The average kinetic energy of a distribution of free non-interacting particles is related to the absolute temperature.Thus the absolute temperature is a measure of the average kinetic energy of the population.

WHAT IS KINETIC ENERGY


kinetic energy is an expression of the fact that a moving object can do work on anything it hits, it quantifies the amount of work the object could do as a result of its motion.

Would changing the atoms in water would it separate from what is attached.


Changing the atoms how? It takes a lot of energy to do that, and afterward it is not water anymore but some other substance, oxygen and hydrogen.

You can change the arrangement of molecules in water, when you freeze or evaporate it though

What is energy ?


Put simply, it is a capacity to do work, which in turn is the moving of something over a distance. So your muscles can generate energy by burning metabolites and pedalling a bicycle.

That is a bit oversimplified though when you consider the different kinds of energy. There is

- potential energy, possessed by something, which can be released. The most obvious example is an elevated object which can fall.

- kinetic energy, such as a speeding car which can knock down a pole

- electric energy, a combination of voltage and current

- nuclear energy, bound up in the atom

and others too

How many atoms of hyrdrogen gas in tow moles how


Hydrogen gas is a diatomic substance: Each molecule contains two hydrogen atoms.
A mole of hydrogen gas contains 6.02*10^23 hydrogen molecules, but since each molecule contains 2 hydrogen atom you have 2*6.02*10^23=?
The formula for nitric acid is HNO_3. It contains 5 atoms regardless of the elements
Now, 0.25 moles contain 0.25* 6.02*10^23 molecules oh nitric acid, ans since each molecule contains 5 atoms then 0.25 moles contain 0.25*5*6.02*10^23=? atoms
0.25*1*6.02*10^23 of hydrogen atoms, and the same number of nitrogen atoms and 0.25*3*6.02*10^23 oxygen atoms.

How many grams of aluminum acetate contain 2.24 x 1022 atoms of hydrogen?


1 Look up the formula for the aluminum acetate.
2 Count the number of Hydrogen atoms per molecule: Call that nH.
3 Dividing 2.24*10^22 by nH you get the number of molecules of acetate.
4. Divide that number by Avogadro's Number to obtain the number of moles required.
5. Multiply the number of moles by the molecular mass of the aluminum acetate (look it up or use the periodic table to calculate it), you will get the mass of aluminum acetate that contains 2.24*10^22 hydrogen atoms.

What is matter?


Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.
The most familiar examples of material particles are the electron, the proton and the neutron. Combinations of these particles form atoms. There are more than 100 different kinds of atoms, each kind constituting a unique chemical element. A combination of atoms forms a molecule. Atoms and/or molecules can join together to form a compound.
Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas. A single element or compound of matter might exist in more than one of the three states, depending on the temperature and pressure. Less familiar states of matter include plasma, foam and Bose-Einstein condensate. These states occur under special conditions.
Different kinds of matter can combine to form substances that may not resemble any of the original ingredients. For example, hydrogen (a gaseous element) and oxygen (another gaseous element) combine to form water (a liquid compound at room temperature). The process of such combination is called a chemical reaction. A chemical reaction involves interactions between the electrons of the atoms, but does not affect the nuclei of the atoms.


I hope you find it very helpful. Best regards.

Ionization


Please restate as a question. Do you mean "what is ionisation?" If so: ionisation is the physical process of converting a molecule or atom into an ion by adding or removing charged particles such as electrons or other ions, to form a charged form of the atom or molecule.

How do I calculate this question with the fx-115es. Find the number of moles of nitrogen in 1.75 mol N2H4?


You have 1.75 moles of hydrazine or 1.75xNa molecules of the substance. Since each molecule of N2H4 contains 2 atoms of nitrogen 1.75Na molecules contain 2x1.75xNa atoms of nitrogen. The number of moles of nitrogen is 2x1.75xNa/Na, which leaves 2x1.75 or 3.5 moles.
Your answer: 1.75 mol of hydrazine contain 3.5 mol of nitrogen atoms.
