What is the chemical combination of two or more elements in definite proportions?
This is a chemical compound.
What are the 2 elements chemically linked in definite proportions called?
This is a chemical compound (a molecule).
Are the elements that make up a compound joined in a fixed proportion?
This is an old rule (Law of definite proportions) not valid for nonstoichiometric compounds.
How are experimental data used to show that compound obeys the law of definite proportions?
The Law of Multiple Proportions states that two or more compounds may be made from the same elements but each compound will obey the Law of Definite Proportions. Combining two elements to create another element can only be done with precise measurements of each element or another element would be created instead of the one intended.
Can the proportions of magnesium and oxygen in magnesium oxide be changed?
No. Magnesium oxide, MgO, is a compound, which means it is a pure substance, in which the magnesium and oxygen are present in definite proportions, in this case 1:1. This is in accordance to the law of definite proportions, which states that every pure substance always contains the same elements combined in the same proportions by weight. Also, magnesium ions have a charge of 2+ and oxide ions have a charge of 2-, so that one magnesium ion combined with one oxide ion balances to an overall charge of zero.
What term describes a substance formed by the combination of two ore more elements in definite proportions?
Compound
When two or more different elements joined together in fixed proportions is known as?
A compound is the pure substance formed from the chemical combination of two or more different elements in a fixed ratio.
What is the chemical combination of two or more elements in definite proportions?
This is a chemical compound.
What is a substance formed by the combination of two or more elements in definite proportions?
A chemical compound. The combination of two or more elements in definite proportions forms a compound. For instance, hydrogen and oxygen combine in a two to one ratio in order to form water. Similarly, one sodium atom reacts with one chlorine atom to form the ionic compound sodium chloride.
Why is water not a compound?
Water most definitely IS a compound! It is a compound composed of hydrogen and oxygen atoms chemically bonded in a definite proportion of 2H:1O. The molecular formula is H2O. A compound is a pure substance composed of different elements chemically bonded in definite proportions.
When two or more elements bond together in definite proportions?
When forming a chemical compound.
When two or more elements bond together in definite proportions they form a?
Compound.
What are the 2 elements chemically linked in definite proportions called?
This is a chemical compound (a molecule).
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
Is NaCI a compound or a mixture?
Compound- two or more elements bonded to each other in definite proportions NaCl is a compund
Who said Any sample of a chemical compound will contain the same elements in the same proportions?
This is the law of definite proportions: Joseph Proust, 1806.
Who said that a given compound always contains the same elements in the same proportions by mass?
chemist named Proust
