Both propane and butane are used as gaseous fuels. Which compound produce more heat per gram burned? (mass of propane (C 3 H 3 )=44.1g/mol. mass of butane (C,H,0)=
58.1g/mol)(10pts)
(Hpropane-103.8kJ/mol.) (H propane-126.0kJ/mol)
Since the heat of combustion of butane is higher than that of propane, butane will produce more heat per gram when burned compared to propane.
The heat of combustion of a compound refers to the heat evolved when one mole of the compound is burnt under standard conditions. This heat of combustion increases from methane upwards.
Since the heat of combustion of alkanes increases according to increasing molar mass, butane will produce more heat per gram when burned compared to propane.

a sample of glucose contains 1.250x10^21 carbon atoms, how many atoms of hydrogen does it contain?
Answer:
Hydrogen = 2.5 * 10^21
Explanation:
Chemical Formula Glucose: C₆H₁₂O₆
One of the ways you could do this is to notice that for every carbon atom there are two Hydrogen atoms. You can state this more formally by using the formula to set up a ratio: 12/6 = hydrogen to Carbon
So if there are 1.250 * 10^21 Carbon atoms in the Glucose sample, then there will be twice as many hydrogen atoms.
H = 2 * 1.25 * 10^21 = 2.5 * 10^21 atoms
You could do this more formally by setting up a proportion.
6 Carbon / 12 Hydrogen = 1.25*10^21 / x Cross Multiply
6*x = 12 * 1.25*10^21 Combine the right
6x = 1.5 * 10^22 Divide by 6
x = 2.5 * 10^21
How many atoms are in 25.0 grams of carbon?
mol = 25/12
= 2.083 mol
1 mol = 6.02 × 10^23 atoms
2.083 mol = X
X = 2.083/1 × 6.02 × 10^23
= 1.254 × 10^24 atoms

Which of the following statements about subatomic particles is BEST supported by information in the article?
A. The motion of large objects is just as unpredictable as that of subatomic particles.
B. Subatomic particles don’t follow the same laws of physics as large objects.
C. The force of gravity acts more strongly on subatomic particles than on large objects.
D. It is easier to measure the movement of subatomic particles than the movement of large objects.
The characteristics of the subatomic particles allow to find which is the correct answer:
B) Subatomic particles don’t follow the same laws of physics as large objects.
Subatomic particles are the contributors to atoms, the main three being electrons, protons, and neutrons. The movement of these particles is described by the Schrodinger equation, the result of which is wave function.
To obtain the physical function of the wave mergers, the probability function must be constructed.
P = Ф* Ф
therefore the movement of the subatomic particulars is probabilistic at all times, when a large number of them join the mean value of this probability closer to the macroscopic movement.
Let's examine the claims.
A) False. The macroscopic motion of objects is the mean value of the microscopic motion, which with increasing size is deterministic and predictable.
B) True. Subatomic particles follow the rules of the Schrodinger equation and macroscopically Newton's second law. Inconsequently they use different laws or to describe
C) False the most important force is electrostatic.
D) false. Large particles can be measured with a ruler, but sublimation that are orders of magnitude smaller require instruments of great pressure and complexity.
In conclusion using the characteristics of the subatomic particle we can find what the correct answer is;
B) Subatomic particles don’t follow the same laws of physics as large objects.

Which functional group does the molecule below have?
Answer:
B
Explanation:
We can see here that the functional group that the molecule have is: B. Carbonyl
What is a functional group?A functional group is a specific group of atoms or bonds within a molecule that is responsible for the characteristic chemical reactions and properties of that molecule. Functional groups are the parts of organic molecules that determine their reactivity and the types of chemical reactions they can undergo.
In organic chemistry, functional groups play a crucial role in understanding the structure and behavior of molecules. Different functional groups confer distinct properties to molecules, influencing their physical properties, solubility, acidity or basicity, and interactions with other molecules.

Dentists use a soft, clay-like material to make a filling for a cavity. The filling stays soft under the light of the dentist’s lamp, but it hardens when the dentist shines an ultraviolet flashlight on it. Why does light from the ultraviolet flashlight harden the filling when light from the lamp does not?
Answer:
the clay will be melted by the light
Explanation:
because UV rays are hot but in a way, human skin can not feal pain
supose 10 atoms of carbon (c) recat with 20 atoms of oxegen (o) to from 10 molecules of carbon dioxide (co2). According to the law of conservation of matter, how many atoms are presented in this reaction?
Answer:
30
Explanation:
CO2 means that there is 1 carbon and 2 oxygens in each CO2 molecule.
If there are 10 atoms of Carbon that requires 20 atoms of oxygen.
The number of atoms present is 10 + 20 = 30 atoms of any kind present. You just need to add.

17) An ethanol solution has a concentration of 0.500M. What volume in liters of this solution
would contain 8.0 moles of ethanol?
To calculate the Molar Concentration, we will find the molar concentration by dividing the moles by liters of water used in the solution. For example, the acetic acid here is completely dissolved in 1.25 L of water. Then divide 0.1665 moles by 1.25 L to get the molar concentration, which will be 0.1332 M.
