Which compound is produced when HCl(aq) is neutralized by Ca(OH)2(aq)?
kiruha [24]

<u>Answer:</u> The correct answer is Option 1.

<u>Explanation:</u>

Neutralization reaction is defined as the reaction in which acid reacts with a base to produce a salt along with water.

Here, HCl is an acid and Ca(OH)_2 is a base. When these two compounds react, the salt obtained is calcium chloride.

The equation for the above reaction is given by:

2HCl(aq.)+Ca(OH)_2(aq.)\rightarrow CaCl_2(s)+2H_2O(l)

Hence, the correct answer is Option 1.

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is ________ M sodium ion and ________ M sulfate i
omeli [17]

Answer:

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion.  (option E)

Explanation:

Step 1: Data given

Volume = 500 mL = 0.500 L

The concentration sodium sulfate = 2.104 M

Step 2: The equation

Na2SO4 → 2Na+ + SO4^2-

For 1 mol Na2SO4 we have 2 moles sodium ion (Na+) and 1 mol sulfate ion (SO4^2-)

Step 3: Calculate the concentration of the ions

[Na+] = 2*2.104 M = 4.208 M

[SO4^2-] = 1*2.104 M = 2.104 M

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion.  (option E)

Explain how temperature and precipitation are affected by latitude and the sun's rays.
Contact [7]
Latitude and Temperature

At the equator, the Sun's rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun's rays are less direct. The farther an area is from the equator, the lower its temperature.
