Answer:
D
Explanation:
In the Rb atom the valence electron is farther from its nucleus than the valence electron of Li is from its nucleus
Answer:
Your question is missing some information.
But in most of the systems, potential energy and kinetic energy are inversely proportional
Hey there!
There is 1 mol of Ca atoms in 1 mol of CaSO₄
There is one atom of Ca in each molecule of CaSO₄, so in 6.022 x 10²³ molecules of CaSO⁴ there will be 6.022 x 10²³ atoms of Ca.
Hope this helps!
Answer:
The kinetic theory of matter explains that all matter is made of particles which are constantly moving/have energy. The energy varies depending on the temperature of the matter, therefore determining if the matter is solid, liquid, or gas. When the energy of a particle is increased or decreased, a phase change can occur.
