within other compounds. Two hydrogen atoms and an oxygen atom make one molecule of water-in formulae it is written as H2O). At ambient temperatures‚ the water molecules are at liquid state. This differs with other molecules like hydrogen sulphide which have slightly greater molecular masses and are gasses at room temperatures. The construction of the molecule creates a polar nature. This is in which the electrons are shared unequally. The oxygen atom is larger than the hydrogen atom. The oxygen nucleus

rain? Acid rain is the term for pollution caused ... of one oxygen atom and two hydrogen atoms. The oxygen atom also called the "apex of the water molecule" bears a slight electronegative charge while hydrogen possesses a more positive one (Kirk 225). Because of the opposite charges attract‚ the water molecules are drawn together. When an oxygen atom is linked to a molecule’s hydrogen atom‚ a bond called a hydrogen bond is formed (Kirk 256). There are several types of water molecule such as liquid

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

replace Hydrogen because it is more reactive. Copper + Hydrochloric Acid: Copper will not displace Hydrogen because copper is more reactive. Magnesium + Hydrochloric acid: Magnesium will displace Hydrogen because it is more reactive and end up as Magnesium Chloride + Hydrogen. Sodium + Hydrochloric acid: Sodium will displace Hydrogen because it is more reactive and end up as Sodium Chloride + Hydrogen. Apparatus:

Hydrogen peroxide is a substance that contains two hydrogen atoms and two oxygen atoms. Hydrogen peroxide is a weak acid and does not react formally with base substances. Catalase is found in many foods like beef liver‚ carrots‚ wheat sprouts‚ and potatoes‚ and more. Catalase is released when a protein is coming into the stomach a protein catalase goes and transforms the protein into food for human’s internal cells. Bubbles in an experiment where a raw potato is put into hydrogen peroxide

compounds that contain‚ primarily‚ carbon and hydrogen. Whereas the organic compound can contain other elements‚ the bond between carbon and hydrogen are what makes a compound organic. The original organic chemistry was defined the study of compounds by living organisms. Inorganic chemistry is the chemistry that deals with the properties and behavior of inorganic compounds. Inorganic compounds are those that are not biological‚ and not containing any hydrogen and carbon bonds. We can state that inorganic

magnesium salt and hydrogen. For example: Mg + 2HCl Mg + H2SO4 MgCl2 + H2 MgSO4 + H2 I discovered from an A’ level text book (A-level Chemistry by Ramsden) that nitric acid doesn’t usually give hydrogen‚ but may do with magnesium if the acid is cold and dilute. The book didn’t say how dilute the acid had to be. Other products may include oxides of nitrogen. I know that some acids are weak and some are strong. A strong acid is one which ionises fully in solution to give hydrogen ions and‚ for example

The IUPAC system of naming is different from the common system‚ because it uses a series of prefixes and suffixes to name a certain compound. This system is also highly favored because its way of naming compounds is not only easier to understand and unambiguous‚ but it is also usually shorter than the common way. The IUPAC system’s uses include naming binary compounds between a metal and nonmetal‚ naming binary compounds between two nonmetals‚ naming polyatomic ions‚ and naming acids and bases

Tables: Hydrogen Step B: Describe the zinc and acid reaction. As placing a small piece of Zn(mossy zinc) metal into the test tube containing the diluted HCI(Hydrochloric Acid) solution‚ gas bubbles rose from the solution slowly at the beginning and vigorously in process of time. As this reaction continued for a long time‚ transparent solution turned into white opaque color and black precipitates were formed and floated. Step G: Record your observations with the flame and the hydrogen gas. When
