What is the chemical substance formed in the anaerobic respiration in muscles?
Lactic acid is the chemical substance formed during anaerobic respiration in muscles when there is not enough oxygen available to meet energy demands.
Why is knowing the melting point of a substance not enough information to identify the substance?
Because you need to know that it is absolutely pure if you are to rely absolutely on its M.P. Alloys have a wide range of MPs, depending on the exact composition. If you can be sure that your sample is pure lead then you have already identified it !
Why would it probably be difficult to determine the chemical and physical properties of a newly discovered synthetic element?
Any newly discovered synthetic elements are extremely radioactive and have extremely short half-lives and only a few atoms at most can be produced. At the moment, science is not able to isolate enough for a long enough time. Therefore, it would be difficult to collect and keep enough of the element to determine its chemical and physical properties.
How does a chemical change in matter form a new substance?
Chemical bonds in the starting substances must break. molecules are always moving. if the molecules bump into each other with a enough energy, the chemical bonds in the molecules can break. the atoms then rearrange, and new bonds form to make new substances.
Which substance has a chemical composition similar enough to dopamine to allow it to fit the dopamine receptor sites in the brain?
L-dopa is a substance with a chemical composition similar to dopamine that can bind to dopamine receptor sites in the brain. It is commonly used in the treatment of Parkinson's disease to increase dopamine levels.
What is combustion burning?
Combustion or burning is the chemical reaction of a substance in the presence of oxygen. This can be understood with a simple example. Fire is not enough to burn a paper, it also require oxygen in air. During burning or combustion, heat energy is generated and physical and chemical properties of substance are changed.
Is the ability to react with other substances a physical property or a chemical property?
The ability to react with other substances is a chemical property because it describes how a substance interacts with other materials to form new substances with different properties. It is related to the substance's chemical composition and behavior in chemical reactions.
Which 4 specific properties cannot be used to identify a substance?
Color, odor, taste, and state of matter are not specific enough to uniquely identify a substance, as multiple substances may share these properties.
What is the chemical substance formed in the anaerobic respiration in muscles?
Lactic acid is the chemical substance formed during anaerobic respiration in muscles when there is not enough oxygen available to meet energy demands.
Even if you change the shape and amount of a substance it's stays the same?
This statement is incorrect. Changing the shape or amount of a substance can alter its physical and chemical properties. For example, breaking a substance into smaller pieces can increase its surface area and affect its reactivity, while changing the amount of a substance can change its concentration and impact its behavior in a reaction.
Why is knowing the melting point of a substance not enough information to identify the substance?
Because you need to know that it is absolutely pure if you are to rely absolutely on its M.P. Alloys have a wide range of MPs, depending on the exact composition. If you can be sure that your sample is pure lead then you have already identified it !
How can we obtain pure substances from a mixture?
A pure substance is a sample of matter, either an element or a compound, that consists of only one component with definite physical and chemical properties and a definite composition.Here's an example: Grape juice is a mixture, but not a pure substance because if you leave it out long enough, it will begin to separate. If you can think of a mixture that has the qualities of that definition, then answer is yes. If you were think about juice, the answer is no. Hope that helps!
