If 0.45 mole oxygen gas occupies a volume of 1.5 L, what volumes will 2.0 moles of oxygen gas occupy at the same temperature and pressure?
please don't send YouT8ube link i need a solution
Answer:
1. How many moles of oxygen will occupy a volume of 2.5 liters at 1.2 atm and 25° C? PV = V (1.2 n. 0821) (298) = 123 mols 2.
2.0 moles of oxygen gas will occupy a volume of 6.67 L at the same temperature and pressure.
Moles is a unit of measurement used in chemistry to express the amount of a substance. It is a counting unit that represents the number of particles, such as atoms, molecules, or ions, in a given sample.
One mole of a substance is defined as the amount of that substance that contains Avogadro's number of particles, which is approximately 6.022 x 10²³. This number is based on the concept that atoms, molecules, and ions are extremely small and difficult to count individually, so using moles allows for a more practical and convenient representation of quantities.
Given:
Moles of oxygen gas (initial) = 0.45 mol
Volume of oxygen gas (initial) = 1.5 L
Moles of oxygen gas (final) = 2.0 mol
Volume of oxygen gas (final) = ?
Using the principle of molar volume, we can set up the following ratio:
(0.45 mol / 1.5 L) = (2.0 mol / V)
V = (1.5 L × 2.0 mol) / 0.45 mol
V = 6.67 L

why compounds with weak molecular forces are usually gases.
Molecular substances tend to be gases because the intermolecular forces of attraction are comparatively weak. You don't have to break any covalent bonds in order to melt or boil a molecular substance.
The longest intermolecular separation and hence the strongest intermolecular pressure of attraction can be found in the gaseous state of matter.
Although solids' intermolecular interactions were sufficient to maintain themselves in locked places, gases often have weak intermolecular forces that cause them to remain considerably separated. The gases possess greater intermolecular space than solids as a result of these weak forces.

The side of a cube is found to be 127.58 mm and its mass is found to be 7.3 kg. Determine the density of this cube in g/mL.
Answer:
3.5154 g/mL
Explanation:
You will need to use the equation Density = Mass/Volume. You are given mm(can be used to find volume) of a cube and kg(mass). Since your answer is in g and mL we should convert it to those sizes. First we want cm so we will divide the 127.58 mm to cm getting 12.758 cm. We want to cube it since we are finding the whole area of a cube( 12.758*12.758*12.758) which will equal 2076.58 cm^3. We know that 1 mL is equal to 1 cm^3, so we can take our 2076.58 cm^3 and label them as mL(which is what we want). Then we know that there are 1000g in 1 kg, so if we multiply the 7.3 kg, we get 7300g. Finally use the equation Density = Mass/Volume to get your answer. 7300g/2076.58mL = 3.5154 g/mL.

Which of the following is a completely elastic collision? A. a ball rebounds against a wall, reversing its direction, but at only half the speed. B. Two balls collide, stick to each other, and move together after the collision. C. Two balls collide and move at a right angle to each other after the collision at a reduced speed. D. Two balls collide head on, each reversing its direction and traveling at half the speed. E. A ball with velocity v collides with a ball at rest; after the collision the first ball is at rest and the second ball has velocity v. I will mark brainliest
Answer:
Answer E.
For a collision to be completely elastic, there must be NO LOSS in kinetic energy.
We can go through each answer choice:
A. Since the ball rebounds at half the initial speed, there is a loss in kinetic energy. This is NOT an elastic collision.
B. A collision involving sticking is an example of a perfectly INELASTIC collision. This is NOT an elastic collision.
C. A reduced speed indicates that there is a loss of kinetic energy. This is NOT elastic.
D. The balls traveling at half the speed after the collision indicates a loss of kinetic energy, making this collision NOT elastic.
E. This collision indicates an exchange of velocities, characteristic of an elastic collision. We can prove this:
Let:
m = mass of each ball
v = velocity
We have the initial kinetic energy as:
KE = \frac{1}{2}mv^2 + 0 = \frac{1}{2}mv^2KE=21mv2+0=21mv2
And the final as:
KE = 0 + \frac{1}{2}mv^2 = \frac{1}{2}mv^2KE=0+21mv2=21mv2

A chemical reaction produces formaldehyde, with a chemical formula of CH2O. Carbon is in Group 4A, oxygen is in Group 6A, and hydrogen is in Group 1A on the periodic table. In one to two sentences, describe the bonds in a molecule of formaldehyde in terms of valence electrons.(2 points)
This problem is providing a comparison on the atoms forming formaldehyde, CH₂O, in terms of the groups they are in, C in group 4A, O in group 6A and H in group 1A, and it is asking for a description about the bonds once they are bonded in a formal Lewis dot structure.
In such a way, the attached file shows the Lewis dot structure, in which we can find two bonds between the two hydrogen atoms and the carbon one, and also, a double bond between carbon and oxygen.
The aforementioned is explained by bearing to mind the concept of octet, which states that elements in groups 4A, 5A, 6A and 7A are able to complete 8 valence electrons after bonding.
Thus, since carbon is in group 4A we infer it needs 4 more electrons to complete the octet, and that is achieved due to the 4 bonds it is having with the two hydrogen atoms and double bond with the oxygen atom.
In addition, since oxygen is in group 6A, we infer it needs two more electrons to complete its octet, which is attained via the double bond it has with the carbon atom. For hydrogen, however, it can complete one bond at maximum, because it is in group 1A, which means it can complete two valence electrons after bonding.

To balance a redox reaction, what must be done?
The ion charge on both sides of the equation must equal zero.
Water must be added to both sides of the equation.
The increase and decrease in oxidation numbers must be balanced.
H+ and OH− must be added to opposite sides of the equation.
To balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.
A redox reaction also called an oxidation- reduction reaction is a chemical reaction in which there is simultaneous gain and loss of electrons.
The species that loses electrons gets oxidized while the species that gains electrons gets reduced. This results in a change of oxidation number. The species that gets reduced decreases in oxidation number and the species that gets oxidized increases in oxidation number.
So, to balance a redox reaction, the simultaneous gain and loss of electrons must be balanced.
Thus, to balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.

What is the molarity of a NaOH solution when 22.14 mL of 0.105 M oxalic acid is needed to
neutralize 25.0 mL of the base.
The molarity of the NaOH solution required for the reaction is 0.186 M
We'll begin by writing the balanced equation for the reaction
H₂C₂O₄ +2NaOH —> Na₂C₂O₄ + 2H₂O
From the balanced equation above,
The mole ratio of the acid, H₂C₂O₄ (nA) = 1
The mole ratio of the base, NaOH (nB) = 2
From the question given above, the following data were obtained:
Volume of the acid, H₂C₂O₄ (Va) = 22.14 mL
Molarity of the acid, H₂C₂O₄ (Ma) = 0.105 M
Volume of the base, NaOH (Vb) = 25 mL
Molarity of the base, NaOH (Mb) =?MaVa / MbVb = nA/nB
(0.105 × 22.14) / (Mb × 25) = 1/2
2.3247 / (Mb × 25) = 1/2
Cross multiply
Mb × 25 = 2.3247 × 2
Mb × 25 = 4.6494
Divide both side by 25
Mb = 4.6494 / 25
Mb = 0.186 MTherefore, the molarity of the base, NaOH solution is 0.186 M
