The human activity that impacts the weather on Earth negatively is the burning of fossil fuels. When burning the fossil fuels, the temperature on Earth is increased. This causes Greenhouse Gases. The EPA is trying to cut down on the burning of fossil fuels by closing down power plants ran off of coal.
<u>Answer:</u> The net ionic equation contains 
ions
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of ammonium sulfate and calcium nitrate is given as:
Ionic form of the above equation follows:
As, ammonia and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation contains ions
Answer:
0.2M NaOh
Explanation:
there are 0.2 mol of NaOH in 8.0 g. (8.0/40) =0.2. Molarity = mol/L = 0.2M.
On the second shell there are two individual subshells:
The "s" subshell has only 1 orbital with max. two electrons spinning around; and the so-called "p" subshell has 3 orbitals with max. 6 electrons (2 on each!)
In total, there are four orbitals with 8 revolving electrons on the second shell.
Hope could help :)
Answer:
Endocrine disruptor
Explanation:
This means that the four substances, even they are used in different areas like gardening, plastics or pots, all of them change the endocrine system in humans because they imitate the natural hormones and the body stops to produce them or starts to produce more hormones than the body needs.
They are correlate with some illness like cancer, thyroid problems and infertility.
