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.

Answer:

-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.

Explanation:

-Sodium Chloride has positively charged sodium ions, $Na^+$ and negatively charged chloride ions, $Cl^-$ .

-Water on the other hand has positively charged Hydrogen ions, $H^+$ and negatively charged Oxygen ions, $O^{2-}$ due to the difference in electroneganivity.

-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:

$NaCl+H_2O->NaOH+HCL\\\\Na^++Cl^-+H_2O->Na^++(OH)^-+H^++Cl^-$

A chemist prepares a solution by dissolving 0.3 mole of CaCl2 in enough water to make 1000 mL of solution. What is the molar con

Rasek [7]

$CaCl_{2}$ dissolves in water to give $Ca^{2+}$ and $Cl^{-}$ ions according to the following reaction:

$CaCl_{2}$ --------> $Ca^{2+}$ + 2 $Cl^{-}$

So, according to the above reaction, 1 mole of $CaCl_{2}$ produce 2 moles of $Cl^{-}$ ion,

So, 0.3 mole will give = 0.3 x 2 = 0.6 moles of $Cl^{-}$ ion

So, Molar concentration = $\frac{0.6moles}{1L} = 0.6$

Note: 1L = 1000mL
