From the given, the characteristics that apply for solids are fixed volume, non-compressible, rigid, fixed shape.
<u>Explanation:</u>
Solids are one of the things where the molecules are tightly bonded and packed with strong forces so that the solids reach stable dimensions, stable shape and rigidity, and these are compressible because of strong bonds formed by the inadequate space between the molecules.
Solids are not compressible or easily compressible, because the molecular space between the molecules is too small.
<span>From the chemical equ
NO2 + 02 gives N2O4 .
The above means that 1 mole of No2 produces1 mole of N204.
Hence 0.54 mole of NO2 will also produce 0.54 mole of N2O4.</span>
Answer:
A
Explanation:
collision theory is a theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another
I believe it would be the last one because you can use the molar mass of HCl to find the number of moles, then use Avogadro’s number to find the number of atoms
Hope this helps!
