Answer:
x-rays
Explanation:
because x-rays have the highest nd it can penetrate through human body and much other things
Molar mass (formula, molecular mass) is the mass of one mole of a chemical element or a chemical compound. Molar mass is suitable and often used in chemistry because it allows for a light conversion between stoichiometric (molar) relationships represented by a chemical equation and mass relations, which are more significant in practice.
The molar mass of a compound is obtained by the sum of the atomic weights of the atoms which form a compound.
So, formula mass of P4 is:
M(P4) = 4 x Ar(P) = 4 x 31 = 124 g/mole
Answer:
Sure because I need more friends
By state of matter I assume you mean solid, liquid, gas, in which case the answer would be C.
the behaviour of molecules:
- in a solid is low energy with limited activity where molecules only vibrate, cannot mould to shape of container
- in a liquid is with moderate energy, with molecules flowing over the top of one another, and thus can mould to the shape of the container
- in a gas is high energy with much activity, molecules "fly" around the container they are in and can be compressed
