(2) gains 12 moles of electrons, easy, because it must retain the same mass in a balanced equation, so if there is no exterior mention of any electrons, such as the notation +12e-, than we must assume that the Oxygen took it at any rate.
Answer:
A) 1.3 × 10⁻⁵ mol/L
Explanation:
Step 1: Write the balanced equation for the solution of AgCl
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
Step 2: Make an ICE Chart
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
I 0 0
C +S +S
E S S
If we replace the solubility (S) in the Ksp expression, we get,
Ksp = [Ag⁺] [Cl⁻] = S × S = S²
S = √Ksp = √1.8 × 10⁻¹⁰ = 1.3 × 10⁻⁵ mol/L
Answer:
The coronavirus has RNA?
Explanation:
Coronaviruses are important human and animal pathogens and contain an extraordinarily long (27-31 kb) RNA genome. Its RNA synthesis involves complex mechanisms of regulation, similar to those of DNA viruses. In this treatise, mouse hepatitis virus (MHV) is used as a model for the discussion of the mechanism of viral RNA synthesis. We show that MHV RNA synthesis requires interactions of multiple RNA components, which are likely mediated by protein-RNA and protein-protein, as well as RNA-RNA, interactions. This virus also provides a unique example of a discontinuous transcription mechanism, which involves a trans-acting RNA component. Finally, study of the cis-acting signals for the various steps of RNA synthesis revealed an insight into the regulation of viral RNA synthesis. This discussion suggests that the regulation of RNA synthesis in coronavirus is more complex than previously thought possible for RNA viruses. Coronavirus RNA transcription and replication may serve as a paradigm of RNA synthesis for RNA viruses in general.
The speed of light is (2.998x108/3.00x109) meters per second = 300,000 kilometers per second.
going down the the periodic table, the number of shells increases resulting in an obvious increase in the atomic radii of the elements
