What is meant of '. ' in chemical reaction?
'.' shows the multiplication in chemical reaction.
What is the relationship between a Chemical reaction and a chemical equation?
The chemical equation demonstrates the ratio of chemicals reacting and producing. Even though only minute amount of actual chemicals are reacting, the chemical equation shows which chemicals are doing what.
What kind of reaction shows two reactants combining to form one new profuct?
combination reaction
Are changes in properties always evidence of a chemical change and why?
No. Boiling water is a physical not a chemical change, and yet clearly steam has very different properties than liquid water does. A chemical change is one which will change the composition or identity of the material. So not only will its properties change, but it's chemical composition will also be changed
A substance that shows a decrease in oxidation number during chemical reaction?
oxidising agent
What shows changes that take place during a chemical reaction?
A chemical equation
What is meant of '. ' in chemical reaction?
'.' shows the multiplication in chemical reaction.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
What is the relationship between a Chemical reaction and a chemical equation?
The chemical equation demonstrates the ratio of chemicals reacting and producing. Even though only minute amount of actual chemicals are reacting, the chemical equation shows which chemicals are doing what.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
Is bananas turning black if you leave them in a warm cupboard for a week a chemical reaction and why?
Yes, it is a chemical reaction, because the colour of the banana has changed, which shows that a chemical reaction has taken place. Also, if the banana has gone black and turned bad, you can't change it back to it's original form, which proves that it is a chemical reaction and not a physical reaction. Remember - A chemical reaction has definitely taken place if : It's colour has changed A gas is given off There are energy changes Or, it can't be changed back to what it used to be! :) Hope this helps!!
What tells the story of a chemical reaction?
The written statement that shows a chemical reaction is called an "equation". The representation of each reactant is called its chemical formula.
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
What info does a chemical equation provide?
A chemical equation shows a reaction between to chemicals using chemical formulas.
What is the importance of coefficients in a balanced chemical equation?
Coefficients are imortant in a balanced chemical reaction, because it shows you how much of that chemical is reactanting, and also how much is being produce to form the products.
What kind of reaction shows two reactants combining to form one new profuct?
combination reaction
Are changes in properties always evidence of a chemical change and why?
