What else can I help you with?
Is does not react with cold water is a physical property?
A reaction with water (hot or cold) is a chemical reaction.
Is Reacts in water is a chemical property?
Yes, the reaction of a substance with water is considered a chemical property. It involves a chemical change where new substances are formed due to the rearrangement of atoms in the reactants. This is different from a physical property, which does not involve a change in the chemical composition of the substance.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
Is cornstarch mixed with water a chemical reaction?
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
What is the difference between physical property and chemical property?
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.
Is does not react with cold water is a physical property?
A reaction with water (hot or cold) is a chemical reaction.
Why is the changes of color when mixed with water a physical property?
The change of color when a substance is mixed with water is a physical property because it does not alter the chemical composition of the substances involved. It is merely a change in appearance due to the interaction of light with the new mixture. This change can be reversed by separating the substances.
Is combustion a physical or chemical property?
Combustion is a chemical property, as it involves a chemical reaction between a fuel and oxygen to produce heat, light, and new substances like carbon dioxide and water vapor.
Is Reacts in water is a chemical property?
Yes, the reaction of a substance with water is considered a chemical property. It involves a chemical change where new substances are formed due to the rearrangement of atoms in the reactants. This is different from a physical property, which does not involve a change in the chemical composition of the substance.
Krypton gas floats above air is it a chemical or physical?
It is a physical property. Any gas that has a lower density than air will float above air. This is similar to how if you pour oil into water. The oil will float on the water because it is less dense.
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.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
When water boils at 100c is that example of chemical property?
No, boiling point is a physical property of a substance, not a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances.
When sodium reacts violently with water is it physical or chemical property?
The reaction of sodium with water is a chemical property because it involves a chemical change where new substances are formed (sodium hydroxide and hydrogen gas) with different properties compared to the original substances (sodium and water). Physical properties, on the other hand, are characteristics of a substance that can be observed without changing its chemical composition.
Is sodium metal exploding in water a physical property?
No, sodium metal exploding in water is a chemical reaction, not a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's composition, such as color, density, or melting point.
Is cornstarch mixed with water a chemical reaction?
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
