Introduction
Chemistry is a fascinating field that deals with the study of the composition, properties, and reactions of matter. Compounds are formed when two or more elements combine in a fixed ratio to produce a new substance with unique properties. In this article, we will explore the correct formula for a compound made of oxygen and beryllium.
Understanding the Elements
Beryllium (Be) is a chemical element with the atomic number 4 and an atomic mass of 9.012182. It is a hard, grayish-white metal that is highly toxic and has a high melting point. Oxygen (O) is a chemical element with the atomic number 8 and an atomic mass of 15.9994. It is a highly reactive gas that is essential for life on Earth.
The Law of Definite Proportions
The law of definite proportions states that a chemical compound always contains its component elements in fixed ratio by mass, regardless of its source and method of preparation. This law is a fundamental principle in chemistry that helps us determine the correct formula for a compound.
The Law of Multiple Proportions
The law of multiple proportions states that when two elements form more than one compound, the masses of one element that combine with a fixed mass of the other element are in simple whole-number ratios. This law is also a fundamental principle in chemistry that helps us determine the correct formula for a compound.
Determining the Correct Formula
To determine the correct formula for a compound made of oxygen and beryllium, we need to consider the valency of the elements. Beryllium has a valency of 2, which means it can form two bonds with other elements. Oxygen has a valency of 2, which means it can form two bonds with other elements.
Option A: BeO
Option A is BeO, which suggests that one atom of beryllium combines with one atom of oxygen. However, this formula does not satisfy the law of multiple proportions, as it does not provide a simple whole-number ratio of the masses of the elements.
Option B: Be2O3
Option B is Be2O3, which suggests that two atoms of beryllium combine with three atoms of oxygen. However, this formula does not satisfy the law of multiple proportions, as it does not provide a simple whole-number ratio of the masses of the elements.
Option C: BeO2
Option C is BeO2, which suggests that one atom of beryllium combines with two atoms of oxygen. However, this formula does not satisfy the law of multiple proportions, as it does not provide a simple whole-number ratio of the masses of the elements.
Option D: Be2O
Option D is Be2O, which suggests that two atoms of beryllium combine with one atom of oxygen. This formula satisfies the law of multiple proportions, as it provides a simple whole-number ratio of the masses of the elements.
Conclusion
In conclusion, the correct formula for a compound made of oxygen and beryllium is Be2O. This formula satisfies the law of multiple proportions, as it provides a simple whole-number ratio of the masses of the elements. The other options do not satisfy the law of multiple proportions, as they do not provide a simple whole-number ratio of the masses of the elements.
