The first whistle is louder while the second whistle has a higher pitch
Loud vs high
We assume it as an ideal gas therefore we can use the
ideal gas equation to solve the problem. The ideal gas equation is expressed as
PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.
<span>
n = PV / RT
n = </span>1.00(3L) / (<span>0.08206 atm L/mol K ) 273 K
n = 0.1339 mol

Answer:
They are placed on the periodic table based on their atomic number.
Explanation:
In the chemistry table, you can find the molecular mass and atomic number. Atomic number represents the number of the protons of an atom, and molecular mass represents the mass of the atom. The mass of an atom is made from proton and neutron. The element is made by arranging it based on the number of protons, which was the atomic number.
Answer:
the answer is in the picture
They would be neutral if their electonegativity difference was 0
