Is reactivity a physical or chemical change?

Is reactivity a physical or chemical change?

Reactivity is surely a chemical property as it is determined by the valence electrons of a substance. Secondly, always a chemical change determines physical change in the substance.

Is reactivity an example of a physical or chemical property?

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust.

What is reactivity with vinegar in science?

Melting Point=Temperature at which a substance goes from solid to liquid. Reactivity with vinegar=Reacts with vinegar to produce new substances.

What type of property is reactivity with vinegar?

8th grade chemistry unit 8

Question	Answer
Reactivity with vinegar	Chemical property- the ability to change the form of the property
elasticity	physical property- the ability to be stretched or not
flammability	Chemical property- the ability to burn
denisity	physical property- the compactness of the substance

What are some examples of reactivity?

Examples of chemical reactivity include mixing substances to make a medicine and the mixture of a toxic spill with substances in the effected environment.

What is the meaning of chemical reactivity?

In chemistry, reactivity is the impetus for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy.

Why is reactivity not a physical property?

Physical properties can be observed or measured without changing the composition of matter. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property.

Is reactivity with water a physical property?

Examples of chemical properties are: heat of combustion, reactivity with water, PH, and electromotive force. The more properties we can identify for a substance, the better we know the nature of that substance.

What is the chemical equation of vinegar?

CH₃COOH
Acetic acid/Formula

Is reacts with vinegar a chemical property?

A chemical reaction is a process in which substances undergo a chemical change to form a different substance. Mixing baking soda and vinegar will create a chemical reaction because one is an acid and the other a base.

How does baking soda and vinegar react with each other?

Baking soda and vinegar react with each other because of an acid -base reaction. Baking soda is a bicarbonate (NaHCO 3) and vinegar is an acetic acid (HCH 3 COO). Is baking soda in vinegar a chemical or physical change?

Is the decomposition of baking soda a chemical change?

Is baking soda and water a chemical change? Baking soda dissolves readily in water . The decomposition of baking soda on heating is a chemical property. You can observe the decomposition of baking soda , but, after you make this observation, you no longer have baking soda . Instead you have carbon dioxide, water , and sodium carbonate.

Is the color of a substance a chemical change?

The changing of color of a substance is not necessarily an indicator of a chemical change . For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction , a color change is usually an indicator that a reaction is occurring. Is toasting bread a chemical change?
