A dependent variable (y) is a variable that relies on the x value. i hope this helps!!!
Answer:
c .force and gravity hope this the right answer
Answer:
32.04°C will be the final temperature of the solution.
Explanation:
Moles of potassium chloride = 0.200 mol
MAs sof KCl= 0.200 mol × 74.5 g/mol= 14.9 g
Enthalpy of solvation of potassium nitrate =
Energy released when 0.200 moles of KCl is dissolved in water = Q
(1 kJ = 1000 J)
Heat released on dissolving 0.200 moles of KCl is equal to heat absorbed by water = Q
Mass of solution , m= 80.0 g +14.9 g = 94.9 g
Specific heat of water = c = 4.184 J/g°C
Initial temperature of the water =
Final temperature of the water =
32.04°C will be the final temperature of the solution.
<span>The
statement ‘A car requires brakes in order to stop’ follows Newton’s first law
of motion: the Law of Inertia. The car will stop if there is a brake. This is
similar to the first law wherein an object stays at rest unless a force is
acted upon it.</span>
