Choose all of the following that have at least 1 polyatomic ion in the compound

calcium hydroxide

Na3P

lithium phosphate

ammonium sulfide

AgNO3

SrO

calcium hydroxide

lithium phosphate

ammonium sulfide

AgNO3

Explanation:

A polyatomic ion refers to an ion composed of two or more atoms in the ion. In the compounds mentioned, each contains at least one poly atomic ion.

AgNO3 contains NO3^- as its polyatomic ion

calcium hydroxide contains OH^- as its polyatomic ion

lithium phosphate contains PO4^- as its polyatomic ion

ammonium sulfide contains NH4^+ as its polyatomic ion.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
