Answer:
you did not give the specific heat like formula like it takes 1kj to raise 28grams of water by 10 grams
Synthetic cathinone can be made in small amounts by creating a chemical reaction through the mixing of pseudoephedrine with regular household items.
<h3>What is cathinone?</h3>
Cathinone is an alkaloid drug obtained from a shrub plant (<em>Catha edulis</em>) and is equivalent to Akovaz (ephedrine).
The cathinone can also be artificially designed by using a pseudoephedrine medical drug.
Synthetic cathinone can be artificially produced in order to obtain this substance for medical use.

The (valence) electrons of an atom because they're the most moveable particles of the atom...they are found on the valence shells and can move, unlike the protons and neutrons which are enclosed in the nucleus of the atom.
Answer: The wire is still copper and does not change by cutting it
Explanation:
Democritus postulated that all materials were composed of these tiny particles called as "atomos".
Daltons postulates are:.
1. All matter is made of very tiny particles called atoms.
2. Atoms is indivisible.
3. Atoms of a given element are identical in mass and chemical properties.
4. Atoms of different elements have different masses and chemical properties.
5. Atoms combine in the ratio of small whole numbers to form compounds.
6. The relative number and kinds of atoms are constant in a given compound.
Thus when copper wire is cut into the smallest possible pieces, the atoms were intact as they are indivisible and all atoms have same mass and chemical properties.Thus the wire is still copper and does not change by cutting it
