I think the correct answer would be that there are a relatively small number of moles of HCl present. Dilute would mean that there are very few solute particles dissolved as compared to the solvent particles in the solution. Hope this helps.
Answer:
Explanation:
Given
velocity of boat with respect to river 
velocity of river is 
River is 3.5 km wide
Suppose boat leaves at an angle of 
with vertical such that it reaches exactly opposite end of initial Point
Therefore
component will balance the river Flowso that sin component helps to cross the river

Answer:
there are 3.018 kcal= 3018 cal per gram of candy
Explanation:
If the assume that the calorimeter is perfectly insulated, then all the heat released by the combustion is absorbed by the calorimeter.
Also knowing that Q= C * ΔT , where C= heat capacity of the calorimeter , ΔT= temperature change , Q = heat released by the combustion of the candy
replacing values
Q = C * ΔT = 33.90 kJ/°C * 2.46°C = 83.394 kJ
since Q is the heat released when burned all the mass m of the candy, the number of calories per gram of candy will be
q = Q/m =83.394 kJ / 6.60 g = 12.635 kJ/g
q = 12.635 kJ/g * 1 kcal / 4.186 kJ = 3.018 kcal per gram of candy
The question is unclear regarding the boat's velocity. Is it 20 m/s south relative to the water, or relative to the earth? (It is a river, after all...)
There's also the possibility that the boat's velocity relative to the river is 0. Take the south direction to be negative and north to be positive, and denote by 
the velocity of a body A relative to a body B. Under these conditions,
(B for boat, E for earth, W for water) so that the passenger's velocity relative to the earth is
(P for passenger)
or 10 m/s south.
