The amount of energy a person has burned while practicing yoga for one hour can be calculated by converting kilocalories (kcal) to joules (J).
How many joules (J) of energy have they burned?One kcal is equal to 4184 J. Therefore, if a person has burned 285 kcal, they have burned 285 x 4184 = 1197140 J of energy.When the body burns energy, it does so by releasing heat. This heat is measured in joules. Any form of physical activity, such as yoga, can cause the body to burn energy, and thus release heat. The amount of energy burned during a physical activity is determined by the intensity and duration of the activity.The energy burned during yoga depends on the type of poses and exercises done, as well as the individual's level of fitness. Generally, more strenuous poses and exercises will burn more energy than gentler ones. The more intense the activity, the more energy the body will burn.When the body burns energy, it is converted into fuel for the muscles. This fuel helps maintain the body's temperature, power muscle contractions, and provide energy for cells. The energy burned during yoga is converted into ATP, which is used to provide energy to cells.In conclusion, if a person practicing yoga for one hour burns 285 kcal, they have burned 1197140 J of energy. This energy is used to power muscle contractions, maintain body temperature, and provide energy for cells.1 kcal = 4184 JTherefore, the person has burned 1189340 J of energy.To learn more about energy conversion refer to:

e) suppose you choose the initial masses so that both reactions produce pcl 3. explain how both of these chemical reactions obey the law of definite proportions, even though they produce different numbers of moles of the product. justify your answer with calculations.
The law of definite proportions states that regardless of the amount of reactants used, a chemical reaction will always produce the same proportion of products. In this case, both reactions will produce the same mole ratio of PCL3 (1:1) even though they produce different numbers of moles of the product. To demonstrate this, let's take a look at the first reaction:
Reaction 1:
2HCl + Ca3(PO4)2 → 2CaCl2 + PCl3
2 moles of HCl + 1 mole of Ca3(PO4)2 → 2 moles of CaCl2 + 1 mole of PCl3
Therefore, the mole ratio of PCL3 is 1:1.
Now let's look at the second reaction:
Reaction 2:
HCl + P4O10 → PCl3 + H3PO4
1 mole of HCl + 2 moles of P4O10 → 1 mole of PCl3 + 2 moles of H3PO4
Once again, the mole ratio of PCL3 is still 1:1. Therefore, both of these chemical reactions obey the law of definite proportions.
What is definite proportions?

Based on the molecular views, classify each substance as an atomic element, a molecular element, an ionic compound, or a molecular compound.
A molecular compound is defined as a molecule whose formula states the actual number of atoms bonded together in the molecule.
The atoms are joined to give a definite shape which is defined by the angles between the bonds and by the bond lengths. Molecular compounds can contain discrete molecules, which are held together by sharing electrons in covalent bonding.
Examples of molecular compounds are water, which contains H2O molecules; methane contains CH4 molecules; and hydrogen fluoride, which contains HF molecules.
As a rule of thumb, compounds that are involved in a metal binding with either a non-metal or a semi-metal will display ionic bonding.
Compounds can be composed with only non-metals or semi-metals and non-metals will display covalent bonding and will be classified as molecular compounds.

How do solvents affect polymers?
Solvents affect the polymers in way that they affect the strength of non-bonding interactions, which in return control the formation of supramolecular polymers in solution.
Solvents affect the polymers in way that they affect the strength of non-bonding interactions, which in return control the formation of supramolecular polymers in solution. Solvent effects and implications/parameters measured in supramolecular polymer systems are selectively reviewed. A rather new solvent scale, solvation ability (SA), which is based on the balance point between extended and stacked polymers is then introduced.
One of the most common processes used to produce polymer nanoparticles, is the solvent-displacement method, wherein the polymer is first dissolved in a "good" solvent and then the solution is mixed with an "anti-solvent". The processability of the polymer is therefore determined by polymer's structural and transporting properties in solutions of pure solvents and at the intermediate compositions.
If we put a polymer molecule into a pure solvent, three things might happen to it.
-it might curl up on itself
-it might not really notice/react with the solvent
-it might prefer the solvent used, to itself, and stretch out.

[tex]ch3ch3ch3[/tex] is the one compounds is a gas at room temperature.
What is the ideal room temperature?
Generally speaking, room temperature refers to a range of air temperatures that people favour indoors. When someone is dressed in regular indoor attire, they feel at ease. Depending on humidity, air circulation, and other factors, human comfort can go beyond this range.
Around 20°C, or 68° Fahrenheit, is usually the standard room temperature. Though it's crucial to keep in mind that different rooms will need to be heated to different temperatures, this is a good ambient temperature to aim for.
Store at 15°-25°C (59°-77°F) above room temperature. Ambient temperature: Keep your items at the temperature outside. Considering the vast range of ambient temperatures, this word is not commonly used.
Molecules with the stronger intermolecular forces are pulled tightly together to form solid at higher temperatures and that's why the freezing point is higher.
Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.
Thus, melting point and boiling point increases with increase in number of carbon atoms and also increase in intermolecular forces (like hydrogen bonding, if present).
Thus, the compound which is gas at room temperature is because it has least number of carbon atoms and absence of hydrogen bonding.

How many mol of C3H8 must be consumed via this reaction to produce a partial pressure of 3.68 atm of CO2 in a 4.00 L container at 355 K?
The number of moles of C₃H₈ that must be consumed via the given reaction is 0.168 mole
How do I determine the number of mole of C3H8 consumed?We'll begin by obtaining the mole of CO₂ produced. Details below:
Pressure (P) = 3.68 atmVolume (V) = 4 LTemperature (T) = 355 K Gas constant (R) = 0.0821 atm.L/Kmol mole of CO₂ (n) =?PV = nRT
3.68 × 4 = n × 0.0821 × 355
Divide both sides by (0.0821 × 355)
n = (3.68 × 4) / (0.0821 × 355)
n = 0.505 mole
Finally, we shall determine the mole of C₃H₈ consumed by the reaction. This is illustrated below:
C₃H₈ + 5O₂ -> 3CO₂ + 4H₂O
From the balanced equation above,
3 moles of CO₂ were obtained from 1 mole of C₃H₈
Therefore,
0.505 mole of CO₂ will be obtained from = (0.505 × 1) / 3 = 0.168 mole of C₃H₈

when chlorine is added to water, a dissociation occurs. when we add cl2 (chlorine) h2o (water), we get a reaction which leaves us with hocl (hypochlorous acid) hcl (hydrochloric acid). how much of each is created is dependent on water temperature, and especially on water ph. hypochlorous acid is the active, killing form of chlorine. this is what does the real sanitizing work in your pool water. the chlorine molecule or ion kills microorganisms by slashing through the cell walls and destroying the inner enzymes, structures and processes. when this occurs, the cell has been deactivated, or oxidized. the hypochlorous molecule continues this slash
Chlorine reacts reversibly with water to give a mixture of hypochlorous acid and hydrochloric acid.
Cl2+H2O⇔HOCl+HCl
Because of this reaction, it is able to act as a disinfectant for water sterilization.
What is sterilization?
Sterilization is a process that removes, kills, or inactivates all life forms (especially microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents, such as prions, present in or on a particular surface, object, or fluid.Sterilization can be achieved in a variety of ways, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization differs from disinfection, and pasteurization in that these methods reduce rather than eliminate all life forms and biological agents present. After sterilization, the object is referred to as sterile or aseptic.To know more about sterilization, click the link given below:
