## Which two compounds are examples of the law of multiple proportions?

There are compounds made up of the same elements, like carbon monoxide (CO) and carbon dioxide (CO2). Both compounds are made of carbon (C) atoms and oxygen (O) atoms; however, the ratios of carbon and oxygen in each compound is different. This illustrates the law of multiple proportions.

## Is FeO and Fe2O3 multiple proportions?

## What is the law of constant proportions write with an example?

Law of constant proportions

The law of constant composition says that, in any particular chemical compound, all samples of that compound will be made up of the same elements in the same proportion or ratio. For example, any water molecule is always made up of two hydrogen atoms and one oxygen atom in a 2 : 1 ratio.

## What is the mass ratio of water?

Hydrogen and oxygen combine in a ratio of 1:8 by mass to form water.

## What is the ratio of oxygen to iron in the compound Fe2O3?

Percentage composition Percentage composition is the percentage by mass of each element in a compound. For example, the compound iron (iii) oxide, Fe2O3 has a percentage composition of iron 69.9% and that of oxygen 30.1%.

## What is the proportion explain give an example?

Two ratios are said to be in proportion when the two ratios are equal. For example, the time taken by train to cover 50km per hour is equal to the time taken by it to cover the distance of 250km for 5 hours. Such as 50km/hr = 250km/5hrs.

## What is law of constant proportion explain with an example Brainly?

According to law of constant proportions: A given compound always contains exactly the same proportion of elements by mass. Example: Water is a compound of two inflammable gases hydrogen and oxygen which are present in the fixed ratio of 2:1 by mass.

## What does law of multiple proportions states?

law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

## What are 3 types of proportion?

• Continued Proportion.

## What are the 4 properties of proportions?

The following are the important properties of proportion: Addendo â€“ If a : b = c : d, then a + c : b + d. Subtrahendo â€“ If a : b = c : d, then a â€“ c : b â€“ d. Dividendo â€“ If a : b = c : d, then a â€“ b : b = c â€“ d : d.

## What is the example of Partitive proportion?

Let us say that the amount of total profit procured in a month is equal to INR 6000. This means that according to partitive proportion the first friend would receive INR 1000, the second friend would get INR 2000, and the share of the third friend from the total profit would be equal to INR 3000.

## How is ratio and proportion used in real life?
