Which of the following substances Cannot be decomposed by chemical change?

Which of the following substances Cannot be decomposed by chemical change?

Argon Ar, is an element, one of the noble gases. Because it is an element it can’t be broken down chemically. Breaking the atoms down into subatomic particles requires nuclear reactions. Argon cannot be decomposed by chemical change.

What substance Cannot be broken down by a chemical reaction?

A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound.

Which substance Cannot be decomposed into simpler substances ammonia aluminum methane methanol?

The answer is (b) aluminum. The pure substances ammonia, methane, and methanol are all compounds that can be decomposed or broken down into simpler…

Can co2 be decomposed by a chemical reaction?

Splitting carbon dioxide (CO2) into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy. If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient.

Which substance Cannot be decomposed by chemical means ammonia?

Among the given substances, the one that cannot be broken down by a chemical change is arsenic. It is one of the elements which is present in the simplest units. Ammonia, ethane and propanal are the three compounds, and they break down by a chemical change to give simple elements.

Which substance Cannot be decomposed into simpler substances 1 Ammonia nh3 2 aluminum AL 3 Methane ch4 4 methanol ch3oh?

The answer is (b) aluminum.

Can co2 be decomposed by chemical means?

Splitting carbon dioxide (CO2) into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy. Consider the proposal as a chemical reaction: CO2 plus energy yields carbon and oxygen. This formula essentially reverses coal combustion (carbon plus oxygen yields CO2 and energy).

Which substance Cannot be decomposed by chemical means 1 C 2 CO 3 CO2 4 c3o2?

Answer: Elements are those pure substances that cannot be decomposed by ordinary chemical means such as heating, electrolysis, or reaction. Gold, silver, and oxygen are examples of elements. Compounds are pure substances formed by the combination of elements; they can be decomposed by ordinary chemical means.

Is aluminum Cannot be decomposed into simpler substance?

What is a basic substance of matter that Cannot be broken down?

An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance.
