Answer:
Reactants starts the chemical reaction and gives right to the product either by thermal decomposition or in the presence of a catalyst.
Explanation:
Reactants and products contain the same atoms, but they are rearranged during the reaction, so reactants and products are different substances.
Answer:
The properties of reactant are:
1. it contains the same atoms
2. it describes the pathway of the reaction.
Answer:
Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.
B. helium
C. school glue
D. washing powder
B)oval window
C)ear canal
D)Hammer
Answer: cochlea
The cochlea is responsible for turning sound waves which is what makes you hear.
Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.

The pencil's slim, lightweight structure and graphite core, known for its unique layering of carbon atoms via sp²-hybrid orbitals, are essential for its function of writing or drawing.
The structure of a pencil is tightly linked to its function. The pencil is made of a slim wooden case which is lightweight and easy to grip, enabling convenient writing or drawing. This wooden case houses a graphite center, the 'lead' of the pencil.
Why graphite? It is important to consider the properties of graphite. Graphite is soft and slippery, which allows it to easily leave marks on paper. Its structure consists of layers of carbon atoms, each connected to three others in a planar arrangement through sp²-hybrid orbitals. This layering structure allows for the graphite to be gradually worn away as the pencil writes, leaving a trail on the page, while the pencil reverts to its equilibrium state due to the torque produced by its weight.
So, in simple terms, the slim size, lightweight nature, and graphite core (with its unique structure and properties) are integral to a pencil's function of writing or drawing.
