Answer:
81.04°C
Explanation:
Heat loss by water = Heat gained by Aluminum
Heat loss by water;
H = MCΔT
ΔT = 100 - T2
M = 580g
c = 4.2
H = 580 * 4.2 (100 - T2)
H = 243600 - 2436T2
Heat ganed by Aluminium
H = MCΔT
ΔT = T2 - 24
M = 900g
c = 0.9
H = 900 * 0.9 (T2 - 24)
H = 810 T2 - 19440
243600 - 2436T2 = 810 T2 - 19440
243600 + 19440 = 810 T2 + 2436T2
263040 = 3246 T2
T2 = 81.04°C
Assumption;
Assume that energy diffuses throughout the pan and water so that all parts reach the same final temperature.
1 mole of particles = 6.02*10²³
8.59 *10²³atoms*(1 mol/6.02*10²³ atoms) = (8.59/6.02) mol
M(Cl)=35.5 g/mol
(8.59/6.02) mol*35.5 g/mol=50.7 g
This technique has no effect on the percent of acetic acid in the vinegar, as deionized water does not affect the number balance of H+ hydronium ions or OH- hydroxide ions. This is done just to make the endpoint reading easier.
Answer:
pasture/range
Explanation:
this is because more than 1/3 of the country's land is being used for this mean alone.
