Can acids donate an electron pair?
No, acids cannot donate an electron pair. Acids are substances that tend to donate a proton (H+) in a chemical reaction, while bases are substances that can donate an electron pair.
Because carbon cannot be decomposed by simple chemical methods into two or more different substances what is it classified as?
Carbon is classified as an element because it consists of only one type of atom, which cannot be decomposed into simpler substances using chemical methods.
Why are the substances on the periodic table classified as elements?
Substances on the periodic table are classified as elements because they are pure substances made up of only one type of atom. Each element has a unique chemical structure and properties that distinguish it from other elements.
Why is water not classified as a mixture?
Water is not classified as a mixture because it is a pure substance with a definite chemical composition (H2O). A mixture, on the other hand, consists of two or more substances physically combined with no fixed composition.
What can pure substances be classified as?
Pure substances are divided into elements and compounds.
Different substances can be classified by their chemical properties or properties that?
Different substances can be classified by their physical properties, such as color, density, melting point, and boiling point. Chemical properties, on the other hand, refer to the behavior of a substance in reactions with other substances, such as its reactivity, flammability, and toxicity.
Minerals are classified by-?
Minerals are substances that naturally occur. This is solid that has a chemical formula.
Substances such as NaOH which dissociate into OH- ions are classified as?
Substances that dissociate into hydroxide (OH-) ions are classified as bases. These bases are capable of accepting protons (H+) in chemical reactions.
Can acids donate an electron pair?
No, acids cannot donate an electron pair. Acids are substances that tend to donate a proton (H+) in a chemical reaction, while bases are substances that can donate an electron pair.
Because carbon cannot be decomposed by simple chemical methods into two or more different substances what is it classified as?
Carbon is classified as an element because it consists of only one type of atom, which cannot be decomposed into simpler substances using chemical methods.
What lists the properties by which substances are classified in chemistry?
The groups on the periodic table help you recognize chemical properties of a substance.
Hydrogen and chlorine are pure substances of what?
Hydrogen and chlorine are chemical elements, not compounds
Why are the substances on the periodic table classified as elements?
Substances on the periodic table are classified as elements because they are pure substances made up of only one type of atom. Each element has a unique chemical structure and properties that distinguish it from other elements.
Why are burning wood and metal rusting classified as chemical change?
Both result in "new" substances (ash, smoke, rust).
What are the properties of the substances?
Properties of substances refer to their characteristics that can be observed or measured, such as color, density, solubility, melting point, boiling point, and chemical reactivity. These properties are used to identify and differentiate between different substances. Additionally, properties can be classified into physical (observable without changing the substance's identity) and chemical (characteristic behaviors in chemical reactions).
Why is water not classified as a mixture?
Water is not classified as a mixture because it is a pure substance with a definite chemical composition (H2O). A mixture, on the other hand, consists of two or more substances physically combined with no fixed composition.
What is changes of chemistry?
Changes in chemistry refer to alterations in the properties and composition of substances as a result of chemical reactions. These changes can be classified as physical changes, where the substance's form is altered without changing its composition, or chemical changes, where new substances are formed. Understanding these changes is fundamental to understanding the behavior of matter in various environments.
