Answer:
The periodic table tells you the atomic number (which tells you the number of protons and electrons). It also includes the mass number, which is the sum of the protons and neutrons in the nucleus of an atom.
Answer:
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
Explanation:
Ba(OH)2 + HCl = BaCl2 + H2O is the reaction that happens.
You make an ionic compound which is soiuble in water Barium Chloride. The cation is Ba^2+ = Barium ion, Cl^ - = Chloride ion
Postive ions are cations and negative ions are anions thus
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
The correct answer is b. bimolecular
Answer:
A radionuclide is an atom that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle from the nucleus.

The existence of isotopes contradicts part of Dalton's original atomic theory because he said all atoms of a given element are identical have the same mass size and chemical properties.
Answer:
The total weight of both object is 78.56 kg.
Explanation:
Given data:
Mass of object A = 45.1 kg
Mass of object B = 33.46 kg
Total weight of object = ?
Solution:
Total weight of both subject must be the sum of weight of object A and B.
Total weight of objects = weight of object A + weight of object B
Now we will put the values of mass of object A and B.
Total weight of objects = 45.1 kg + 33.46 kg
Total weight of objects =78.56 kg
Thus the total weight of both object is 78.56 kg.
