What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
how is it separated into different compounds?
what do you mean
What is equivalent ratios mean?
ratios that r the same
What does it mean when two ratios form a proportion?
When two ratios form a proportion, the ratios are equal
What does it mean if the cross products of two ratios are not equal?
The ratios are not equal.
Does the compounds C2H2 and C6H6 have the same percent composition by mass?
It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
What does this definition mean A ratio of equivalent values used to express the same quantity in different units?
It could be the definition of equivalent ratios.
How many different types of compounds are there?
Well depends what you mean by how many different types of compounds. In total? Or type 1 , and 2 etc. there is Type 1-Binary Compounds Type 2- Binary Trans-metallic Compounds Type 3- Binary Molecular Compounds Type 4- Ternary Compounds etc. these contains vast amounts of compounds so gives you an idea.
Do isotopes of the same element differ in mass number?
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
What does compounds mean in science?
In science, compounds are substances made up of two or more elements chemically bonded together in fixed proportions. These compounds have unique properties different from their component elements.
Does mass and volume mean the same?
no, different things being measured
How come the relative atomic mass can be a fraction?
The relative atomic mass is the mean mass of the isotopes of an element. Since, by definition, these have different numbers of neutrons, their masses are different. This results in fractional values.
