What are the two kinds of subtances in science?
The two main types of substances in science are elements and compounds. Elements are the simplest form of matter and cannot be broken down further. Compounds are made up of two or more elements chemically bonded together.
Distinction is made between these two kinds of pure substances?
The two kinds of pure substances are elements and compounds. Elements are made of only one type of atom, while compounds are made of two or more types of atoms chemically bonded together in fixed ratios.
What are the 2 kinds of homogeneous matter?
The two kinds of homogeneous matter are solutions and pure substances. Solutions are a mixture of two or more substances that are evenly distributed at a molecular level, while pure substances are composed of only one type of element or compound.
How do the properties of substances formed in chemical changes compare to those of the original substances?
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
The change that takes place when two or more substances interact to form new substances is called a reaction.?
two
What are the two kinds of pure substances?
elements and compounds
What chemical reactions involve two main kinds of changes?
formation of new substances!!

Which type of substances is composed of two or more differant kinds of elements always in the same ratio?
compound
Which type of substances is composed of two or more different kinds of elements always in the same ratio?
compound
What are the two kinds of equilibrium?
The two kinds of equilibrium are the folowing:Physical, which is an open system, and the rate of substances in, equals the rate of substances out.The other equilibrium is chemical equilibrium, which is a closed system, and the rate of the forward reaction equals the rate of the reverse reaction.
What are the 2 kinds of homogeneous matter?
The two kinds of homogeneous matter are solutions and pure substances. Solutions are a mixture of two or more substances that are evenly distributed at a molecular level, while pure substances are composed of only one type of element or compound.
What is the main distinction between the two kinds of pure substances?
The main distinction between the two kinds of pure substances—elements and compounds—lies in their composition. Elements consist of only one type of atom and cannot be broken down into simpler substances by chemical means, while compounds are formed from two or more different types of atoms chemically bonded together and can be broken down into their constituent elements. This difference in composition defines their chemical properties and behaviors.
How do the properties of substances formed in chemical changes compare to those of the original substances?
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
What are two kinds of natural recources found in the Earth?
Two kinds of natural resources found in the Earth are water and minerals. Water is essential for sustaining life and is found in oceans, rivers, and lakes. Minerals are inorganic substances that have economic value and are used for various purposes, such as construction, manufacturing, and energy production.
How do the 2 kinds of pure substances differ?
The particles in a pure substance are all "identical".
