Water is one substance that is compound. It contains two parts hydrogen and one part oxygen, which makes it a compound substance.
A compound containing sand and gold could be a mixture of the two substances, where the gold particles are mixed with the sand particles. If water and iodine are added to this mixture, the water could dissolve the iodine to form a solution, leaving the sand and gold particles unchanged.
The term you are referring to is "substance." Substances can be pure elements, such as oxygen or gold, or compounds, such as water or table salt.
Sodium can be separated into simpler substances only by chemical means. Water, salt, and gold are pure substances that cannot be separated into simpler substances by chemical means.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
No, it's pure gold. It is an element. However, most jewelry is a compound of gold and silver or other metals to make it harder and stronger.

A substance that cannot be broken down is a pure substance
water
Gold is not. Gold is an element that cannot be broken down further.The rest are substances that consist of multiple elements bonded together:Sugar (common sugars) is either C6H12O6 or C12H22O11Salt is NaClWater is H2O
Sodium can be separated into simpler substances only by chemical means. Water, salt, and gold are pure substances that cannot be separated into simpler substances by chemical means.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
Water is a compound because it is composed of : hydrogen and oxygen. Each of these elements loses its original properties to form a compound. Gold is an element because it is 100 % gold and found in that form.
No, it's pure gold. It is an element. However, most jewelry is a compound of gold and silver or other metals to make it harder and stronger.
salt water
Steel is an alloy made mainly of iron, carbon, and other elements. Water is a compound composed of hydrogen and oxygen. Oxygen is a chemical element, and gold is a precious metal. They are all distinct substances with different properties.
A sugar is a compound that consists of carbon, hydrogen, and oxygen atoms. Salt is a compound composed of sodium and chloride ions. Gold is a chemical element and not a compound. Water is a compound composed of hydrogen and oxygen atoms.
