30 ! a friend needs these answers and i don't know what to say. if you don't know the answer, ask somebody who might know, and tell @tracysparkle1 a student heats a 15.0 gram metallic sphere of unknown composition to a temperature of 98°c. the sphere is transferred to a calorimeter containing 100. ml of water at a temperature of 25.0°c. the student observes that the resulting temperture of both the water and the object is 27.1°c after the object is submerged. 1. describe, in terms of the object and the water, the flow of heat energy that took place during the experiment. 2. calculate the amount of heat energy gained by the water in the calorimeter. q = mc∆ 3. using the quantity of heat calculated in the previous question, determine the specific heat of the object.

1. Heat always flow from a region of higher temperature to a lower temperature, just like concentration gradient. So in this case, since the metallic sphere is hotter than water, so naturally heat energy flows from the metallic sphere to the water.

2. We use the formula:

Q = m C ∆T

where Q is the heat energy gained, m is mass of water, C is heat capacity of water = 4.184 J/g°C and ΔT is change in temperature

Since density of water is 1 g/mL, so mass is also 100g, therefore:

Q = 100 g * 4.184 J/g°C * (27.1°C - 25°C)

Q = 878.64 J

3. Heat gained by the water is equal to the heat lost by the metal, therefore:

Q(water) = - Q(metal)

878.64 J = - 15 g * C * (27.1°C - 98°C)

C = 0.83 J/g°C

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
