Answer:
Covalent solids: Se8, Si, C
Molecular solids: HBr, CO2, P4O6, SiH4
Explanation:
A covalent solid consists only of one type of atom infinitely linked by covalent bonds to form a three dimensional rigid solid while a molecular solid consists of discreet molecules held together by intermolecular forces.
I looked it up and i saw tht it was ions and electrons.
hope this helps you!! :)
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>
Answer:
Vapor pressure of pure water: 3.1690 kPa
Explanation:
Vapor pressure is P=0.955(3.1690)=3.0263 kPa
Change in vapor pressure : 3.169-3.0263=0.142 kPa
