if oxidation states change, it is a redox reaction
An example of a redox reaction that is also a combination reaction is the formation of hydrogen fluoride (HF) from hydrogen gas (H2) and fluorine gas (F2). The hydrogen is oxidized from an oxidation state of 0 to +1, while the fluorine is reduced from an oxidation state of 0 to -1. This reaction is a combination reaction because two elements combine to form a single compound.
Redox doesn't use indicators. It uses the natural colouration of the chemicals involved to determine the endpoint and titre. Acid-base titrations use a pH indicator, as otherwise there is often no way to tell the difference between an acidic solution and a basic one.
The reaction is endothermic.
the reaction is exothermic
right! (zn) stands for zink and (so4) stands for sulfuric acid so....... u join them up and say it together and by the way were ever u go in the internet if you type what does znso4 mean?!?! it will never tell you so cut it -cheers- hope you understood
In a redox reaction, the substance that is oxidized loses electrons. To identify which substance is oxidized, look for an increase in oxidation number or loss of hydrogen atoms or gain of oxygen atoms in the reaction. The substance that undergoes these changes is the one that is oxidized.

Just wait. Be sure you tell the person what had happened.
well....... I'm not sure. can u tell me the answer =)

You are the only person who can tell YOUR reaction.
There is not really a way to tell for sure. I would personally just go with the majority. The testimonies are coming from regular people and everyone may have a different reaction to the product.
That you probably want to tell him you love him. Possibly you are worried that it is too soon and not sure what his reaction would be.
You need to calculate the yield of the reaction.
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
