What substances can be separated into simpler substances only by chemical means sodium salt water water water or gold?
Sodium can be separated into simpler substances only by chemical means. Water, salt, and gold are pure substances that cannot be separated into simpler substances by chemical means.
Is the chemical reaction of water with other substances chemical weathering?
yes
What substances can be separated into simpler substances only be chemical means?
Salt water
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
What substances can be separated by chemical means salt water water gold?
salt water
What substances combine without a chemical reaction?
Substances like oil and water can mix without undergoing a chemical reaction, forming a mixture. Similarly, sugar and water can dissolve into each other without a chemical reaction occurring. These are physical changes where the substances retain their original properties.
What is a solution when water is the solvent?
When chemical substances are dissolved in water, this is called an aqueous solution.
Is a reaction with many substances a physical property of water?
No, a reaction with many substances is not a physical property of water. Physical properties of water include its boiling point, density, and color, whereas the ability to undergo reactions with different substances is a chemical property.
What would not be considered a chemical reaction?
A physical change, such as melting ice into water or dissolving sugar in water, would not be considered a chemical reaction because the substances involved retain their original chemical properties. Similarly, phase changes like boiling or freezing do not alter the chemical composition of the substances. In these cases, no new substances are formed, which is a key characteristic of chemical reactions.
Is adding dish soap to water in a sink considered a chemical change?
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
Is reacts with a base to form water a chemical property or a physical property?
it is a chemical property because it changes the chemical structure of the molecules in the base
Is the exploding of potassium metal in water a chemical change?
Yes, the exploding of potassium metal in water is a chemical change. This reaction involves the formation of new substances (potassium hydroxide and hydrogen gas) with different chemical properties than the original substances (potassium metal and water).
