Greetings!

I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.

Hope this helps you!

Which central atom hybridization would you expect in the series bh−4, ch4, nh+4?
hoa [83]

Expected:

sp³ in all three molecules.

<h3>Explanation</h3>

The hybridization of the central atom is related to the number of electron domains around that atom.

\begin{array}{c|c|c}\textbf{Number of Electron Domains} & \textbf{Hybridization}&\textbf{Example}\\ 2 & \text{sp} & \text{C as in CO}_2\\ 3 & \text{sp}^{2} & \text{C in H}_2\text{C}=\text{CH}_2\\ 4 &\text{sp}^{3} & \text{C as in CH}_4\end{array}.

What is an electron domain?

  • An atom bonded to the central atom counts as one electron domain. That atom counts as one electron domain regardless of the bond order. One single bond counts as one electron domain. One double bond counts as one electron domain. One triple bond counts as one electron domain.
  • A lone pair of electrons count as one electron domain.

How many electron domains in BH₄⁻, CH₄, and NH₄⁺?

  • BH₄⁻: Four H atoms are bonded to the central B atom. That ensures an octet for the central B atom. No lone pairs are needed. Four electron domains from the four bonded atoms. sp³ hybridization.
  • CH₄: Four electrons domains with four H atoms and no lone pair. sp³ hybridization.
  • NH₄⁺: Four electrons with four H atoms and no lone pair. sp³ hybridization.

What is the shape of graphite​
VashaNatasha [74]

Answer:

The molecular formula lists the symbol of each element within the compound followed by a number (usually in subscript). The letter and number indicate how many of each type of element are in the compound. If there is only one atom of a particular element, then no number is written after the element.
