how many molecule are there in 24.0 L of oxygen gas at standard temperature and pressure
There are 6.44 × 10²³ molecules in 24.0 L of oxygen gas at standard temperature and pressure.
HOW TO CALCULATE NUMBER OF MOLECULES:
To calculate the number of molecules in a substance, we need the number of moles. The number of moles can be calculated using ideal gas law equation as follows:
PV = nRT
Where;
P = pressureV = volumen = number of molesT = temperatureR = gas law constantAccording to this question, oxygen gas is at standard temperature (273K) and pressure (1 atm)
1 × 24 = n × 0.0821 × 273
24 = 22.4n
n = 24 ÷ 22.4
n = 1.07moles
To calculate the number of molecules, we multiply the no. of moles by Avogadro's number (6.02 × 10²³)
no. of molecules = 1.07 × 6.02 × 10²³
no. of molecules = 6.44 × 10²³
Therefore, there are 6.44 × 10²³ molecules in 24.0 L of oxygen gas at standard temperature and pressure.

why lysine is less basic than arginine
Answer:
Arginine is the most basic among them because it contains guanidine side group, −(CH2)4NHC(=NH)NH2, which is basic. Lysine has two amine groups, which makes it overall basic because of the second isolated amine group (−(CH2)4NH2). Histidine, on the other hand, contains imidazole group, which is also basic.

Place the object in the graduated cylinder, and record the resulting water volume as "b." Subtract the volume of the water alone from the volume of the water plus the object. For instance, if "b" was 50 milliliters and "a" was 25 milliliters, the volume of the irregularly shaped object would be 25 milliliters.

ou dissolve a 2.50 g penny in 50.0 mL of HNO3. After reacting overnight, you dilute the blue solution to a volume of 100 ml. You test a sample of this solution, and find that it has an absorbance of 0.12 abs at 635 nm. i Calculate the concentration of Cu
This question is describing an spectrophotometry experiment in which the concentration of copper(II) ions has to be determined when 2.50 g of a copper-rich penny is reacted with 50.0 mL of nitric acid. In addition, the absorbance of a sample of the solution turned out to be 0.12 at 635 nm, so that the concentration was estimated as 12.8 g/L.
First of all, we must recall the Beer's law that can be written as follows:
[tex]A=ebC[/tex]
Whereas A is the absorbance of the sample, e the molar absorptivity, b the cuvette's path and C the concentration. However, this problem is not providing sufficient information to calculate the required concentration, however, similar absorbance experiments have graphed (absorbance vs concentration) calibration curves exhibiting trendlines as the one shown below:
[tex]y=0.009647x-0.003655[/tex]
Thus, since y stands for the absorbance and x for the concentration but in g/L not M (mol/L) for those experiments, we can set y equal to 0.12 so we solve for x as the concentration of the copper(II) ions in the sample:
[tex]y=0.009647x-0.003655\\\\x=\frac{0.12+0.003655}{0.009647}\\\\x=12.8g/L[/tex]
Nevertheless, it would be great if you come up with your own trendline, having clear the units for the absorbance vs concentration graph and thus double check your results because the data was not enough for the time being.

How many carbon atoms are in 11.2 ML of C3H6O
1 mL = 0.815 g
11.2 mL = X
X = 11.2 × 0.815
= 9.128 g
mole = 9.128/58
= 0.157 mole
1 mole = 6.02 × 10^23 atoms
0.157 mol = x
X = 0.157/1 × 6.02 × 10^23
= 9.451 × 10^22 atoms of C

What is the name of the compound K3N
A chemical compound is a material made up of several types of molecules. Therefore, potassium Nitride is the name of the compound K[tex]_3[/tex]N.
What is chemical compound?A compound is indeed a substance that is composed of two or more separate chemical elements mixed in a defined ratio in chemistry. When the elements combine, they react and generate chemical connections that really are hard to break. These bonds occur as a result of atoms sharing or exchanging electrons.
A chemical compound is a material made up of several types of molecules (or molecular entities) that include atoms from much more than one chemical element and are bound together by chemical bonds. Potassium Nitride is the name of the compound K[tex]_3[/tex]N.

1. Which of the following shows the process of freezing?'
A.candle wax cooling on the table
B.pouring cola over ice
C. heating a cup of water
D. particles are speeding-up and colliding more
Answer:
A. candle wax cooling on the table
Explanation:
Candle wax cooling on a table is an example of freezing because the atoms in the candle wax start to slow down as the wax cools. This is considered "freezing" because the slower an atom is vibrating then the colder it is and of course the faster an atom is vibrating then the hotter it is! :)
The diagram shows two different methods for collecting the product of a reaction. Which setup would be better for collecting a soluble gas such as ammonia?
Answer:
The setup above is used to collect hydrogen gas
Both filtration and distillation are useful ,methods to purify or separate components of a mixture. To collect soluble gas such as ammonia the best method is distillation. Thus setup 2 is better for collection of solute.
What is distillation?Distillation is the process of separation of compounds using heat and condenser. The mixture is first boiled to the boiling point of solvent. When it is heated the solvent such as water passes from the beaker on which the mixture is taken.
The steam of the solvent is then cooled in the condenser tube and then liquid is collected to a second beaker. Therefore, the solute remains in the first beaker and can be collected.
Using filtration, we can only separate solution with insoluble solutes. Using filter paper the solid from the solution can be separated out.
First set up shows the filtration method which is not applicable for collecting soluble gas like ammonia. Therefore, the second setup that is distillation is better to collect soluble gases.
