Answer:
(Highest kinetic energy)
3. Neon at 65 K and 15 atm
2. Neon at 55 K and 10 atm
4. Neon at 25 K and 5 atm
1. Neon at 5 K and 0 atm
(Lowest kinetic energy)
Explanation:
In gases, <em>kinetic energy is higher the higher the temperature is</em>. This is because the molecules have more available energy under those conditions. <u>Generally there's also an increase in kinetic energy if there's an increase in pressure</u> -assuming there's no phase changes ie. the gas condenses into a liquid-.
Answer:Hence, the bond length in HCl is 125 pm.
Explanation:
Bond length : It is an average distance between the nuclei of two bonded atoms in a molecule.
Also given that bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter-nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Beyond this if atoms come closer to each other then their will be repulsion between them.
So, the bond length between the Hydrogen and Chlorine atom in HCl molecule is :
Hence, the bond length in HCl is 125 pm.
Answer:
8.
Explanation:
Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.
If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.
16 - 8 = 8
Answer:Noble gases:
are highly reactive.
react only with other gases.
do not appear in the periodic table.
are not very reactive with other elements.
