Answer:
1/45 or 0.0222 g/s
Explanation:
rate of reaction = quantity of reactant used/time taken
= (10-8)/90
= 1/45 or 0.0222 g/s
p.s add as brainliest
Answer:
Each Hydrogen atom has one only one electron which is also its valence electron and Sulfur has six valence electrons. Thus, there are a total of eight valence electrons in H2S. In this compound, both the hydrogen atoms require one electron to make the covalent bond with Sulfur
Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Explanation:
According to the standard conversion,
Therefore, 675,000 Joules will be converted into kcal as follows.
Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Answer:
Explanation:
Hund's Rule of Maximum Multiplicity states that electrons go into degenerate orbitals of sub-orbitals(p, d and f) singly before pairing commences.
Hund's rule is useful in determining the number of unpaired electrons in an atom. Hence, it explains some of the magnetic properties of elements.
An element whose atoms or molecules contain unpaired electrons is paramagnetic.
The element whose atoms or molecules contain orbitals that are all filed up with paired electron is diamagnetic.
