Answer:
The reaction would be 1500n (equal reaction)
Explanation:
This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.
It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.
Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.
An electron is a negatively charged subatomic particle.
Uranium-235 is a naturally occurring isotope of uranium, an element characterized by having 92 protons in its nucleus.
As all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235.
Thus, Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.

Answer:
Uranium is element 92, so unionized, it has 92 protons and electrons. U-235 is an isotope with a total of 235 nucleons, so subtract 92 to get 143 neutrons.
Explanation:
(B) 100
(C) 15
(D) 25
(E) 30
MC₂H₄O₂ = 2 * 12 g/mol + 4 * 1 g/mol + 2 * 16 g/mol = 60 g/mol
c = 0.5 mol/L
V = 1 L
n = c * V
n = 0.5 mol/L * 1 L = 0.5 mol
m = n * M
m = 0.5 mol * 60 g/mol = 30 g/mol
answer E
(-_-(-_-)-_-)
The aspects of Dobereiner’s triads that agreed with the modern table where elements were arranged together with similar properties, and the aspects that did not match were the periodic table arranged in the rising of their atomic number.
Dobereiner’s triads were the arrangement of chemical elements on the basis of their similar physical and chemical properties, this was called the old periodic table. It was given by German chemist Johan Wolfgang Dobereiner.
The modern periodic table is arranged on the basis of their atomic number The elements of Dobereiner's triads were placed based on the order of increasing atomic masses.
Thus, All known elements could not be grouped into triad groups based on their properties.
