Answer:
Solid to liquid
Explanation:
Entropy is a state of randomness or disorderliness of the particles of a system. Some part of the heat energy of a system is related to the state of disorder or randomness of the particles of the system.
The entropic level of a system depends on two of major factors:
1. Temperature: Entropy increases with temperature rise due to the fact that the randomness of the particles of a system increases at a higher temperature.
2. Physical state of matter: The increasing order of entropy is:
Solid < Liquid < Gas
Gases are the most disordered and have the highest entropy. In moving from solid to liquid to gas, entropy of a system would increase.
Barium Cynanide is the compound
The elements in the periodic table are arranged in columns - elements in the same column exhibit similar properties.
Mg and Sr are in the same column (period I)
Br and F (period XVII - 17)
S and O (period XVI - 16)
Answer:
32.8 C
Explanation:
- Use combined gas law formula and rearrange.

Aluminum ions have a charge of +3. This means that the atoms have three more protons than electrons. In order to add electrons to aluminum ions, the purification process therefore requires a large amount of electricity.
Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals
ion
atom that has a positive or negative charge because it lost or gained one or more electrons
chemical bond
the attractive force that holds atoms or ions together
ionic bond
a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions
chemical formula
a combination of chemical symbols and numbers to represent a substance
covalent bond
bond formed by the sharing of electrons between atoms
