Answer:
Explanation:
Natural Rain:
"Normal" rainfall is slightly acidic because of the presence of dissolved carbonic acid. ... The gases of sulfur oxides and nitrogen oxides are chemically converted into sulfuric and nitric acids. The non-metal oxide gases react with water to produce acids (ammonia produces a base).Natural Rain:

well yah .... homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.
while on the other hand ...A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
there are many differences between these two .... but fr a basic info .... i guess what i said would help .....
Answer:
X axis shows the independent and Y axis shows the dependent.
Explanation:
- As the independent variable is always plotted on the X-axis of the graph the Y-axis shows the dependent variable that is affected by the X variables Time is an independent variable and is always shown along the X-axis.
- Such as the image showed tells about the data of N2O biofuel emissions from 2009-10. Thus this will be plotted along the X-axis and Y-axis will show the amount of nitrogen fertilizer applied.
Technetium, with atomic number (denoted Z) 43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive. The second-lightest exclusively radioactive element, promethium, has an atomic number of 61.
Equal volumes of equal concentrations of strong acid and strong base are mixed. Because the volumes and molarities are equal, the number of mole NaOH and HCl are equal.
From reaction
HCl + NaOH ---> NaCl +H2O
we can see that if number of moles HCl and NaOH are equal, they will react completely, and no acid or base is going to be in solution anymore.
So, pH=7.
