What is formed when two substances combine and form a new substances combine and form a new substance which cannot return to their original form?
a chemical reaction
What is formed when two or more substances come together but don't combine to from a new substances?
Mixture
Is a new substance formed by a chemical reaction between two substances a compound or a mixture?
Yes, they can mixed together
When two substances combine chemically the properties of the products of what?
When two substances combine chemically, the properties of the products are different from those of the starting materials. This is because new chemical bonds are formed, leading to a different arrangement of atoms and different chemical properties.
When atoms combine is it a physical change or a chemical change?
When atoms combine to form molecules, it is a chemical change. In a chemical change, new substances are formed with different properties from the original substances. This is in contrast to physical changes, where the state or appearance of a substance may change without forming new substances.
How mixture and substance are similar?
Mixtures are formed from substances (compounds).
What is most matter on the earth made of is it compoundelementssolution?
Most matter on Earth is made up of elements. Elements are substances that cannot be broken down into simpler substances by chemical means. Compounds are formed when different elements chemically combine together. Solutions are homogeneous mixtures where one substance is dissolved in another.
A substance formed when atoms of different elements combine?
A compound.
What is the new substance formed when elements combine chemically?
compound
When two elements combine to form a new substance is the new substance an element Why and why not?
No, the new substance formed when two elements combine is not an element. Elements are substances made of only one type of atom, while compounds are made of two or more different types of atoms chemically combined. The new substance formed from the combination of two elements is a compound, not an element.
When two substances are combined and new substances are formed?
When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
What is a substance formed when ions combine?
An ionic compound is formed when ions combine. These compounds are made up of positively charged ions (cations) and negatively charged ions (anions), which are held together by strong electrostatic forces.
