The answer to the question given above is letter A. Light
Light is considered a load of the parts of a circuit. <span>The load in a circuit can be
any electrical device that converts electrical energy into other usable forms
of energy such as a <span>light bulb.
>></span></span><span>Energy sources include
batteries and generating stations
>>switch-</span><span>is
used in electric circuits to allow the circuit to be turned on and off.</span>
Explanation:
1) Atoms can not be subdivided. It has been changed as it is possible to divide an atom into Protons, Neutrons and Electrons as well as other smaller particles.
2) The regulations for the chemical mixture have always been altered to the rules for the chemical combination in the creation of organic compounds may be denied.
3)Atoms are of a particular element are identical in all respects i. e. they have same mass and similar properties.
It was modified. And according. to new search;
Atoms of the same element may not be always identical.
This means that they mixed .
Answer is: coefficient is one.
Chemical reaction: SiO₂ + 4HF → SiF₄ + 2H₂O.
Reaction is balanced when there are equal numbers of elements in both side of the chemical reaction.
HF - hydrofluoric acid, <span>highly corrosive, dissolves many materials.</span>
SiF₄ - silicon tetrafluoride.
