The correct option is C.
When writing chemical equations, the chemical symbols of the element are usually used together with numbers to indicate the ratio of each element in the chemical compounds. The additional sign is usually used in between the reactants and the products. The arrow sign in used to show the direction in which the reaction is proceeding. In the correct option given above, the arrow sign is used to indicate that the reaction is moving in the forward direction.
Answer:

two or more substances combine chemically
two or more substances combine but keep their physical properties
two or more substances combine and create an irreversible reaction
Mixtures are combination of two or more substances which can be separated based on their physical properties. Hence, option c best describes a mixture.
Mixtures are substances formed by the combination of two or more individual components. The mixing can be of physical or chemical type. The individual components can be separated using some techniques based on their physical properties.
There are both homogenous mixtures and heterogenous mixtures. In homogenous mixtures the components are uniformly mixed and form a single phase.
Heterogenous mixtures are composed of components forming different phases. They can be easily separated using simple techniques. Irrespective of the type of mixing, the physical properties of the components are maintained as such in a mixture. Hence, option c is correct.

Answer: two or more substances combine but keep their physical properties or two or more substances combine and create an irreversible reaction.
Explanation: Because i tried the other two and they didnt work so yeah thats life and i got a d on my test thx for the wrong info person before me.
Here we have to point out the necessary character of the substance needed which are used as lightning conductor.
The substance should have the following properties:
High electricity carrying capacity and less resistant.
High melting point
The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground
The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.
Answer:The lightning rod should be constructed of a metal, which is an inorganic substance.
Metals are good conductors of electricity.

i just got it right
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.
