Answer: <em>Newton's first law</em>
Explanation: <em>The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>

No, you cannot.
The distinction is made in the fact that the sodium and chlorine atoms are bonded chemically, while the crushing of the salt is a physical change. A physical change is one that does not have the ability to change the identity of the substance. Such changes include crushing, boiling, melting. In order to separate the chlorine and sodium atoms, you must make them undergo a chemical change, for example add the salt to sulfuric acid and make it react.
Well do you have any answer choices and organic is mostly living so whatever answer that is a living thing like plants, animals, humans etc.
Answer:
1. The combined number of protons and neutrons remains constant.
2. There are two atoms with mass numbers of 2.
3. It is the number of protons plus neutrons.
4. A nucleus with a greater mass than any of the reactants will be produced.
5. Fusion reactions in the sun convert small amounts of matter into large amounts of energy.
Answer:
0.05 M.
Explanation:
For the concentrated sulphuric acid,
Number of moles = molar concentration × volume
= 0.1 × 0.1
= 0.01 mol
New volume = 100 + 100 ml
= 200 ml
Concentration of the diluted sulphuric acid = number of moles/volume
= 0.01/0.200
= 0.05 M
