Answer: B) 46.7% Si and 53.3% O
Explanation:
To calculate the mass percent of element in a given compound, we use the formula:
Mass of quartz 
= 5.05 g
Mass of silicon = 2.36 g
Mass of oxygen = Mass of quartz - mass of silicon = 5.05g - 2.36 g = 2.69 g
Thus the percentages of silicon and oxygen in quartz are B) 46.7% Si and 53.3% O
Option A
using verbal and nonverbal communication to show a person is listening is a critical part of listening
<u>Explanation:</u>
An adequate hearer obligation listens and recognizes the language sounds focused approaching them, know the information of the sounds, critically estimate or estimate that information, retrieve what’s implied stated, and acknowledge either orally or nonverbally to erudition they’ve earned.
Answering occasions imparting literal and nonverbal intelligence that show attentiveness and perception or a shortage thereof. We convey verbatim and nonverbal feedback while the added character is speaking and later they are ingested. Assess the trustworthiness, completeness, and quality of an information ere responding with lexical and nonverbal beacons.
N(NaCl)=8 moles
M(NaCl)=A(Na)+A(Cl)
M(NaCl)=22.99+35.45=58.44 g/moles
m(NaCl)=n(NaCl)·M(NaCl)
m(NaCl)=8moles·58.44g/moles=467.52 g
