Neurons contribution MASS to the atom but not Charge to the nucleus !!
Answer:
116.1 a.m.u.
It is not likely that RCOOH is the pentanoic acid
Explanation:
Let's consider the generic neutralization between NaOH and a monoprotic carboxylic acid.
RCOOH(aq) + NaOH(aq) ⇒ RCOONa(aq) + H₂O(l)
The molar ratio of RCOOH to NaOH is 1:1. The moles of RCOOH are:
The molar mass of RCOOH is:
Thus, the molecular weight is 116.1 a.m.u.
Pentanoic acid has the formula C₅H₁₀O₂ with a molecular weight of 102.1 a.m.u. So, it is not likely that RCOOH is the pentanoic acid.
Answer:
C. The molecules move slower
Explanation:
Among the choices the statement about crystal lattice energy is best supported by the information in the table is <span>The lattice energy increases as the charge of anions increases, as shown by LiF and LiCl. The answer is B.
