What reaction shows a chemical changes producing a gas?
2AgNo3OH(I) + 3O2(g) -> 2CO2(g) + 4H2O(l) (from Apex)
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 shows in reaction that chemical change has take place?
a reaction has taken place when one or more of the following occur : - a new substance is formed - change in colour - precipitate is formed
What shows a reaction in a solution consisting of only those particles directly involved in the chemical change?
Net-Ionic Equation

'.' shows the multiplication in chemical reaction.
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.
Which reactions shows a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
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
What shows in reaction that chemical change has take place?
a reaction has taken place when one or more of the following occur : - a new substance is formed - change in colour - precipitate is formed
What shows a reaction in a solution consisting of only those particles directly involved in the chemical change?
Net-Ionic Equation
What shows a chemical change producing a solid?
2AgNO3(aq) + CaBr2(aq) 2AgBr(s) + Ca(NO3)2(aq) estion…
What shows changes that take place during a chemical reaction?
A chemical equation
What are the five observations of chemistry that shows that a chemical reaction have taken place?
Formation of a precipitate; change in color; change in temperature; formation of a gas; emission of light.
