What do compounds always contain exact ratios of?
elements
What are equivlent ratios?
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios
What are the three types of ratios?
1 - Activity ratios 2 - Profitability ratios 3 - Liquidity ratios
What are 3 types of ratios?
1 - Activity Ratios 2 - Liquidity ratios 3 - Profitability ratios
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
Do mixtures contain exact ratios of elements?
No, they do not.
What shows which elements are in compound and their ratios?
A formula shows constituent elements and their ratios. In the formula Al2O3, you can see aluminum and oxygen bonded in a 2-3 ratio.
What is an abbreviation for elements and their ratios in a compound?
chemical formula
What do compounds always contain exact ratios of?
elements
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
What shows elements are in a compound and their ratios?
This is the chemical formula.
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
The noble gases, such as helium, neon, and argon, were difficult for Mendeleev to add to his table as they were found to be chemically inert and did not easily combine with other elements in fixed ratios. This challenged the periodicity of his table, which was based on the repeating patterns of chemical properties.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
Do you simplify empirical formula ratios?
Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
Which two elements are in sulphate?
Sulfur and oxygen are the two elements in sulfate.
What is matter made of elements combined in changing ratios?
You think probable compounds.
