Answer:
PCl3
Explanation:
The molecular formular of a compound shows the exact number of atoms of elements present in the compound. In this illustration, there is one atom of P and 3 atoms of Cl.
The formular is given as; PCl3
Answer:
See explanation
Explanation:
Calcium is divalent. This means that it donates two electrons during ionic bond formation. Since chlorine atom can only accept one electron during ionic bond formation, two chlorine atoms must accept the two electrons donated by calcium.
For this purpose, each time CaCl2 is formed, there must be two chlorine atoms for each calcium atom.
Punnett squares were developed to see what the variety of genetic outcomes could possibly be
Answer: 150N
Explanation:
The formula to calculate the force will be the mass multiplied by the acceleration. In this case, mass = 15kg and acceleration = 10m/s². Therefore, force will be:
= Mass × Acceleration
= 15 × 10
= 150N
The force is 150Newton
We have Boltzmann's equation S = k ln W
Boltzmann's constant k = 1.381 x 10^-23 J/K
W = Number of absorption sites
At W = 484, Entropy S1 = 1.381 x 10^-23 ln 484 = 8.537 x 10^-23 J/K
At W = 729, Entropy S2 = 1.381 x 10^-23 ln 729 = 9.103 x 10^-23 J/K
Change of Entropy = S2 - S1 = 0.566 x 10^-23 J/K
