What type of reaction is copper and nitric acid?
What type of reaction is copper and nitric acid?
oxidation-reduction reactions
Is Copper 2 nitrate a base or acid?
Copper(II)nitrate is the product of the acid-base reaction, therefore it can be designated as a salt: {eq}Cu(OH)_{2}+2HNO_{3}\rightarrow…
What happens when you add nitric acid to copper?
Nitric acid reacts with copper according to the reaction: 4 HNO3(l) + Cu(s) ==> Cu(NO3)2(s and aq) + 2 NO2(g) + 2 H2O(l) The copper nitrate salt that forms is a deep blue color. The nitrogen dioxide is a maroon vapor.
What type of reaction is copper and oxygen?
The oxidation-reduction reactions of copper metal in the environment occur in several steps. Copper metal is oxidized to copper(I) oxide Cu2O), which is red, and then to copper(II) oxide (CuO), which is black.
Is copper reactive with oxygen?
The reactivity series lists metals in order of their reactivity. Copper is the only metal apart from precious metals that will not react with water or dilute acids. It will react very slowly with oxygen.
What else can the copper react with?
Heated copper metal reacts with oxygen to form the black copper oxide. The copper oxide can then react with the hydrogen gas to form the copper metal and water.
What gas is produced in Part V of the copper cycle lab?
When it reacts with sulfuric acid, flammable hydrogen gas is released. Sulfuric acid, hydrochloric acid and sodium carbonate solution are corrosive materials that should be handled with care.
When you burned copper the product copper oxide appeared on the wire Besides copper the other reactant is explain how you know it must be oxygen Where did the oxygen come from?
Explain how you know it must be oxygen. Where did the oxygen come from? Copper oxide is the only product, and it contains copper and oxygen. One of the reactants is copper, so the other reactant must be oxygen.
What is another name for the solids formed in this lab?
A solid formed from two solutions is called a precipitate.
When you burn copper the product copper oxide appeared on the wire?
The product which forms after the reaction between copper metal and oxygen gas is copper oxide which is a black color coating on the surface of the copper. When this copper oxide reacts with hydrogen gas, then the reaction among these two reactant gives copper metal and water as products.
Which of the following best explains why you sanded the copper wire before burning it?
So, when we sanded copper wire then these impurities get removed and copper metal gets exposed onto the surface. Thus, we can conclude that you sanded the copper wire before burning it to make sure that copper metal was exposed on the surface of the wire.
What evidence of a chemical reaction did you observe?
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change.
In what kind of reaction do two or more substances combine?
synthesis reaction
Does combining two or more substances always result in a chemical reaction?
In simplest terms, a chemical change (or chemical reaction) occurs when two substances are mixed together and transform into a third substance. Not all substances react chemically when mixed together, however. For example, some substances, when mixed together, remain simply a mixture of those two substances.
In what kind of reaction do two or more substances combine to form a new compound quizlet?
In what kind of reaction do two or more substances combine to form a new compound? decomposition reaction.
Which of the following observation does not indicate that a chemical reaction has occurred?
Chemsitry Chapter 8
| Question | Answer |
|---|---|
| A chemical reaction has NOT occurred if the products have __________? | the same chemical properties as the reactants |
| Which observation does NOT indicate that a chemical reaction has occurred? | change in total mass of substances |
In what type of reaction does two reactants form one product?
Synthesis Reactions
What happens when nickel is added to a solution of potassium chloride?
activity. Predict what happens when nickel is added to a solution of potassium chloride. No reaction occurs. atoms lose electrons.
What happens when lead is added to nitric acid?
Lead when reacted with nitric acid forms lead(II) nitrate, nitrogen oxide and water. Lead reacts slowly nitric acid, HNO3. Nitrogen oxides are formed together with lead(II) nitrate, Pb(NO3)2.
Is KCl soluble in water?
Water
