You always start with metal (left side of the table) and then add non metal (right side) like NaCl
if there is more than one atom then you should mention that too. so in N2O3 you say di for 2 and then Nitrogen and tri for 3 oxygen
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:
its proprionic acid which do not cause any hazardous effect on environment it only effect internal body of human if it is ingested.
Explanation:
Answer:
He is percieved in a warm climate.
Explanation:
The frog doesn't feel too cold or too hot. He is just right.
<span>No of moles of Fe = Mass / Relative molar mass of Fe. So no of moles = 89.4/ 55.845 = 1.60. The. Chemical reaction is represented as follows. 4 Fe + 3 O2 which gives 2Fe2 O3 . This means that 4 atoms of Iron reacts with 3 atoms of Oxygen to produce Iron oxide. Hence 1.60*4 moles of Fe will need to react 1.6 * 3 moles of Oxygen to produce 2 moles of Iron oxide. Hence 4.8 moles of Oxygen will be required.</span>
