What does the state symbol (aq) mean when written after a chemical compound in a chemical reaction?
The state symbol aq means it dissolves in water when it is written after a chemical compound in a chemical reaction.
What does a delta symbol mean in a reaction?
The delta symbol in a chemical equation stands for "change". Since you have to break and reform the bonds between atoms in molecules to have a chemical reaction there is going to be a change, whether it be in the thermal energy, chemical energy, phase of the matter etc.
In a chemical equation cr means what?
it means crystalline
Is a glow stick that produces light a chemical change?
Yes, a glow stick produces light by means of a chemical change.
Why is triangle symbol used in chemical reaction?
A triangle symbol in a chemical reaction formula means that there is heat supplied to the reaction. The triangle is typically placed above the arrow between reactants and products. Sometimes the word "heat" is also written above the arrow.

What means a chemical reaction that produces heat as products are formed?
Exothermic
What is chemical reaction in baking a cake?
A cake produces a permanant colour change and a slight change in weight after baking. That means, It's a chemical reaction.

it means crystalline
What is the thing that not need fire for burn?
When we talk about "burning" it generally means a chemical reaction with oxygen from the air, which produces heat. Nuclear scientists and engineers also talk about "burning" or "burnup" of the nuclear fuel, in this case there is no fire or chemical reaction, so perhaps this is what you have in mind.

When you mix yeast and hydrogen peroxide does the mixture get warmer?
Yes, the mixture does get warmer! It is called an exothermic chemical reaction, which just means it gives off heat. It is the opposite of an endothermic reaction, which means it absorbs heat. The reaction between hydrogen peroxide(C2H2) and yeast produces oxygen. Hope this answers your question!
What is a cemical reaction?
it is actualy chemical reaction and it means the interchange between two chemicals
What does symbol mean on the periodic table mean?
The symbol on the periodic table means the abrevitation of the chemical element. For example, the chemical element symbol Pm stands for Promethium.
