Answer:
CO₂
Explanation:
The product of the reaction is CO₂.
In a chemical reaction, the product is the substance usually found on the right hand side of the expression.
Reaction equation is given as;
C + O₂ → CO₂
In this reaction, C and O₂ are the reactants
CO₂ is the product of the reaction.
A 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.
Density is defined as a measurement of how tightly packed the mass is within a substance or object. The concept of density is crucial because it enables us to predict which compounds will float and which ones will sink in a liquid. As a rule, objects float as long as their density is lower than the liquid they are placed in.
The density of a substance is determined by the mass, size, and arrangement of its atoms. Density is calculated by dividing a substance's mass by its volume.
Density = Mass / Volume
Given Mass = 12.5 g
Volume = 5.0 ml.
Density = 12.5 g / 5.0 ml
Density = 2.5 g / ml
Thus, a 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.

The particle that has the least mass is a beta particle.
If we look at the particles listed individually, we can see that the proton and the neutron are both massive particles found in the nucleus of an atom. They are responsible for the mass of the atom. An alpha particle is just of the same mass as a helium nucleus.
A beta particle is actually an electron. Recall that an electron has negligible mass.The mass of an electron is about 1/840 times that of the proton.

The least massive particle among alpha particles, neutrons, beta particles, and protons is the beta particle (also known as an electron). Its mass is so small that it would take about 1800 electrons to equal the mass of a single proton or neutron.
The masses of the different particles are as follows - protons and neutrons are heavier particles with a mass of 1.0073 and 1.0087 amu respectively, while an alpha particle, which is a high-energy helium nucleus, has a mass number of 4 (which makes it heavier than a proton and neutron). Compared to these particles, the beta particle is a high-energy electron and has a much lighter mass.
Specifically, the beta particle, or electron, is the least massive among the list, with a light particle mass of about 0.00055 amu. This means that it would take about 1800 electrons to equal the mass of a single proton or neutron. So, to answer your question, when comparing an alpha particle, neutron, beta particle (electron), and a proton, the beta particle (electron) is the particle with the least mass among them.
