B) Arrhenius bases
C) Brønsted-Lowry bases
D) Brønsted-Lowry acids

Answers

The correct answer is A. Arrhenius acids, such as HCl(aq), produce hydrogen ions when dissolved in water. According to Arrhenius, acids are compounds or ions that releases hydrogen (H+) ions in its aqueous form.

1.Compare and contrast the rate of solution formation between the three physical forms of salt that were placed in the vial and not agitated with the three forms of salt that were placed in the vial and were agitated.2. On the basis of your results, what is the relationship between the temperature of the solvent and the rate of solution formation?
3. Use your knowledge of collision theory to explain the results of your experiments in this laboratory.

Answers

Thestable form of salt at standard temperature and pressure is solid. If you addwater to salt, it will dissolve. However, there are certain factors that affectthe rate of solution formation of salt. The rate of formation of salt solutionis faster when the vial is agitated than when it is not agitated. By agitatingthe solution, you are increasing the surface area of the salt particles incontact with water.

Answer:

answer for number 2

Explanation:

By increasing the temperature of the solvent, the movement of molecules sped up resulting in the more movement of particles and they bump into each other more vigorously. As a result of that, the particles of the solute break faster and dissolve in the solvent faster .

What chemical change is magnetizing steel

Answers

Magnetizing steel is a physical change, not a chemical change.

Magnetizing steel is a physical change, not a chemical change because it does not change the chemical composition of the steel.

A chemical change is a change in which new substances are formed. This is because the atoms in the original substances are rearranged to form new atoms or molecules. There is no chemical change when magnetizing steel. For example, when iron rusts, it reacts with oxygen to form a new substance called iron oxide.

A physical change is a change in which the form of a substance is changed, but the substanceitself is not changed. For example, when you melt ice, you are changing the form of water from a solid to a liquid, but the water itself is not changed.

When you magnetize steel, you are simply aligning the magnetic domains in the steel. Magnetic domains are regions of a material that have a net magnetic field. When the magnetic domains are aligned, the steel becomes magnetized.

Magnetizing steel does not change the chemical composition of the steel. The steel is still made up of the same atoms, and the atoms are still arranged in the same way. The only difference is that the magnetic domains are aligned, which gives the steel its magnetic properties.

Which element is least likely to undergo a chemical reactionA) lithium
B) carbon
C) flourine
D) neon
and can you give me a explanation with the answer you chose

Answers

The correct option is D.
Elements undergo chemical reactions because they are not stable and they want to become stable, that is they want to attain octet form. To attain octet form, an atom of element must have eight electrons in its outermost shell. Thus, elements undergo various types of chemical bonding in order to have 8 electrons in their outermost shells.
Neon has atomic number of 10 and its electronic configuration is 2,8. This means that, neon already has 8 electrons in its outermost shell and so does not need to form any chemical bond with any other element again, it is already stable. This is why, neon is the least likely to undergo chemical reaction and this is also the reason whey the element is chemically inert.
The other elements given in the option do not have 8 electrons in their outermost shell, so they will be quite willing to undergo chemical reactions in order to become stable.
d neon is the element that is least likely to undergo a chemical reaction

A gas occupies 900.0 mL at a temperature of 27.0 . What is the volume at 132.0 °C?

Answers

V₁ = 900.0 mL

T₁ = 27.0ºC + 273 = 300 K

V₂ = ?

T₂ = 132.0 + 273 = 405 K

V₁ / T₁ = V₂ / T₂

900.0 / 300 = V₂ / 405

300 x V₂ = 405 x 900.0

300 x V₂ = 364500

V₂ = 364500 / 300

V₂ = 1215 mL

hope this helps!
