345 NH3 in moles is: 20.2577490294015 moles.
Ca + 2HCl = CaCl₂ + H₂
m(Ca)=60 g
c=1.25 mol/l
M(Ca)=40g/mol
v-?
m(Ca)/M(Ca)=m(HCl)/[2M(HCl)]=n(HCl)/2
n(HCl)=2m(Ca)/M(Ca)
n(HCl)=cv
cv=2m(Ca)/M(Ca)
v=2m(Ca)/{cM(Ca)}
v=2·60g/mol/{1.25mol/l·40g/mol}=2.4 l = 2400 ml
2400 milliliters of a 1.25 molar HCl solution would be needed
Answer:
When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot. To convert minutes to hours, the appropriate conversion value is 60 minutes equal 1 hour

Single replacement or single displacement reactions
Explanation:
In a single replacement or displacement reaction, the activity series is useful in predicting whether the reaction will take place or not.
- In this reaction type, one substance is replacing another.
C + DE → CD + E
- The relative positions of the two elements in the activity series provides the driving force for the single replacement reaction.
- An element high up in the series will displace one that is lower in the series because it is more reactive.
