Answer:
c. AgNO₃(aq) + NH₄Cl(aq) ->AgCl(s) + NH₄NO₃(aq)
Explanation:
We have to follow the <u>solubility rules</u> to check the states of each compound.
-) All the cholride salts are soluble EXCEPT those also containing: lead, silver or mercury. 
-) All the nitrate 
and ammonium salts 
are soluble.
With this in mind 
, 
and 
would be soluble, so we have to use the <u>aqueosus state (aq).</u>
The 
then would have a <u>solid state (s)</u>.
Answer:
<h3>The answer is 0.03 moles</h3>
Explanation:
To find the number of moles given the number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2 × 10²² molecules of water
We have
We have the final answer as
<h3>0.03 moles</h3>
Hope this helps you

Radioactivity or radioactive decay is the process that occurs when unstable isotopes or atoms release energy by emitting radiations such as ,gamma radiations, alpha radiations and beta radiations to attain stability. Therefore, in this case decay is likely to occur when a given atom has two many neutrons in its nucleus in order to attain stability.
<span>he density of a material is defined as its mass per
unit volume. In this example, each volume of water is different and
therefore has a specific and unique mass. The mass of water is expressed
in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm 3), or milliliters (mL).</span>
