Answer: burning paper
Explanation:
The paper burns in air to form smoke and ash. which makes it a chemical change.
Answer:
A. Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. ... Also, there are different kinds of atoms (differing by their masses) within an element that are known as "isotopes", but isotopes of an element have the same chemical properties.
B. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time.
Scientia, meaning knowledge and skill

Hello!</h2>
The answer is:
The approximate volume is 9.84 L.

<h2>
Why?</h2>
Since we are given the numer of moles, the temperature and the pressure of the gas, we can calculate the approximate volume using The Ideal Gas Law.
The Ideal Gas Law is based on Boyle's Law, Gay-Lussac's Law, Charles's Law, and Avogadro's Law, and it's described by the following equation:

Where,
P is the pressure of the gas.
V is the volume of the gas.
n is the number of moles of the gas.
T is the absolute temperature of the gas (Kelvin).
R is the ideal gas constant, which is equal to:

So, we are given the information:

Now, substituting the given information and isolating the Volume from The Ideal Gas Law equation, we have:




So, the approximate volume is 9.84 L.

Have a nice day!
