(ii) Properties of water are entirely different from its constituents hydrogen and and oxygen. Hydrogen is combustible while oxygen supports combustion.

How can you prove something is a compound?

If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.

How can you say that water is a compound but 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. Explanation: Compounds contain two or more different elements.

Which two reasons to prove that water is a resource?

The melting point of water as well as boiling point varied on the external pressure, volume and surrounding temperature. This implies that water is a compound and not an element. This is because an element’s properties remain uniform irrespective of external conditions. -Water is stable at room conditions.

How can you prove that water is a compound Brainly?

Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). …

Is water an element or compound give reason Class 9?

Water is a compound. Compound is formed by combination of elements which are bonded together by chemical bonds.

Why is water considered a compound mention two points Class 9?

Water is considered as compound because: (i) Water is composed of two elements:hydrogen and oxygen. (ii) The ratio of hydrogen and oxygen by mass in any sample of pure water is the same. (iii) The properties of water are different from its constituent elements: hydrogen and oxygen.

Does not prove that the water is a compound?

Answer. Answer: property does not prove that water is a compound is d) Distilled water and tap water have same taste and constituents.

Is water is a compound?

Answer. Answer: property does not prove that water is a compound is d) Distilled water and tap water have same taste and constituents.

Is water a pure substance?

Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.

Is water a molecular substance?

Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). If you like, you can say that water is a molecular compound.

Why water is considered as compound and not mixture?

Water is a compound. It is made up of many elements, including hydrogen and oxygen atoms that are bonded together. Physical techniques cannot separate water into its components, hydrogen and oxygen. Chemical procedures are the sole way to split it into its parts.

What is the difference between H * * * * * * * * * * and heterogeneous mixture?

A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.

Why is water considered a compound?

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 of two hydrogens for one oxygen.

Why is water considered a compound Give two reasons?

Water is a compound because:

Water cannot be split into its constituents, hydrogen and oxygen, by physical methods. It can only be separated into its constituents by chemical processes. The properties of water are entirely different from those of its constituents.

Which of the following substance is an element?

Gold (Au) cannot be broken down into simpler substances by chemical reactions. Hence, it is an element.

Why Brass is a mixture not a compound?

Brass and bronze are made up of varying amounts of metals, depending on how it is made. The elements are not bonded in constant ratios, much like the raisins and flakes in Raisin Bran. Therefore, brass and bronze are simply mixtures of elements. Metal mixtures are called alloys.

Is water and element?

An element is a substance composed of a single type of atom. Hydrogen (element symbol H) and oxygen (element symbol O) are examples of elements. You may have heard water called “H2O.” The name refers to the chemical formula of water, H2O. So, water is made from elements, but is not itself an element.

What are the component of water?

To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature.

What is the chemistry of water?

A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled.

Is water an element True or false?

Water clearly is not an element because it consists of, and actually can be decomposed chemically into, the two substances hydrogen and oxygen, these two substances, however, are elements because they cannot be decomposed into simpler substances by any known chemical process.

What makes water pure?

Distilled water is created through the process of distillation. Basically, in the process of distillation, the pure H2O is boiled out of its contaminants. So, many of the contaminants found in water are inorganic minerals, metals etc.

Is mineral water a compound or mixture?

Answer: The molecular formula of water H20 which has two different elements Hydrogen(H) and Oxygen(O). So, it is a compound.

How do you know if water is pure?

The purity of water can be tested by evaporating it (to dryness) on an evaporating dish or by measuring its boiling point.

How does a water molecule form?

Water is formed when one oxygen atom forms a single covalent bond with two separate hydrogen atoms. This arrangement gives oxygen the two electrons it needs to fill its outer shell and allows both hydrogen atoms to receive the single electrons they need for their outer shells.

Why water is a liquid?

At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second.

What is water and its properties?

Water is a liquid at standard temperature and pressure (25 degrees Celsius and 1 atm, for liquids). Water is is tasteless and odorless. Water is transparent in the visible part of the electromagnetic spectrum. Water can act as either an acid or a base.

What is homogenous and heterogenous?

In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system, heterogeneous (also inhomogeneous) means that the properties change within the system. Any system with two phases like ice and water are said to be heterogeneous.

What is homogenous and heterogenous mixture?

By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase.

What is called heterogeneous?

: consisting of dissimilar or diverse ingredients or constituents : mixed an ethnically heterogeneous population.

Why water is considered as a compound Shaalaa?

Water is considered a compound because it is made of two elements hydrogen and oxygen combined in the ratio 1:8 by mass. Components of water cannot be separated by physical methods but can be separated by electrolysis of water.
