An electron has a charge identical to that of
Answers
The smallest possible particle of an element is a atom. An electron has a charge identical to that of of a proton, but with the opposite sign.
What is atom?
The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.
Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. An electron has a charge identical to that of of a proton, but with the opposite sign.
Therefore, an electron has a charge identical to that of of a proton, but with the opposite sign.

For chemical changes like precipitation, appropriate use of a beaker is to provide space for the precipitate to form and for the color of the precipitate to be distinct.
Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
Thus, appropriate use of a beaker is to provide space for the precipitate to form and for the color of the precipitate to be distinct.

The answer would be C. :))
B. A new gas is observed in the form of bubbles
C. Red and yellow paint mixing to make orange
D. The temperature of the substance remains constant updates
Answers
To solve such this we must know the concept of chemical reaction. Therefore, the correct option is option B that is a new gas is observed in the form of bubbles.
What is chemical reaction?
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
The characteristics of chemical reaction are:
Evolution of a Gas
Change in temperature
Change in color
Formation of Precipitate
The evidence that a chemical reaction has occurred is a new gas is observed in the form of bubbles.
Therefore, the correct option is option B that is a new gas is observed in the form of bubbles.
