Atoms of an element have the same atomic number but different mass numbers because the atomic number only contains the amount of protons in an element.
Atoms of the same element that have different mass numbers are called isotopes.
With (AZ)X, the A is the number of protons, the Z is the number of neutrons, and the X is the electrons.
Answer:
It is negative because the enthalpy of the products is greater than the enthalpy of the reactants.
False. Many theories have been altered over the years due to new information. Scientists usually accept new evidence so they can advance their own research.
The physical properties because when it is physically changed you can identify the change. In chemical changes it sometimes deals with chemicals and stuff that include the breaking of bonds with another element.
Answer:
<h3>The answer is 25 mL</h3>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>25 mL</h3>
Hope this helps you
