the sand, salt, and water from each other?
(1) Evaporate the water, then filter out the salt.
(2) Evaporate the water, then filter out the sand.
(3) Filter out the salt, then evaporate the water.
(4) Filter out the sand, then evaporate the water.
Answer is (4).
Explanation:
The given mixture contains an insoluble solid and an aqueous solution of salt. The insoluble solid is sand.
First we have to separate insoluble solid. Sand can be separated by doing filtration. When we filter the mixture sand can be seen as the residue on the filter paper.
After filtering the mixture, we should collect the filtrate. Filtrate is the salt solution. By doing evaporation we can get the solid salt.
First and second choices are wrong because after evaporating water filtrationcannot be done and salt and sand will be mixed together.
Salt cannot befiltered out because the salt is soluble and it is inaqueous medium. Hence, third choice is wrong

John Dalton contribute to the understanding of the atom that all matter was composed of atoms, indivisible and indestructible building blocks.
While all atoms of an element were identical, different elements had atoms of differing sizes and mass.
An atom is a particle of matter that uniquely defines a chemical element.
An atom consists of a central nucleus that is usually surrounded by one or more electrons.
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The theory states that all matter is made of atoms, which are indivisible.
(1) All matter is composed of tiny, indivisible particles, called atoms, that cannot be destroyed or created.
(2) Each element has atoms that are identical to each other in all of their properties.

Answer:
Exothermic reaction
Explanation:
Notice that the energy component is located on the right side of the reaction. The right side is always known as the product side. Whenever energy is located there, the reaction is known to give off energy - essentially, we can say that energy is a product, as well. Reactions that give off energy are known as exothermic reactions.
On the other hand, if the energy component was located on the left side, or reactant side, of the equation, it would be known as an endothermic reaction.
Here, it's exothermic.
