What else can I help you with?
Which pair is classified as chemical substances?
Water and salt are classified as chemical substances. Water is made up of hydrogen and oxygen molecules, while salt is made up of sodium and chloride ions. Both substances undergo chemical reactions to form new compounds.
Is plastic made out of rocks or is plastic made out of minerals?
no, plastic is made out of oils usually petroleum.
What energy is made in the reactions of cellular respiration?
Chemical Energy
Which kind of chemical reaction has compounds that split apart to from smaller compounds?
Decomposition reactions involve a compound breaking down into two or more smaller compounds. This is usually caused by the introduction of some form of energy such as light which breaks bonds between atoms. However, combustion reactions can also involve compounds splitting into simpler ones. A combustion reaction involves a compound made up of carbon, hydrogen, and occasionally oxygen atoms reacting with oxygen gas, O2, to form water and carbon dioxide. However, the answer to your question is probably decomposition reactions.
Which part of cement is chemical?
Cement, as with all substances, is entirely made of chemical compounds made of chemical elements. From the wording of your question it is not possible to give you a clearer answer as what you are asking is not clear.
What is the relationship between the molecules of elements and compounds in chemical reactions?
In chemical reactions, molecules of elements and compounds interact and rearrange to form new compounds. Elements are made up of single types of atoms, while compounds are made up of different types of atoms bonded together. During a chemical reaction, the bonds between atoms in molecules are broken and new bonds are formed, resulting in the creation of different compounds.
What are made during chemical reactions?
the result that comes by mixing the chemical to chemical
What is formed by the combining of elements or other compounds through chemical reactions?
A compound is formed by the combining of elements or other compounds through chemical reactions. Compounds are made up of molecules that contain two or more different elements chemically bonded together in a fixed ratio. These chemical bonds are formed by the sharing or transfer of electrons between atoms.
What type of products are made in chemical reactions involving the shifting of atoms of one molecule to another?
Compounds
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What compounds are typically made in a laboratory setting?
Compounds typically made in a laboratory setting include pharmaceuticals, chemicals, polymers, and materials for various industries. These compounds are synthesized through chemical reactions and processes under controlled conditions.
How do elements relate to compounds?
Chemical compounds are formed from chemical elements.
Which pair is classified as chemical substances?
Water and salt are classified as chemical substances. Water is made up of hydrogen and oxygen molecules, while salt is made up of sodium and chloride ions. Both substances undergo chemical reactions to form new compounds.
Can compounds be further divided?
Compounds are made up of two or more elements that are chemically bonded together. Compounds can be broken down into simpler substances through chemical reactions, but once broken down, they lose their compound properties. In summary, compounds can be divided through chemical reactions, but the resulting substances are not considered compounds.
How do elements differ from the compounds they form?
Elements are pure substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms chemically bonded together. Elements cannot be broken down into simpler substances by chemical reactions, whereas compounds can be broken down into their constituent elements through chemical reactions. Elements are the building blocks of compounds.
How do you indentify compounds?
Identification of compounds is made by chemical analysis.
How are compounds and formulas related?
All chemical compounds will have a chemical formula. For instance, the calcium chloride has formula CaCl2. Elements, on the other hand, have chemical symbols. Chemical reactions can be represented by chemical equations.
