Question7. gas is a(n) compound, element, homogeneous mixture, or heterogeneous mixture?
Studdy Solution
STEP 1
Assumptions1. gas is a molecule made up of two chlorine atoms. . We need to classify gas as either a homogeneous mixture, a heterogeneous mixture, a compound, or an element.
STEP 2
We need to understand the definitions of the four options.
1. A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture.
2. A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties.
. A compound is a substance formed when two or more chemical elements are chemically bonded together.
4. An element is a substance whose atoms all have the same number of protons.
STEP 3
We need to apply these definitions to gas.
1. gas is not a mixture, as it is composed of only one type of atom, chlorine. Therefore, it cannot be a homogeneous or heterogeneous mixture.
2. gas is not a compound, as it is not formed by chemically bonding two or more different elements together. It is formed by two atoms of the same element, chlorine.
3. gas is an element, as it is a substance composed of atoms all having the same number of protons.
STEP 4
Therefore, gas is an element.
