If 2.00 g of mg reacts completely with 50.0 ml of hcl solution, what is the molarity of the hcl solution? mg(s) + 2hcl(aq) → mgc
Amanda [17]
The molarity of HCl is calculated as below

find the moles  of   mg used
moles = mass /molar mass

= 2.00g/24 g/mol=0.083 moles
 write the  reacting equation
Mg(s) +2HCl (aq)= MgCl2(aq) + H2(g)

by use of mole ratio between Mg to HCl  which is 1  :2 the moles of HCl is therefore
= 0.083 x2 =0.166 moles

molarity of HCl = moles of HCl/ volume in dm^3

that is 0.166/50 x1000= 3.3 M of HCl

How many kilojoules are required to convert 115.0 g of ice at 0.0 ∘c to liquid water at 32 ∘c? the heat of fusion of water is 33
Ivanshal [37]
The answer is 53.8 kJ.
Solution:There are two major steps in converting ice to liquid water. It begins with a phase change when ice melts at 0.0°C, and then a temperature change when the liquid water rises in temperature from zero to 32°C.
The amount of heat involved with the phase change melting is given by
     q = (mass of water) (ΔHfus)
        = (115.0 g)(334 J/g) 
        = 38410 J = 38.41 kJ
The amount of heat involved with temperature change is 
     q = mcΔT
        = (115.0g)(4.184J/g°C)(32°C - 0.0°C)
        = 15397.12 J = 15.39712 kJ
Summing up the two values gives the total heat required to convert ice to liquid water:
     q = 38.41 kJ + 15.39712 kJ= 53.8 kJ
