Explanation:
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.

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.

milk is heterogeneous mixture why
Answer:
Milk is essentially a colloidal dispersion of fat in water. ... However, the fact remains that the fat and water components cannot be mixed together from a solution. There are therefore, two distinct immiscible liquid phase's present, which is why it is a heterogeneous mixture.

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

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.
Hope It Helpz(◕ᴥ◕)A student borrows $10,000 from a bank but ends up paying $13,000 on the
loan over the next five years. How much interest did the student pay?
The student paid an interest of $3,000 over the next five years.
HOW TO CALCULATE INTEREST:
The interest on a borrowed amount of money can be calculated by subtracting the principal from the amount paid over time. That is;
Interest = principal - amount
According to this question, a student borrows $10,000 from a bank but ends up paying $13,000. This means that the principal is $10,000 while the amount is $13,000. The interest is calculated thus;
Interest = $13,000 - $10,000
Interest = $3,000
Therefore, the student paid an interest of $3,000 over the next five years.

Answer:
In the final solution, the concentration of sucrose is 0.126 M
Explanation:
The number of moles of solute in the volume taken from the more concentrated solution will be equal to the number of moles of solute in the diluted solution. Then, the concentration of the first solution can be calculated using the following equation:
Ci · Vi = Cf · Vf
Where:
Ci = concentration of the original solution
Vi = volume of the solution taken to prepare the more diluted solution.
Cf = concentration of the more diluted solution.
Vf = volume of the more diluted solution.
For the first dillution:
26.6 ml · 2.50 M = 50.0 ml · Cf
Cf = 26.6 ml · 2.50 M / 50.0 ml
Cf = 1.33 M
For the second dilution:
16.0 ml · 1.33 M = 45.0 ml · Cf
Cf = 16.0 ml · 1.33 M / 45.0 ml
Cf = 0.473 M
For the third dilution:
20.0 ml · 0.473 M = 75.0 ml · Cf
Cf = 20.0 ml · 0.473 M / 75.0 ml
Cf = 0.126 M
In the final solution, the concentration of sucrose is 0.126 M

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.
