A sample of gas in a closed container at a temperature of 76°c and a pressure of 5. 0 atm is heated to 399°c. What pressure does the gas exert at the higher temperature? report your answer in atmospheres to one decimal place.
By using ideal gas approximation, the final pressure is 9.6 atm.
We need to know about ideal gas to solve this problem. The ideal gas will follow the rule
P . V = n . R . T
where P is pressure, V is volume, n is the amount of substance, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.
In the isochoric process where the initial and final volume is the same, the temperature and pressure will follow the rule
P1/T1 = P2/T2
where P1 is initial pressure, P2 is final pressure, T1 is initial temperature and T2 is final temperature. (Temperature in Kelvin)
From the question above, we know that:
P1 = 5.0 atm
T1 = 76°C = 349 K
T2 = 399°C = 672 K
By substituting the parameters, we get
P1/T1 = P2/T2

In ppm the concentration of NH2- ions is 5.6 ppm.
We have 1 L sample of water contains 0.0056 g of NH2- ions.
We have to determine the concentration of NH2- ions in ppm.
What is PPM ?PPM is a term used in chemistry to denote a very, very low concentration of a solution.
According to the question -
Mass of the aqueous solution of NH2- ions → density x volume →
1 L x 1000 mL x 1 g/mL = 1000g
Now, the ratio of chloride ion mass to the solution mass will give the concentration of NH2- ions →
c = 0.0056/1000
Now, in order to express the concentration in parts per million -
c = (0.0056/0.001 x 10⁶) = 5.6/10⁶
Now -
c = 5.6 g of NH2- ions per 1 million grams of solution which is equal to concentration in ppm.
Hence, in ppm the concentration of NH2- ions is 5.6 ppm.

What is an electrical insulator?Electric current cannot readily travel through an electrical. Due to their closely bonded state, the insulator's atoms' electrons are immobile. Electric current can flow through other materials more easily, such as semiconductors and conductors. Insulators have higher resistivities than semiconductors or conductors, which makes them stand out from other materials. Non-metallic are the most typical examples.
Since even insulators contain minute amounts of mobile charges (charge carriers) that can carry current, a perfect insulator does not exist. A sufficiently high voltage is supplied to cause the electric field to pull electrons from atoms, which causes all insulators to turn electrically conductive. An insulator's breakdown voltage is what this is.

If you exert a force f on an object which has a much greater mass than you do, the force which the object exerts on you will?
If you exert force on an inanimate item, you will also be able to calculate the force that the object will apply to you, which will be opposing and equal to your own.
What would happen if you applied a force that was smaller than the object's mass?In order to accelerate a heavier (more massive) item in motion, more force must be exerted. When two objects are subjected to the same force, the smaller mass item will change speeds more quickly.
An item can alter its size or shape, begin moving, stop moving, accelerate, or decelerate as a result of a force acting on it. When two things contact, they exert pressures on one another that are identical in size but directed in the opposite direction
The action-reaction law is another name for this rule.

Between the liquid plasma and the platelets that are tracked into a small pouch that is wrapped around the centrifuge cylinder as the liquid plasma rises. When you donate blood, your spleen releases stockpiled platelets into your bloodstream in an effort to stop the bleeding.
As a result, more platelets and plasma are collected, enabling you to donate one, two, or even three doses of platelets in a single visit. Your healthy bone marrow quickly starts producing additional platelets from stem cells to replace those that have been given while this is happening.

The function s(t) represents the position of an object. suppose s(2) = 125 and s(4) = 175. find the average velovity of the object over the interval of time [2,4]
The average velocity of the object = 25m/s
CalculationIt is given that s (2) = 125
s (4) = 175
and we have to find average velocity of the object over the interval of time [2,4]
Using two-point formula, we have
[tex]\frac{s-125}{175-125}[/tex] = [tex]\frac{t-2}{4-2}[/tex]
s = 25t -50 + 125
s = 25t + 75 gives the position of t

Mixtures are the combination of substances ?A mixture could be homogeneous or heterogeneous.
A mixture refers to a combination of two or more substances that are not chemically combined together. They may be solids, liquids or gases.
A mixture may be composed of substances in the same phase or different phases. If substances are combined in the same phase to form a mixture then the mixture is homogeneous. If substances in different phases combine to give a mixture then the mixture is heterogeneous.
Examples of homogeneous mixtures are salt and water solutions while examples of heterogeneous mixtures are sand and water as well as oil and water.
