The unstable arrangement of atoms that forms momentarily at the peak of the activation-energy barrier is known as the what?

Answers

The unstable arrangement of atoms that forms at the peak of the activation energy is called the transition state. If I remember correctly It is the point in which all the atoms or molecules (involved in the reaction) collide in the correct orientation to brake the bonds of the reactants and form the bonds in the products.

I hope this helps. Let me know if anything is unclear.

activated complex.

Changing the pressure of a system has the highest effect on a substance in which phase?a. gas
b. solid
c. liquid
d. plasma

Answers

The best answer to the question presented above would be letter a. Changing the pressure of a system has the highest effect on a gaseous phase. Solids and liquids under pressure make little difference, while gas molecules have many behaviors due to change in pressure.

Why does it make sense that if an atom loses electrons, it is left with a pisitive charage?

Answers

Because atoms are neutral. By neutral, I mean that; there are three main particles that make up an atom. Protons, Electrons and Neutrons. Protons have (electrically) positive charge, electrons have negative and neutrons are electrically neutral. One proton's charge is +1 and one electron's charge is -1. An atom (normally) has the same amount of protons and electrons. Let's say if an atom has two protons and two electrons, the sum of electrical charges of the protons is (two times +1) +2 and sum of electrical charge of electrons is (two times -1) -2 . The total charge of the atom is the sum these. So, (-2)+(2)= 0. That makes the charge of the atom 0, thus makes it neutral. But let's say this atom loses one of its electrons, and now has only one. So one electron (-1) and two protons (+2) in total will be : (-1)+(2) = +1 . +1 is positive, so this makes the charge of the atom positive.

Electrons have a net negative charge, therefore by losing them the atom will become slightly more positive.

How many chlorine molecules are in 35.5g of chlorine gas

Answers

since chlorine is one of the 7 diatomic elements we know that chlorine appears as Cl₂ gas naturally. That means that the molar mass of a chlorine gas is 70.9g/mol. That being said, first you need to find the number of moles of chlorine gas that are present in a 35.5g sample. To do this divide 35.5g by the molar mass of chlorine gas (70.9g/mol) to get 0.501mol of chlorine. Then you have to multiply 0.501mol by 6.02×10²³ to get the number of chlorine gas molecules. Therefore 3.01×10²³ molecules of chlorine gas are present in a 35.5g sample.

I hope that helps. Let me know in the comments if anything is unclear.

Which of the following does NOT correctly describe the kinetic molecular theory? Collisions between gas particles are inelastic.Gas particles are small and spherical with an insignificant volume.
During collisions between two gas particles, kinetic energy is transferred without any loss.
The motion of gas particles is constant and random.

Answers

Answer: Collisions between gas particles are inelastic.

Explanation: Kinetic Molecular Theory explains the basic relation between the temperature and the speed of the gaseous molecule . From this theory itself, ideal gas equation was born.

the incorrect postulates among the given is that the 'Collisions between gas particles are inelastic' because during collision, the gas molecules collide with one another as well as with the walls of the container .

Thus there is no loss of kinetic energy in the collision phenomenon .

It is also correctly given that Gas particles are small and spherical with an insignificant volume and the motion of gas particles is constant and random.

Collisions between gas particles are inelastic. - A

The collisions in a gas are assumed to be perfectly elastic

Which statement describes a chemical property of the element magnesium?(1) Magnesium is malleable.
(2) Magnesium conducts electricity.
(3) Magnesium reacts with an acid.
(4) Magnesium has a high boiling point.

Answers

Answer: option 3) magnesioum reacts with an acid.

Justification:

1) Malleability, conduction of electricity, and boiling point are physical properties.

2) Maleability is the ability to be transformed into foil. It is just a change in form. So, it is a physical property.

3) The metals conduct electricity in virtue of the array of the atoms, which permtis the flow of the electrons, but it does not involve a chemical change, so it remains being a physical proerty.

4) Boling point is the temperature at which a substance passes from liquid state to gas state, which are just different forms of the same substance. So, it is other physical property.

5) Reaction with an acid is indeed a chemical transformation: the metal (magnessium) will form a chemical bond with some spieces of the acid to form a new compound. This is a chemical reaction in virtue of the chemcial properties of the substance (its ability to react with acids)

Magnesium reacts with an acid.
