Answer:
It is due to the nature of the reactants
Explanation:
To ignite a solid, we require more heat component compared to liquids and gases. For ignition to occur, oxygen gas combines with a reactant in most cases.
Some factors affect the rate rate at which a chemical proceeds. One of the factors is the nature of reactants.
The solid phase is very slow while the gaseous phase is rapid and fast.
solid phase < liquid phase < gas phase
Gases are free and the molecules move in all direction. They easily combine and react very fast.
Answer: dominant
explanation: The dominant Gene wins because it overpowers the recessive gene.
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO 3) than the organic is a sedimentary rock composed largely of the minerals calcite and araganite.
