Answer is: can dissolve in water.
Magnesium oxide (MgO):
1) does not have molecular structure.
2) it is not higly reactive, it is physically and chemically stable at high temperatures.
3) has very high boiling point (around 3600°C), because strong ionic bond between magnesium cations (Mg²⁺) and oxygen anion (O²⁻).
4) dissolve in water, because it has ionic bond.
Hydrogen peroxide (H₂O₂):
1) have molecular structure.
2) it is higly reactive, it is not physically and chemically stable.
3) has low boiling point (around 150°C), because weakcovalent bonds.
4) dissolve in water, because it has polar bond.
Answer:
simple chemistry experiment—adding baking soda to vinegar—seems to challenge the law of conservation of mass.
Answer:
nine
There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals. The five different orientations of orbitals in the 3d subshell are shown in the figure below.
Explanation:
Answer:
All living things are made up of cells.
cells are the basic unit of structure and function of ll living things.
All cells are come from other cells.
Explanation:
The cell theory is historic scientific theory and is universally accepted. This theory was given by Robert Hook in 1665. According to this theory all living things are made up cells.
Cell:
Cell is the smallest unit of life and it is building block of life.
This theory consist of following points:
All living things are made up of cells.
Cells are the basic unit of structure and function of ll living things.
All cells are come from other cells. Which means that cells are originated from pre-existing cells.
The other given options:
Cells comes from nonliving matter.
Cells make up most organisms bu not all.
These are two are not the postulate of cell theory because all living organisms are made of cells.
