Answer:
Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. ... A third, much smaller contributor to sea level rise is a decline in the amount of liquid water on land—aquifers, lakes and reservoirs, rivers, soil moisture.

I belive it is the range hope it helped! :)
Explanation:
PH = -log [H⁺] ←←[log without a specified base means log base 10]
<span>and if you want to use the hydronium ion concentration then use pH = -log [H₃O⁺] </span>
<span>either way the calculation is the same: </span>
<span>They give that a 0.1 M solution of NaHCO₃ has a hydrogen ion concentration of 4.0 x 10^(-9) </span>
<span>so pH = -log (4.0 x 10^(-9)) </span>
<span>pH = 8.4</span>
<span>The only thing that could explain why this is is that each molecule of water is made with 2 atoms of hydrogen, and one atom of oxygen.</span>
Answer: 1. The ratio of the reactant aluminum to the product aluminum sulphate is 2:1
2. Option D. 1,3,2,2
Explanation: 1. From the balanced equation:
2Al + 3H2SO4 -> Al2(SO4)3 + 3H2
2moles of Al produced 1mole of Al2(SO4)3. Therefore, the ratio will be 2:1
2. C2H4 + 3O2 ---> 2CO2 + 2H2O from the equation, the coefficients are 1,3,2,2
