∙ 15y agoFehling's test differentiates between aldehydes and ketones. Aldehydes can be oxidized by Cu2+ in the presence of a strong base to form carbonic acids. Ketones cannot be oxidized by this reaction. When the Cu2+ oxidizes the aldehydes it is reduced to Cu+, and forms the compound Cu2O, which is a reddish precipitate. That is how you know you have an aldehyde. Fehling's reagent is usually formed by mixing CuSO4, sodium citrate, and sodium carbonate. The carbonte is used to raise the pH, but doing so would normally form Cu(OH)2, a precipitate. That is where the sodium citrate comes it---the citrate complexes the Cu2+ ions and prevents them from precipitating.

Reaction that break apart large molecules are involved in which type of digestion?
chemical
What does the coieffecient in a chemical equation tell you?
The number of that type particle involved in the reaction.
What type of chemical reaction is always involved in the extraction of metal from its ore?
Reduction
What is the chemical weathering symbol equation?
A general equation doesn't exist; this depends on type of the chemical reaction involved.
Atoms are what When a chemical reaction takes place?
It depends on the type of chemical reaction. A reduction-oxidation reaction (redox reaction) involves the transfer of electrons, thus electrons are involved, for example2Mg(s) + O2(g) > 2MgO(s)However, reactions involving acids or bases involve the movement of protons (acids are proton donors, bases are proton acceptors) for example:HCl(aq) + H2O(l) > Cl-(aq) + H3O+(aq)Furthermore, there are nuclear reactions which can involve almost any particle. Therefore, the type of reaction determines the particle or type of particle involved.
Define the type of chemical reaction involved in the formation of a peptide linkage between two amino acids and state the other product in addition to a dipetide?
The type of chemical reaction involved is called the "dehydration synthesis reaction".

The type or reaction takes place when one element reacts with a compound to form a new compound and a different element is a?
it's single-replacement. I took a test with a question like that and got 100%
What is the type of reaction is involved in many of the chemical reactions of photosynthesis?
anabolic
What type of reaction occurs with copper II sulfate and sodium phosphate?
The reaction is called a Metathesis Reaction or double-decomposition reaction. In this type of reactions cations and anions of the substances involved change partners.

What information can a chemical equation reply?
- what are the reactants - which are the products - the quantity of each chemical involved - the type of reaction
What happens to the atoms of an object or a substance during a chemical reaction?
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
