerful vertical currents of air that occur within thunderstorms, caused by the rapid heating of the Earth's surface and the subsequent convective process. These updrafts carry warm, moist air upward, creating a conducive environment for the formation of severe weather phenomena.

When the updrafts encounter wind shear, which is the change in wind speed and direction with height, it can lead to the development of horizontal vorticity. Wind shear creates a rotating motion within the storm, where air at different heights starts to rotate at different speeds, generating a horizontal spin.

As the updraft continues to intensify, it tilts the rotating column of air from horizontal to vertical, forming a mesocyclone. The mesocyclone is a critical component in tornado formation. It acts as a localized area of strong rotation within the storm, extending from the cloud base to the mid-levels of the atmosphere.

Under specific conditions, such as the presence of a strong updraft, a well-developed mesocyclone, and further enhancement from other atmospheric factors, the mesocyclone can contract and intensify into a tornado. The process is complex and influenced by various meteorological factors, but the interaction between updrafts, wind shear, and the development of rotation plays a fundamental role in tornado formation.

The burning of fossil fuels contributes to the addition of greenhouse gases to the atmosphere. These gases trap thermal energy in the Earth’s atmosphere. Which of the following would be the most reasonable changes that could result from an increase in the burning of fossil fuels?

Answers

Explanation:

The burning of fossil fuels contributes to the addition of greenhouse gases to the atmosphere. These gases trap thermal energy in the Earth's atmosphere.

The materials which contain hydrocarbons which are generated from the remains of decay of plants and animals that are buried underground for many years are called fossil fuels.

What causes by burning fossil fuels?

The burning of fossil fuels can affect the environment, climatic conditions and human health. The burning of fossil fuels produces large amount of green house gases like CO₂, CH₄, etc. The increase in the amount of green house gases increases the heat and temperature of the earth's surface which leads to global warming.

The increase of temperature due to global warming can cause rise in the sea level, the glaciers of the earth will melt and coastal areas will be submerged under water due to this.

The burning of fossil fuels also releases toxic gases like SO₂, NO₂ which can cause acid rain and the emission these gases causes air pollution.

Thus the burning of fossil fuels has adverse effects.
