Answer:
Glucose
Explanation:
Glucose is a source of energy and it is stored in the body (in the form of glycogen) and it can also dissolve in water.
B) Arrhenius bases
C) Brønsted-Lowry bases
D) Brønsted-Lowry acids
3. Use your knowledge of collision theory to explain the results of your experiments in this laboratory.
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 .
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.
