Answer: D) Monitor the sea level over set period of time.
Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.
Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.
This is because the relative atomic mass is the sum of the no of protons and neutrons while the atomic no is of the former only. it is not a whole number it is th average weighted masses of the various isotopes of the element multiplied by their corresponding relative abundance. pls thank me and mark me briniest
Answer:
Option a (100 kPa) is the appropriate option.
Explanation:
The given value is:
Original pressure,
P₁ = 50 kPa
Let the new pressure be "x".
Now,
⇒ 
On substituting the values, we get
⇒ 
On applying cross-multiplication, we get
⇒ 
⇒ 
Thus the answer above is the right one.
Answer:
![[NH_2NO_2]=0.0868M](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D0.0868M)
Explanation:
Hello,
In this case, for the given chemical reaction, the first-order rate law is:
![r=\frac{d[NH_2NO_2]}{dt} =-k[NH_2NO_2]](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%5BNH_2NO_2%5D%7D%7Bdt%7D%20%3D-k%5BNH_2NO_2%5D)
Which integrated is:
![[NH_2NO_2]=[NH_2NO_2]_0exp(-kt)](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D%5BNH_2NO_2%5D_0exp%28-kt%29)
Thus, the concentration after 31642.0 s for a 0.384-M solution is:
![[NH_2NO_2]=0.384M*exp(-4.70x10^{-5}s^{-1}*31642.0s)\\](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D0.384M%2Aexp%28-4.70x10%5E%7B-5%7Ds%5E%7B-1%7D%2A31642.0s%29%5C%5C)
![[NH_2NO_2]=0.0868M](https://tex.z-dn.net/?f=%5BNH_2NO_2%5D%3D0.0868M)
Best regards.
Answer:
- c. <em>Aqueous solutions of hydrochloric acid and potassium hydroxide react to produce aqueous potassium chloride and water.</em>
Explanation:
The reaction is represented by the chemical equation
- HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)
The letters "aq" in parenthesis, next to the chemical formula of a compound, is used to indicate "aqueous" phase. It means that the compound is dissolved in water or, what is the same, it is an aqueous solution.
Hence, the choice C. is the best representation or description of the given reaction:
The <u>left side</u> or reactant side is:
HCl(aq) + KOH(aq)
↑ ↑ ↑
<em>aqueous solution of react aqueous solution of </em>
<em>hydrochloric acid with potassium hydroxide </em>
The <u>right side</u> or product side is:
KCl(aq) + H₂O(l)
↑ ↑ ↑
<em>aqueous and water</em>
<em>potassium chloride </em>
