Abel was running a fever of 107 degrees Fahrenheit, what was her temperature in degrees
Celsius?
Explanation:
we know the formula to convert farenheit to Celsius
=(F-32)(5/9)
=(107-32)(5/9)
(5/9)=375/9= 41.6 degrees Celsius
How did boyle's change the way scientists make discoveries
Robert Boyle established chemistry as a discipline based on measurement, freeing it from the mysticism and alchemy that had plagued it. He introduced the concept of chemical analysis and defined elements, compounds, and mixes.
Boyle used a vacuum chamber to alter the gas's pressure in order to find the link between pressure and volume in a gas, which is now known as Boyle's law. In order to demonstrate that pressure and volume are inversely related to one another, he made detailed observations and carried out a number of experiments.
He developed a new vacuum pump and performed experiments in vacuum, they found that neither sound nor flame could exist there.

What is the primary difference between two different isotopes?
Answer:
Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.

(25 POINTS AND BRAINLIEST)What is the volume of 2 mol of chlorine gas at STP?
2.0 L
11.2 L
22.4 L
44.8 L
Answer:
44.8
Explanation:
According to standard temperature and pressure and ideal gas equation , the volume of 2 mole of chlorine gas at STP is 44.8 liters.
What are standard temperature and pressure conditions?Standard temperature and pressure are defined as a standard set of conditions required for experimental measurements which are established to allow comparison between different sets of data.
Standards which are commonly used are those International Union of pure and applied chemistry and national institute of standards and technology.These are not universally accepted standards but are the ones which are commonly used.
Standard conditions of pressure and temperature are necessary to define standard reference conditions used to express volumes of liquids and gases.
These values are important to physicists, chemists ,engineers ,pilots and navigators.On substituting values in ideal gas equation, volume= 2×8.314×273/1=44.8 liters.
Thus, the volume of 2 mole of chlorine gas at STP is 44.8 liters.

In your lab group you combined vinegar and water and observed the results shown in the picture. Choose ALL of the evidence that
supports that a chemical change has occurred.
A gas is produced.
B)The color changed.
c) Bubbling occurred.
D) The baking soda dissolved.
E) There is a change in the composition of the reactants.
ANOTHER HELP OVER HEREEEEEE PLSSSSSSS
The declaration made in the image's results indicates that a chemical shift has taken place. There occurs the creation of gas.
What occurred when you put vinegar in the water?This occurs as a result of vinegar's composition of acetic acid and water. Acetic acid and water molecules create robust connections. These bonds cause the molecules inside the solution to move more slowly than those in pure water, hastening the freezing of the solution.
Briefing:A cup of vinegar and a cup of warm water are the basic components of the vinegar cleaning solution. Grease as well as hard water stains are easier to remove with warm water. It may be best to combine the vinegar and distilled water rather than tap water when filling a spray container that will be used often.
To create a chemical reaction, what can you combine with vinegar?A chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) results in the production of salt (sodium acetate), water, and carbon dioxide gas.
