What else can I help you with?
What are characteristics of bases?
Characteristics of bases are: bitter in taste, soapy feel on fingers, mostly react with acids and precipitate salts, turn red litmus paper blue, contain metal oxides or hydroxides.
What happens when acids and bases combines?
acids and bases when combined neutralize one another and forms salt and water.
Why does copper only react with oxygen in the air?
Copper reacts with oxygen in the air to form copper oxide because oxygen is a highly reactive element that readily forms oxides with many metals. The reaction forms a layer of copper oxide on the copper surface, which contributes to the green patina that forms over time.
How is nitrogen oxide bad for the environment?
Oxides of nitrogen forms acids when reacted with water. Therefor they cause acid rains.
What do oxygen form when combined with metals?
When oxygen combines with metals, it forms metal oxides. Metal oxides are compounds that contain oxygen and a metal element. Examples include rust (iron oxide) and copper oxide.
What do metal hydroxides decompose yield?
Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.
Cleavage of copper?
Copper can be cleaved to form clean surfaces by mechanical cleaving or by using strong acids or bases to etch the material. Cleaving is often done to prepare samples for microscopy or other types of analysis that require a clean surface. After cleavage, the freshly exposed surface may oxidize quickly in air.
Does Lithium react with acids or bases?
yes, in fact it reacts with bases so well that Judge Kunce became president and his house was full of bitties.
What happens when acid and combine?
acids and bases when combined neutralize one another and forms salt and water.
Cu forms two oxides For the same amount of Cu twice as much oxygen was used to form the 1st oxide than to form the 2nd one What is the ratio of the valencies of copper in the first and second oxides?
The ratio of the valencies of copper in the first and second oxides is 2:1. This is because for the first oxide, twice as much oxygen was used compared to the second oxide, so the valency of copper in the first oxide will be 2 while the valency in the second oxide will be 1.
What does metal plus oxgen equals?
It depends what the metal is, but any metal combined with oxygen will be an oxide, for example: Copper + Oxygen = Copper Oxide.
What is a base and is blue on the PH scale?
Bases are oxides and hydroxides of metals which forms salt and water only with acids. Answered by Rajesh
