The unifying relationship among the variables temperature, volume, pressure, and the number of moles is described and summarized by the ideal gas law.
The equation for ideal gas law is given below where T is temperature, V is the volume, P is the pressure, n is the number of moles of the gas, and R is the gas constant 0.082056 L⋅atm/mol⋅K
PV = nRT
Calculate first the moles of O2 from the moles of Ag2O
moles O2 = 0.5 moles Ag2O x 1 mol O2/2 mol Ag2O = 0.25 moles
Assuming that the oxygen gas is an ideal gas, we will use the ideal gas equation to calculate the volume it occupies.
V = nRT/P
V = 0.25 moles*0.082056*546k/1 atm =
11 L
Hence, volume of pure oxygen gas (o2) is 11 L

The dividend paid by Chevron foe 9 months of 2013 is $ 5572 millions.
Calculation:
No. Of outstanding shares = 1,921,429,000
Dividend per share = $2.9
Dividend paid = No. of outstanding shares * dividend per share
= 1,921,429,000 * 2.9
= $5,572,144,100
A dividend is a payment made to shareholders in exchange for their investment in a company's equity, and it is usually derived from the company's net profits. When a cash dividend is paid, the funds are transferred to a liability account known as dividends payable.
When the company makes the payment on the dividend payment date, which is usually a few weeks after the ex-dividend date, this liability is removed. Cash dividends and tick dividends have no effect on a company's net income or profit.

According to newton's second law, if you double the force acting on a body, the acceleration will double.
a. true
b. false
It is the true statement, that if we double the force acting on a body, the acceleration will double.
What is acceleration?In terms of both speed and direction, acceleration is the rate at which velocity varies over time. Acceleration refers to the change in speed or direction of an item or point travelling straight forward. Due to the constant change in direction, motion on a circle accelerates even while the speed is constant. Both impacts help to accelerate all other types of motion.
In order to be a vector quantity, acceleration must have both a magnitude and a direction. As a vector quantity, velocity is also. A time interval's velocity vector change divided by that interval's duration is the definition of acceleration.

BCC unit in a cell : It consists of 8 atoms on vertices and 1 atom at the centre.
Therefore, side length = 0.282 nm
1. No of atoms in the BCC cell = 1 / 8 *8 + 1 = 2 atoms
Atomic atoms = No of atoms * weight
= 2 * 48.9 g/mol = 97. 8 g / mol;
Mass of one mole = Atomic weight / No of mole
= 97.8 /6.022 * 10²³
= 16. 24 * 10⁻²³ g
Density = mass / volume
7.24 = 16. 24 * 10⁻²³ / a³
a = 2.82 * 10⁻⁸ cm ⇒ Side length
Relation between side length and the radius of atom is
a = 4R / √3

Did helium created in fusion in the solar core reach the solar surface? explain.
The fusion of hydrogen nuclei in stars produced all of the helium in the Universe.
However, most stars undergo an internal transformation after turning a considerable percentage of their hydrogen to helium. The interior core compresses and warms up until it is hot enough to fuse helium into bigger atoms, for as by fusing three helium atoms into carbon. At the same time, some helium will combine with the carbon to generate oxygen. Outside the core, in what is known as the envelope, there is still enough hydrogen to fuse into additional helium. However, the center starts fusing heavier nuclei. This, by the way, is the transition from a 'regular' star like our Sun to a Red Giant.
After the red giant phase, the Sun will shed its outer layers, leaving behind a helium-rich core that will gradually cool throughout the course of the Universe. After the red giant phase with stars more massive than the Sun, it becomes practically a free for all for producing heavier and heavier atoms. When the helium in the core runs out, the star collapses again, heats up, and begins fusing carbon and oxygen into bigger atoms. If the star is large enough, this will continue until iron is fused. At such time, a hotter core will still not result in fusion. The star falls, becomes unstable, and explodes, resulting in supernovae and neutron stars (or black hole).

A father and his young daughter are ice skating. According to it, the daughter has greater speed.
The law of action and response is Newton’s third principle.According to Newton’s third law, when two bodies come into contact, they exert forces on one another that are equal in size and directed in the opposite direction. The law of action and reaction is another name for the third law.
This law applies to bodies in uniform or rapid motion and is crucial for addressing problems of static equilibrium, where all forces are in balance. The forces it discusses are actual phenomena, not just accounting tricks.
If there is a net force operating on a body, it moves faster in line with the second rule.
If there is no net force acting on the body, either because there are no forces at all or because all forces are precisely balanced by opposing forces, the body does not accelerate and is said to be in equilibrium.
On the other hand, it can be assumed that a body that appears to be moving slowly has no net force acting on it.

explain the statement, the acceleration of free fall due to gravity on the Earth's equator is 9.78m/s²
This means that at the equator, the force of gravity on a body causes its velocity to increase at the rate of 9.78m/s per second because of acceleration of free fall cohesion.
What is acceleration of free fall cohesion?An object that is falling freely is one that is only being affected by gravity. A free-falling object experiences a downward acceleration of 9.8 m/s/s (on Earth). This specific name is given to the numerical value for an object in free fall because it is such an essential value. The acceleration of any object moving solely as a result of gravity is referred to as the "acceleration of gravity."

The average velocity of you and your family go from Charleston to New Orleans is (Vₐ)= 152.92 km/h
What is velocity?The term velocity explains that the object or particle displacement within the respected time. Average velocity is total displacement divided by total time.
How can we calculate the value of average velocity?To calculate the value of average velocity we are using the formula here is,
Vₐ = (s₁+s₂)/(t₁+t₂)= sₐ/tₐ
Here we are known,
t₁= You and your family leave to go from Charleston to New Orleans = 7:00 am.
t₂=You and your family reached to go from Charleston to New Orleans = 4.00 pm.
tₐ=Time interval between the leaving and reaching time=9 hour.
sₐ= The trip’s distance to go from Charleston to New Orleans= 850 miles
Now we put the values in the above equation we get,
Vₐ =sₐ/tₐ
Or, Vₐ =850 miles/9 hour
Or, Vₐ =94.4 miles/hour.
Or, Vₐ = 152.92 km/hour.

What is a friction?The force preventing solid surfaces, fluid layers, and sliding material components from moving in the same direction is known as friction. Friction between two surfaces causes kinetic energy to be converted into thermal energy when they move in relation to one another (that is, it converts work to heat). The utilization of friction produced by rubbing pieces of wood together to start a fire serves as an example of how this attribute can have dramatic effects.

Find the prime factorization of the integers of the form 10p-1 for p=1-7 what is the relevance of these factorizations to the behavior to the behavior of the decimal representation?
The integers can be arranged in the form of 10p - 1 such that p = 1-7 in the was as follows:
10p-1 = (10*1) - 1 = 9 = [tex]3^{2}[/tex] = 3x3
10p-1 = (10*2) - 1 = 19 = [tex]19^{1}[/tex]
10p-1 = (10*3) - 1 = 29 = [tex]29^{1}[/tex]
10p-1 = (10*4) - 1 = 39 = 3x13
10p-1 = (10*5) - 1 = 49 = [tex]7^{2}[/tex] = 7x7
10p-1 = (10*6) - 1 = 59 = [tex]59^{1}[/tex]
10p-1 = (10*7) - 1 = 69 = 3x23
Here we see that not all are in the form of 2^n x 5^m where n and m are non-negative integers.
As per the rule, if A =p/q be a rational number such that p and q are co-prime and the prime factorization of q is not in the form of 2^n x 5^m where n and m are non-negative integers, then A has a decimal expansion which is non-terminating recurring decimal.
