How does the atomic theory of matter explain the law of conservation of mass and law of constant composition?
Each atom of a particular element has a constant (average) weight, and in chemical reactions, the numbers and types of atoms in the reactants must be the same as the numbers and types of atoms in the products. This explains the law of the conservation of mass. Each molecule of a compound or polyatomic element is composed of a fixed number of one or more particular kinds of atoms; this explains the law of constant composition.
Can the neutral atoms of tow different element have the same number of electron explain?
NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.
What is the smallest part of an element that retains the properties of that element and is composed of one or more atoms?
The smallest part of an element that retains the properties of that element and is composed of one or more atoms is called an atom. Atoms are the fundamental building blocks of matter. Each atom is made up of a nucleus containing positively charged protons and usually neutral neutrons, surrounded by a cloud of negatively charged electrons. The unique arrangement and number of these particles determine the chemical properties of the element.
What is surprising about Mars?
it had life on it before so there must be water
How did the discovery of atoms explain the observation that the mass of the products always equals th mass of the reactants in a reaction?
The discovery of atoms clarified that matter is composed of indivisible particles that cannot be created or destroyed in chemical reactions. This principle underlies the law of conservation of mass, which states that the total mass of reactants must equal the total mass of products. Since atoms are merely rearranged during reactions, the mass remains constant throughout the process, ensuring that the mass of products matches that of the reactants. Thus, understanding atomic structure provided a foundational explanation for this fundamental observation in chemistry.

Must the atoms in a molecule be different?
No, the atoms in a molecule do not need to be all different. Molecules can contain multiple atoms of the same element or different elements bonded together. The arrangement and types of atoms in a molecule determine its properties.
What requirement must be met for two compounds to be isomers?
Two compounds are isomers if they have the same molecular formula but different structural arrangements or connectivity of atoms. This means that the atoms are bonded together in different ways, resulting in unique chemical and physical properties for each compound.
Why must helium be cooled to 4k before it will condense explain the fundamental process?
The single atoms of helium gas are small, and has small surface area. They must be cooled to 4K before their attractive forces cause them to condense.

Is hcl organic?
No, an organic compound must contain carbon and HCl only contains hydrogen and chlorine.
What element must be present for a molecule to be considered an organic molecule?
Carbon must be present in a molecule for it to be considered an organic molecule. Organic compounds are typically composed of carbon atoms bonded to hydrogen, oxygen, nitrogen, sulfur, and other elements.
How many atoms make up one molecule of iron oxide Fe2 03?
Well, iron oxide is a combination of iron(Fe) and oxygen (O). We know Fe(III) has a charge of +3 and oxygen has a charge of -2, so we must balance them. Their LCF is 6, so to balance them, we must have 2 atoms of iron (3x2=6) and 3 atoms of oxygen (-2x3=-6). Therefore we know that there are 2+3 atoms in this molecule, so 6 atoms in the molecule.
What is the diameter from the Sun to the mars?
there is no diameter for a diameter must have a full circle, and Mars has an elliptical orbit.
