Based in the information given, the data that'll be affected by the error is the value of the solvent data.
It should be noted that the data that'll be affected based on the scenario given is the value of the solvent. When the preparation is kept overnight, there'll be an overflow of the solvent.
In such a case, it'll be difficult to get the correct distance that the solvent travelled. The effect on the calculated Rr is that the calculated Rr will be incorrect due to the error in solvent value.

Batteries allow us to store energy for when it’s needed, such as starting a car engine or jump-starting another car whose battery has lost its charge. But batteries cannot operate without chemical reactions. What kind of energy do you think is stored in the substances within the battery?
Answer:
Chemical energy
Explanation:
I hope this helped you!
Batteries store the energy in the form of chemical energy that chemical energy is converted into electrical energy. Chemical energy is used to stored in the substances within battery.
What is electrochemical energy ?The conversion of chemical energy into electrical energy or vice versa is called as electrochemical energy . This includes reactions transferring electrons, redox reactions .
Redox reaction in which reduction and oxidation takes place simultaneously. Reduction, when a substance receives one electron. Oxidation when a substance gives away one electron.
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
Thus, chemical energy is used to store in the substance within battery.

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

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.
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.

tornadoes form when updrafts from thunderstorms begin to _____
First answer that is correct gets brainly
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?
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.
