I believe the correct answer from the choices listed above is option A. The topic that the teacher is talking about would be distillation of a mixture. Gasoline is processed by distillation. Hope this answers the question. Have a nice day.
Answer:
Nitrogen monoxide and oxygen are called the reactants
Explanation:
Step 1: Given data
Nitrogen monoxide = NO
Oxygen = O2
Step 2: Balanced equation
2NO + O2 → 2NO2
This means that 2 moles of NO will be consumed and and 1 mole of O2 to produce 2 moles of NO2
This means NO2 is the prodcut that is produced.
NO +O2 react with eachother, to form NO2
This means nitrogen monoxide (NO) and Oxygen (O2) are called the reactants.
Answer:
Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
The speed of sound depends on the elasticity and density of the medium through which it is traveling, a.k.a sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
