Answer:
If you have the time you can take it to a Waste Management Facility.
Explanation:
Because these unhardened glues are flammable, do not dispose of them in the trash or down the drain. Keep them away from open flames. If the glue is water-based, solidify it and throw it in the trash.
Answer:
An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.
ate = one more O than -ite
Explanation:
Example:
NO2 is nitrite
NO3 is nitrate
You can see that the molecules are made of the same elements, however they have more or less of one of the elements (i.e. oxygen).
Answer:
12, basic, 9, basic
Explanation:
pH = -log[H+]
Using the data in the table, you can calculate the pH:
-log[1e-12] = 12
-log[1e-9] = 9
To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.
Answer:
b) Both p orbitals are perpendicular to the F−Be−F bond axes.
Explanation:
Be has 2 electrons in its valence shell, subshell s is fulfilled, so it has no unpaired electrons in its ground state to make bonds with F. So, it can promote the electrons to the 2p orbital and will having sp hybridization.
The bond between the orbitals sp and the p orbital of F are in opposite directions but the same ax. The two bonds are equivalent, and the molecule had a linear geometry. The two unhybridized p orbitals on Be are vacant, and so they are perpendicular to the F-Be-F bond axes.
So basically Positive reinforcement is when you give someone something for showing a good behavior, and a negative reinforcement is giving someone a consequence for showing bad behavior.
Hope this helps:)
