1) Decomposition reactions. In this type of reaction, a compound is broken down into simpler compounds.
Option B is a decomposition reaction
B) ____ KClO3 → ____ KCl + ____ O2
Higher concentration of reactants equals faster rate of reaction. Reactions occur when particles collide effectively, and by increasing the concentration of reactants, you increase the number of effective collisions, thereby making the reaction occur faster.
Because all atoms are made from the same particles which are protons, neutrons, and electrons.

Answer:
A beam balance is an example of a first class lever.
Explanation:
A beam balance is an example of a first class lever. In a first class lever, the fulcrum is between the effort (force) and the load. The effort (force) moves over a large distance to move the load a smaller distance.
Other examples of first class lever are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance etc.
