Answer:
No of molcules(N)= 1.98×10^22
Explanation:
m=5.5, Mm= 167, NA= 6.02×10^23
Moles(n)= m/M= N/NA
5.5/167 = N/6.02×10^23
SIMPLIFY
N=1.98×10^22molecules
Answer:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). A moving car possesses mechanical energy due to its motion (kinetic energy).
Explanation:
They are arranged differently, in diamonds they are interconnected bonds and in graphite they are arranged as sheets.
The salt that its aqueous solubility most sensitive to pH would be calcium fluoride (CaF2). It is an insoluble salt which when reacted with an acid, it yields this equation:
<span>CaF2 (s) + 2 HX (aq) → 2 HF (aq) + CaX2 (aq)
</span>
Since it produces H+ and and OH- when combined with water, it is therefore sensitive to pH.
