Answer: C) a redox reaction that produces an electric current
Explanation:
Chemical cell is a device which is used for the conversion of the chemical energy produced in a redox reaction into the electrical energy. The cell consists of the negative terminal called as anode where oxidation takes place and a positive terminal called as cathode where reduction takes place.
Electrolytic cell is a device which is used to carry out chemical reactions by the use of electrical energy. The cell consists of the negative terminal called as cathode where reduction takes place and a positive terminal called as anode where oxidation takes place.

Explanation:
Answer:
119
Explanation:
Tin is present in group sixteen. Its atomic number is 50 and atomic weight is 119 amu.
The atomic number is the number of electrons or number of protons. The atomic mass is equal to the sum of number of protons and number neutrons.
Tin have 50 protons and 69 neutrons.The atomic weight will be 50+69 = 119 amu.
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons.
Answer:
las plantas
Explanation:
Las plantas son los seres vivos capaces de transformar energía luminosa utilizando agua y dióxido de carbono (CO₂) en energía química en forma de moléculas llamadas carbohidratos. El proceso a través del cual realizan esto se denomina fotosíntesis, y para ello requieren un pigmento de color verde denominado clorofila, el cual es necesario para captar la energía luminosa proveniente del Sol.
Answer is: Reactants and products are written in words; reactants are on the left, products are on the right side of reaction.
For example, balanced chemical reaction for cellular respiration (convert biochemical energy):
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O or:
glucose + oxygen → carbon dioxide + water.
Glucose and oxygen are reactants and carbon dioxide and water are products of reaction.
This reaction is exothermic (energy is released).
Word equation is a chemical reaction expressed in words rather than chemical formulas.
