As part of an experiment, a student burns propane (c3h8) to produce carbon dioxide (co2) and water (h2o). she remembers that she must follow the law of conservation of matter when writing a balance chemical equation. which of these equations adheres to the law of conservation of matter? a) c3h8 + o2 -> co2 + h2o b) c3h8 + o2 -> 3co2 + h2o c) c3h8 + 3o2 -> co2 + 4h2o d) c3h8 + 5o2 -> 3co2 + 4h2o

The correct answer would be D) C₃H₈ + 5O₂ -> 3CO₂ + 4H₂O

Law of conservation of mass states that matter can neither be created nor it can be destroyed. It can change from one form to another however, the total mass of the matter remains conserved

In a chemical equation it can be infer as the mass of the reactants remains equal to the mass of the products.

Hence, the total number of elements used in a chemical reaction must remain conserve during the chemical reaction.

In the reaction C₃H₈ + 5O₂ -> 3CO₂ + 4H₂O  

3 carbon atoms are there in the reactant as well as product.

Similarly, 8 atoms of hydrogen and 10 atoms of the oxygen remain the same in reactant as well as product.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
