Answer:
You first need to construct a balanced chemical equation to describe the reaction:
KOH + HNO3 ---------> KNO3 + H2O
Work out the no. moles of HNO3 being neutralized:
Moles = Volume x Concentration = (25/1000) x 0.0150 = 0.000375 moles
From the balanced equation the molar ratio of KOH to HNO3 is 1:1 so you also need 0.000375 moles of KOH to neutralise the nitric acid
Now you can work out the volume of KOH required:
Volume = Moles/Concentration = (0.000375)/0.05 = 0.0075 dm^3 = 7.5 cm^3
The answer will be D because the reaction is what's first(A) and then it is the product that comes out.
Answer:
Jimmy wrote two expressions that are not equivalent
Explanation:
24+6=30 while 6(4+2) equals 36 because if you distribute the 6 to 4 (which equals 24) then the 6 to 2 (which equals 12) and add 24 and 12 together, you get 36. So, 24+6 =/= 6(4+2). Hopefully this is correct!
