In an experiment, equal amounts of water and soil were first heated and then left to cool. The graph shows the change in tempera

ture for each with time.
A graph with the title Change in Temperature is shown. The y axis title is Temperature in degree C and the x axis title is Time in seconds. An inverted U shaped curve labeled A is plotted. A flatter curved line labeled B is also shown plotted on the graph.

Which statement about the curves A and B is true?

Curve A represents how soil takes longer to heat and longer to cool.
Curve B represents how water takes longer to heat and longer to cool.
Curve A represents water as it heats rapidly and cools slowly.
Curve B represents soil as it heats slowly and cools rapidly.

ch sulfide (ZnS) occurs in the zinc blende crystal structure, (a) If 254 g of ZnS contains 170 g of Zn, what is the mass ratio o
Aleonysh [2.5K]

Answer:

The mass ratio of zinc to sulfide is 85:42.

2.5559 kg of Zn are in 3.82 kg of ZnS.

Explanation:

a) Mass of zinc sulfide = 254 g

Mass of zinc in a zinc sulfide sample = 170 g

Mass of sulfide in zinc sulfide sample = x

254 g = 170 g+ x

x = 84 g

The mass ratio of zinc to sulfide:

\frac{170 g}{84 g}=\frac{85}{42}

b) Mass of zincsulfide sample = 3.83 kg

The mass ratio of zinc to sulfide is 85:42.

Let the mass of zinc and sulfide be 85x and 42x respectively:

85 x+ 42 x=3.82 kg

x =0.03007 kg

Mass of an zinc= 85x=85 × 0.03007 kg= 2.5559 kg
