2) Solubility is how much solvent will dissolve in solute.
Answer:
An ionic bond
Explanation:
An M⁺ cation will be attracted to an X⁻ anion.
The bond formed by a cation-anion attraction is an ionic bond.
The answer is 2.78 moles of Si
The partial pressure of 0.50 Ne gas is 214.71 torr
calculation
the partial pressure of Ne = moles of Ne/total moles x final pressure
find the total moles of the air mixture
that is moles of Ne + moles of K= 0.50 + 1.20 = 1.70 moles
The partial pressure is therefore = 0.50 /1.70 x 730 = 214.71 torr
