Water is a compound because it is made up of water molecules . There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion
Why is water considered as a compound of two points?
Water is a compound and a compound forms whenever two or more atoms form a chemical bond with each other . The chemical formula for water is H 2 O which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms.
Why water is considered a compound and not a mixture?
Answer: Water is a compound and not a mixture because Its properties are completely different from that of oxygen and hydrogen, its constituent elements .
What is difference between element and compound?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. ... Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction .
What is water a universal solvent?
Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid . ... Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
Is dry ice a mixture?
Dry ice is a compound consisting of one carbon dioxide molecule chemically bonded to two molecules of oxygen and not an element or a mixture .
Is Alum is a mixture?
Ans: Air is mixture of gases. Alum is a addition compound (K 2 SO 4 .
Is milk mixture or compound?
Thus, milk is a mixture of fats, proteins, sugar and water which are mixed irrationally. Thus, milk is not a pure substance or a compound that is made up of one type of atom or molecule. But milk is a mixture of fats, proteins, sugar and water which are mixed irrationally. Thus, milk is a mixture.
What are 2 differences between an element and a compound?
Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions . ... Compounds are represented by their chemical formula. For example, salt is represented by the formula NaCl.
What is the difference between elements and compounds examples?
Elements are formed with the same types of atoms . For example, we are considering oxygen (O2). Oxygen is formed with two oxygen (O) atoms of the same kind, atomic number and properties. Compounds are constructed with more than one type of atom.
How do you classify matter?
Matter can be broken down into two categories: pure substances and mixtures . Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
What property makes water the universal solvent?
Water molecules have a polar arrangement of the oxygen and hydrogen atoms —one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. This allows the water molecule to become attracted to many other different types of molecules.
Is salt a solute?
In salt solution, salt is the solute . A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. ... For each solute and solvent, there is a limit to the mass of solute that will dissolve in a particular volume of the solvent.
What can water dissolve?
Everything dissolves in water. Stone, iron, pots, pans, plates, sugar, salt, and coffee beans all dissolve in water. Things which dissolve are called solutes and the liquid in which they dissolve is called a solvent.
What happens if you touch dry ice?
Always handle Dry Ice with care and wear protective cloth or leather gloves whenever touching it . An oven mitt or towel will work. If touched briefly it is harmless, but prolonged contact with the skin will freeze cells and cause injury similar to a burn.
What is dry ice formula?
Dry ice is not formed due to chemical change. Its chemical name is solid CO2 . or frozen carbon dioxide. – The chemical formula of dry ice is CO2. .
