The answer iiiis... A: Group 8A, Period 1
<h3>
Here's why:</h3>
The way I found this doesn't have much thought or explanation--I just remember that helium and hydrogen are in period 1. The only answer choice with "period 1" is A.
You would use it in both atoms and molecules if it’s in are large quantity
Answer:
First, it is easiest if you write the compete molecular equation:
AgNO3(aq) + KCl(aq) ==> AgCl(s) + KNO3(aq) .. molecular equation.
You must also know or look up which compounds are soluble (aq) and which are not (s). In this case, silver chloride (AgCl) is not soluble. Thus, the net ionic equation is...
Ag+(aq) + Cl-(aq) ==> AgCl(s)
if an electron is passed from Ago B then Slides electrons which makes it electropositive i.e A+
D. The sand has a higher conductivity.
