Based on the principle of conservation of energy, the heat capacity of the calorimeter is calculated using the formula:

c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)

<h3>What is a calorimeter?</h3>

A calorimeter is an equipment used to determine heat of reaction.

The calorimeter works on the principle of conservation of energy:

heat gained = heat lost

Quantity of heat energy is calculated using the formula below:

q = mass × heat capacity × temperature difference

In the experiment, the following procedure is followed:

Mass of the hot water, cold water and calorimeter are recorded
temperature of the hot water is recorded
temperature of the the cold water and calorimeter is recorded
final temperature of the mixture is recorded
heat capacity of the calorimeter is calculated using the formula: heat gained by calorimeter and cold water = heat lost by hot water.

Assuming that;

mass of hot water = m1
mass of cold water =m2
mass of calorimeter = m3
initial temperature cold water and calorimeter = t1
final temperature of mixture = t2
heat capacity of water = w
heat capacity of calorimeter = c

Therefore, the heat capacity of the calorimeter is calculated using the formula:

c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)

In clinical brachytherapy, the supervision of radio elements and dose interpretation are performed by the therapeutic __________

Alex_Xolod [135]

Answer:

Radiation oncologist.

Explanation:

Cancer is one of the most deadly disease and half of the world population died due to cancer every year. Cancer might occur due to the mutation in the genes that control the cell cycle.

The oncologist may be defined as the individual that has specialized in the cancer and its treatment. The different radiation might use to kill the cancerous cell and the radio elements are administered in the drugs used during the chemotherapy.

Thus, the answer is radiation oncologist.

How many moles are in 6.21x1025 atoms of magnesium oxide?

Rasek [7]

Answer: 55.56 moles of MgO

Explanation:

1 mole = avogadro number

if 6.21x10^25 atoms then molecules of MgO (equal numbers of Mg and O atoms)

= 0.5*6.21x10^25 = 3.105 molecules of MgO

So moles of MgO = 0.5*6.21*10^25/avogadro number = 55.56

In an exothermic reaction, energy may be released to the surroundings in the form of?

djverab [1.8K]

Answer:

All of the above

Explanation:

Exothermic reactions release energy usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning hydrogen)
