O2 would need to react in 3.1 L of volume.
Given data:-2NO(g) + O2(g) ==> Equation that is balanced: 2NO2(g)
We can observe that 2 moles of NO react with 1 mole of O2 using this equation. We can also state that 2 liters of NO and 1 liter of O2 react under conditions of constant pressure and temperature. The amount of O2 required to react with 4.8 L of NO can then be calculated as follows:
6.2 L NO multiplied by 1 L O2 divided by 2 L NO results in a need for 3.1 L of O2.

i. Define “isotope” using mass number, atomic number, and neutrons
Please please please help and harry
Isotopes have the same atomic number but a different atomic mass. Isotopes of an element carry a different number of neutrons.
What is an isotope?Isotopes can be described as atoms of an element that have the same atomic number but a different mass number. Isotopes of an element contain the same number of electrons and protons as the actual element. but the number of neutrons are different in their respective nucleus.
For example, the isotopes of oxygen element are oxygen-16, oxygen-17, and oxygen-18 they all have 8 electrons or protons. As the number of neutrons in oxygen increases by one, it forms a new isotope of oxygen.
As for the isotope, the number of electrons in the isotope of any element is the same. Therefore, isotopes of any element carry the same atomic number but a different mass number.

A C₁4H₁2
B C₁4H12O4
C C₂H6
D C-H₂O₂ 2
The correct reactant that matches the equation is c)C₇H₆.
The missing reactant for the combustion reaction is C₇H₆. The complete reaction would be
2C₇H₆ + 1502 →14CO2+ 6H₂O.
C7H6 is a hydrocarbon molecule. The name of this molecule is heptendiin
If heptendiin is heated in the presence of oxygen, it will undergo combustion to form carbon dioxide and water vapor. When heptendiin is burned in air, the products of combustion are carbon dioxide and water vapor.
The combustion of this compound is a exothermic reaction, meaning that it releases heat on burning to give out Carbon-di-oxide and Water.
When 2 moles of C₇H₆ reacts with 15 moles of Oxygen, it gives 14 moles of Carbon-di-oxide and 6moles of water molecule.
Therefore the missing reactant, that gives out water and carbon-di-oxide is C₇H₆. Hence, the correct option is c)

What two processes decrease the motion of particles
According to the research, the correct answer is solidification and condensation. These processes that decrease the motion of particles.
What are solidification and condensation?Solidification refers to the state that can be produced by the compression of the matter in question or by a drop in temperature, decreasing the kinetic energy of the particles, favoring the appearance of cohesive forces between them.
In this sense, condensation is the process of transforming a gaseous body into a liquid, by decreasing the temperature, decreasing the energy contained in the gas particles, therefore their motion.
Therefore, we can conclude that solidification and condensation are processes that imply a decrease in temperature and therefore decreases the motion of particles by losing energy.

1. What does Heisenberg's principle of uncertainty state about the position and velocity of an electron
Neither can be measured with any level of certainty at the same time.
Only one can be measured with some level of certainty at a given time.
Both can be measured with a low level of certainty at the same time.
Both can be measured when a high level of certainty at the same time.
Answer:
Both can be measured with a low level of certainty at the same time.
it depends on what you count as low or high levels of uncertainty though.
Explanation:
The equation is something like:
[tex]\Delta x \Delta p \geq \frac{h}{4 \pi}[/tex]
delta x is the uncertainty (not change) of position, and delta p is the uncertainty of momentum. then term on the right is a constant (in this case, a very small number)
This equation tells us that neither the uncertainty of position nor the uncertainty of momentum can be zero, which means that there will always be some uncertainty. However, we can note that both of the uncertainties can be quite small at the same time, they just can't be smaller than h/4pi. This means that both can be measured with a fairly high level of certainty at the same time. However, there is a limit of how high the values can be, so i would expect that the answer your teacher is looking for is that both can be measured with a low level of certainty at the same time. This is always true, as opposed to saying that both can be measured when a high level of certainty at the same time, since high is quite subjective
You have 505 mL of a 0.140 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add?
The volume of water that should be added in the given solution is equal to 202 ml.
What is the dilution law?The concentration or the volume of the dilute or concentrated solution can be calculated from the following equation:
M₁V₁ = M₂V₂
where M₁, V₁, M₂, and V₂ are the concentration and volume of the concentrated solution and dilute solution respectively.
Given, the concentration of the solution, M₁ = 0.14 M
The concentration of the diluted solution, M₂ = 0.100 M
The volume of concentrated solution, V₁ = 505 ml
Put the value of the molarity and volume in equation (1):
(0.140)× (505) = (0.100) × (V₂)
V₂ = 707 ml
The amount of water should be added = 707 - 505 = 202 ml

Using the same sample of gas ( P1 = 735 torr , T1 = 6 ∘C ), we wish to change the pressure to 7350 torr with no accompanying change in volume or amount of gas. What temperature T2 , in Celsius, is needed to reach this pressure?
Express your answer with the appropriate units.
The temperature T₂, in Celsius, that is needed to reach the pressure of 7350 torr is 2517 °C
How do I determine the temperature T₂?From the question given above, the following data were obtained:
Initial pressure (P₁) = 735 torr Initial temperature (T₁) = 6 °C = 6 + 273 = 279 KVolume = ConstantNew pressure (P₂) = 7350 torrNew temperature (T₂) =?Since the volume isconstant, we can determine the new temperature, T₂ as illustrated below:
P₁ / T₁ = P₂ / T₂
735 / 279 = 7350 / T₂
Cross multiply
735 × T₂ = 279 × 7350
Divide both side by 735
T₂ = (279 × 7350) / 735
T₂ = 2790 K
Subtract 273 to obtain answer in °C
T₂ = 2790 – 273 K
T₂ = 2517 °C

how many moles of oxygen are required?
B. How many moles of each product are formed?
Based on the mole ratio of the balanced equation of the reaction,
4.5 moles of ethane will require 15.75 moles of oxygenMoles of carbon (iv) oxide, CO₂, produced is 9 molesMoles of water, H₂O, produced is 13.5 molesWhat is the mole ratio of the reaction?The mole ratio of the reaction is obtained from the balanced equation of the reaction as follows:
Balanced equation of reaction: 2 C₂H₆ + 7 O₂ ------> 4 CO₂ + 6 H₂O
