Answer:
The number of particles in the 41.8g sample of Bismuth is 12.044 × 10²³
Explanation:
We need to discuss about reduction of possible environmental damage associated with uranium mining.
There are several extraction processes involved in mining uranium as- (i) surface mining, (ii) heap leaching, (iii) underground mining and so on.
There are so many risks involved towards environment and health.
There are some improvements for long term stabilization of Uranium mining have been documented. They are as follows-back-filling and using residues for the construction of motorways, washing of soil with water, carbon treatment inclusion of new materials like room temperature ceramics for the immobilization of various contaminants, de-watering, and land encapsulation.
<u>We are given:</u>
Initial Temperature = 90°c
Final Temperature = 120°c
Heat applied(ΔH) = 500 Joules
Specific heat(c) = 0.9 Joules / g°C
Mass of Aluminium(m) = ?
<u>Change in temperature:</u>
ΔT = Final temp. - Inital Temp.
ΔT = 120 - 90
ΔT = 30°c
<u>Calculating the mass:</u>
We know the formula:
ΔH = mcΔT
replacing the values:
500 = m(0.9)(30)
500 = m(27)
m = 500/27
m = 18.52 grams
1320 calories will be got by drinking one can (330 ml) of cola.
<h3>HOW TO CALCULATE CALORIES?</h3>
Calories refers to the unit of measurement of energy consumed in food.
According to this question, one gram of sugar provides 4.0 calories of energy.
1g of a liquid substance equals 1mL. Therefore, 330mL of cola will equal (330 × 4) = 1320 calories of energy.
