Answer:
Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.
B. the process of diffusion.
c. a lower concentration of perfume particles the the other corners of the room.
D. a higher concentration of perfume particles the the other corners of the room.
-Column 2:
-Transition Metal Columns:
-Columns 3–7:
-Column 8:
Answer:
Column 1. They have one valence electron
Column 2. They have 2 valence electrons
Transition metal column. Variable oxidation states
Column 3–7. Valence electron ranges from 3 to 7 electrons
Column 8. Completely filled i.e no valence electron
Explanation:
Each column of the periodic table represents elements with a specific number of valence electrons. Columns 1 and 2 have one and two valence electrons respectively, and are known for their reactivity. Transition metals typically have one or two, Columns 3-7 have 3 to 7, and Noble Gases in Column 8 have a full shell of eight, making them unreactive.
We can categorize columns, or groups, of the periodic table by the number of valence electrons, which are the outermost electrons in an atom that participate in chemical bonding.

The answer is: B) Spills in your shop and any releases on pavement or outside should be poured down a drain.
Pouring used oil down a drain can cause damege to environment.
Oil is nonpolar substance and does not dissolve in the water (polar molecule), used oil remain existent in the drain and sewer or in the environment.
Small spills create a cumulative effect with significant impact on the environment.
Untended spills inside a shop can spread to an inside drain connected to the storm sewer system and cause floods.

Answer:
od
Explanation:
when burning a chemical compound the lighter element seperates from the stronger one
Answer: D) carbon dioxide + carbon - oxygen
Explanation: In the gas phase, carbon dioxide molecules undergo significant vibrational motions and do not keep a fixed structure. However, in a Coulomb explosion imaging experiment, an instantaneous image of the molecular structure can be deduced. Such an experiment has been performed for carbon dioxide. The result of this experiment, and the conclusion of theoretical calculations based on an ab initio potential energy surface of the molecule, is that none of the molecules in the gas phase are ever exactly linear. This counter-intuitive result is trivially due to the fact that the nuclear motion volume element vanishes for linear geometries. This is so for all molecules (except diatomics!).
