### Which Law Would You Use To Compare Co And Co2?

Law of multiple proportions, as both compounds are formed from the same elements but with different composition. CO2 will contain the highest percent by mass of oxygen in the compound as it contains 2 oxygen atoms.

### Is CO and CO2 illustrate the law of multiple proportion?

The correct option is A True.

#### Which law explains that in carbon dioxide?

Conservation of Energy and Mass The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.

1. Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed.
2. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
3. Teach about the conservation of energy and mass with these classroom resources.

## What does the law of multiple proportions account for?

Home Science Chemistry Alternate titles: law of simple multiple proportions 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.

For example, there are five distinct oxides of nitrogen, and the weights of oxygen in combination with 14 grams of nitrogen are, in increasing order, 8, 16, 24, 32, and 40 grams, or in a ratio of 1, 2, 3, 4, 5. The law was announced (1803) by the English chemist John Dalton, and its confirmation for a wide range of compounds served as the most powerful argument in support of Dalton’s theory that matter consists of indivisible atoms,

### What law supports the statement the mass ratio of C to O in CO is 3 4?

In chemistry, the law of multiple proportions states that if two elements form more than one compound, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers.

This law is also known as: Dalton’s Law, named after John Dalton, the chemist who first expressed it. For example, Dalton knew that the element carbon forms two oxides by combining with oxygen in different proportions. A fixed mass of carbon, say 100 grams, may react with 133 grams of oxygen to produce one oxide, or with 266 grams of oxygen to produce the other.

### The purpose of comparative law

The ratio of the masses of oxygen that can react with 100 grams of carbon is 266:133 = 2:1, a ratio of small whole numbers. Dalton interpreted this result in his atomic theory by proposing (correctly in this case) that the two oxides have one and two oxygen atoms respectively for each carbon atom.

1. In modern notation the first is CO ( carbon monoxide ) and the second is CO 2 ( carbon dioxide ).
2. John Dalton first expressed this observation in 1804.
3. A few years previously, the French chemist Joseph Proust had proposed the law of definite proportions, which expressed that the elements combined to form compounds in certain well-defined proportions, rather than mixing in just any proportion; and Antoine Lavoisier proved the law of conservation of mass, which also assisted Dalton.

A careful study of the actual numerical values of these proportions led Dalton to propose his law of multiple proportions. This was an important step toward the atomic theory that he would propose later that year, and it laid the basis for chemical formulas for compounds.

### What is the relationship between CO and co2?

WHAT ARE THE KEY DIFFERENCES BETWEEN CARBON MONOXIDE AND CARBON DIOXIDE? – Both of these gases have a lot of similarities – both CO 2 and CO are odourless and tasteless. Elevated levels of both gases can cause health problems and even death. The critical chemical difference is that CO 2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom.

1. Carbon dioxide is non-flammable, whilst carbon monoxide is not – we certainly wouldn’t encourage you to light a match in order to determine which gas is which.
2. Carbon dioxide naturally occurs in the atmosphere at about 400 parts per million – humans and animals breathe in oxygen and exhale carbon dioxide – we can tolerate a small amount of it.

However, carbon monoxide does not occur naturally in the atmosphere and can cause health problems even in low concentrations. The density of both gases is also different. Carbon dioxide is heavier than air and gas detectors should be put nearer the ground, whereas carbon monoxide is slightly lighter and detectors should be placed higher up.

## What is the law of conservation and law of constant proportion?

The law of conservation of Constant Proportions is also known as Law of Definite Proportions. It was Given by J, Proust in 1799. This law states that – A pure chemical compound is always made up of the same elements combined together in a fixed (or definite) proportions by mass.
