Once the solution is prepared, water is now considered as the solvent of the solution. On the other hand, NaCl is the solute. The solvent is a substance that dissolves other substances. It has a larger composition with respect to the other components in the solution.
Bohr's model of the atom states that electrons orbit an atom's nucleus in electron shells of increasing energy. The electrons are free of physical contact with the nucleus, but are held in orbit due to the electrons' attraction to the oppositely charged protons in the nucleus.
Thomson's model, or the plum pudding model, it describes atoms as spheres of positively charged matter, in which electrons are embedded in.
The key difference is the locations of, and the motions of the electrons.
<h3>
Answer:</h3>
The conservation of mass and matter is true
<h3>
Explanation:</h3>
- The law of conservation of mass requires that the mass of reactants and products be equal in chemical reactions.
Given the equation;
AgNO₃ + HCI → AgCI + HNO₃
- The equation is balanced because, it has 1 silver atom, 1 nitrogen, 3 oxygen atoms, 1 hydrogen atom, and 1 chloride atom on both side of the equation.
- Therefore, the mass of the reactants and the products is equal which makes the law of conservation of mass hold.
- The conservation of matter is also true since the reaction process without changing the number of atoms of each element.
Answer:
Sodium + Water = Sodium Hydroxide + Dihydrogen
Explanation:
eaction of sodium with water
Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
