Explanation:
probably because, X rays are used to ionise the gas molecules, which is loss of electrons, these electrons are absorbed by oil drops
The name of Pb(NO3)2 of is Lead II trioxonitrate V
The bond which exist in is Lead II trioxonitrate V ( Pb(NO3)2 ) are both ionic and covalent bond
<h3>What is a compound?</h3>
A compound is a substance which contains two or more elements chemically combined together
So therefore, the name of Pb(NO3)2 of is Lead II trioxonitrate V

Answer:
The answer to your question is: Volume = 29.79 cm³
Explanation:
Data
Density of gold = 19.3 g/cm3
Mass = 575 grams
Formula
density = mass / volume
Volume = mass/density
Volume = 575 g / 19.3 g/cm3
Volume = 29.79 cm³
I think it's less, more, more. correct me if i'm wrong
Answer:
Colours come from electrons moving between shells. The energy of light matches the energy gaps between electron shells.
Explanation:
Electrons are arranged in energy levels (shells) and there are energy gaps between shells. Electrons must be in one shell and cannot be in between. Electrons can move from one shell to another in the right conditions.
When an atoms absorbs energy from heat or light, the atom starts to move a little faster, in other words, it gets warmer. If the energy absorbed is just right to match the energy gap between shells, electrons can jump from one shell to another.
If an object is red, then the energy between gaps during light absorption is equal to the energy of the complementary light color, green.
If the object emits red light, then the energy between gaps during light emission is equal to the energy of red light.
