Explanation:
After the solid is recoverd by decanting the liquid, some solvent particles may still adhere to the solid.
In order to remove the solvent that may have adhered to the solid completely , the solid is washed before it is now dried.
Your Answer is C because trees and monkeys are organisms cause there living.
Answer:
2.1 x 10⁻².
Explanation:
- Generally, the equilibrium constant (Keq) is the product of the concentration of the reaction products divided by the product of the concentration of the reaction reactants, each term is raised to a power equal to its coefficient in the balanced chemical reaction.
- For the given reaction: 2HF → H₂ + F₂,
Keq = [H₂][F₂] / [HF]²,
Keq = [H₂][F₂] / [HF]² = [8.4 x 10⁻³][8.4 x 10⁻³] / [5.82 x 10⁻²]² = 2.1 x 10⁻².
Answer:
Yes, this theory supports the inert nature of noble gases.
Explanation:
Noble gases already attain octet state stability, by having their outer shells completely filled with electrons. This makes them unable to take part in chemical reaction (by lose, gain or sharing of electrons).
Flammability occurs when matter burns through combination with oxygen, and changes to a different substance.
I hope this explanation is clear, let me know if I can be of further assistance.
