Why do scientists say that most of the mass of an atom is located in the nucleus?

Tate the law of conservation of mass. Then apply the law to this question: What would be the total mass of the products of a reaction in which 10 grams of water decomposes into the elements hydrogen and oxygen

At 25 °c, only 0.0100 mol of the generic salt ab2 is soluble in 1.00 l of water. what is the ksp of the salt at 25 °c? ab2 (s) ↽--⇀a2 + (aq) + 2b - (aq)

what is the drag force acting on a car with a resultant force of 600N when the engine is pushing it with a force of 11,000N

What is acid? 2. define an atom?

What is the sum of the coefficients of the following balanced chemical equation? KI + Pb (NO3) 2 → KNO3 + PbI2 A) 6 B) 10 C) 18 D) 20

Which of these measurements could be the pressure of a gas? O 725K 725 mmHg 725 grams 725 meters

Propane gas (C3H8) is combusted at a constant temperature and pressure. If 34.35L of propane react, what volume of oxygen is required? What volume of carbon dioxide is produced?

How is an organism related to a population?

The anion formed from an oxygen atom is called a (n) a. oxygen ion. c. carbon dioxide. b. oxide ion. d. nitrous oxide.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.
