3 L will be the final volume for the gas as per Charle's law.
Answer:
Explanation:
The kinetic theory of gases has two significant law which forms the backdrop of motion of gases. They are Charle's law and Boyle's law. As per Charle's law, the volume of any gas molecule at constant pressure is directly proportional to the temperature of the molecule.
V∝ T
Since, here two volumes are given and at two different temperatures with constant pressure. Then as per Charle's law, the relation between the volumes of air at different temperature will be
So in this case, V1 = 6 L and T1 = 80° C. Similarly, T2 = 40° C. So we have to determine the V2.
So, 3 L will be the final volume for the gas as per Charle's law.
Probably sodium Na because it has a similar atomic mass and number
Answer:
Explanation:
Information given about the element:
Number of protons = 74
Number of neutrons = 110
For the atomic number:
Neutral atoms such as this one would have their atomic number to be the same with their number of electrons and protons:
atomic number = number of protons = number of electrons
The atomic number would therefore be 74
For the mass number:
The mass of an atom is centrally concentrated within the tiny nucleus. The mass number is the sum of protons and neutrons in an atom. Protons and neutrons are nuclear particles and are called nucleons:
Mass number = number of protons + number of neutrons = 74+110=184
Is this a new element?
From the peroidic table, tungsten(W) perfectly fits this description of the atom. It has an atomic number of 74 and a mass number of approximately 184. The element is not a new element.
Is it solid, liquid, or gas?
The element is a hard metallic solid. It is a classified as a transition metal on the periodic table. Transition metals have very unique metals and are mostly solids.
