How quickly can the light struck reaction occur when unprotected beer is exposed to the proper wavelength of light?
OleMash [197]

Answer:

If the beer is in the crystal clear glass, unprotected from the sunlight then it will starts skunking within 30 seconds. The reason behind the skunking of the beer is a photo chemical reaction. So one can avoid the skunking of beer by packaging it in the cans or opaque bottles.

A 3.20 g sample of a salt dissolves in 9.10 g of water to give a saturated solution at 25°C. a. What is the solubility (in g sal
muminat

Answer:

  • The solubility of the salt is 35.16 (g/100 g of water).
  • It would take 71.09 grams of water to dissolve 25 grams of salt.
  • The percentage of salt that dissolves is 52.7 %

Explanation:

<h3>a.</h3>

We know that 3.20 grams of salt in 9.10 grams of water gives us a saturated solution at 25°C. To find how many grams of salt will gives us a saturated solution in 100 grams of water at the same temperature, we can use the rule of three.

\frac{3.20 \g \ salt}{9.10 \ g \ water} = \frac{x \ g \ salt}{100 \ g \ water}

Working it a little this gives us :

x = 100 \ g \ water * \frac{3.20 \g \ salt}{9.10 \ g \ water}

x = 35.16 \ g \ salt

So, the solubility of the salt is 35.16 (g/100 g of water).

<h3>b.</h3>

Using the rule of three, we got:

\frac{3.20 \g \ salt}{9.10 \ g \ water} = \frac{25 \ g \ salt}{x \ g \ water}

Working it a little this gives us :

x = \frac{25 \ g \ salt}{ \frac{3.20 \g \ salt}{9.10 \ g \ water}}

x = 71.09 g \ water

So, it would take 71.09 grams of water to dissolve 25 grams of salt.

<h3>C.</h3>

Using the rule of three, we got that for 15.0 grams of water the salt dissolved will be:

\frac{3.20 \g \ salt}{9.10 \ g \ water} = \frac{x \ g \ salt}{15.0 \ g \ water}

Working it a little this gives us :

x = 15.0 \ g \ water * \frac{3.20 \g \ salt}{9.10 \ g \ water}

x = 5.27\ g \ salt

This is the salt dissolved

The percentage of salt dissolved is:

percentage \ salt \ dissolved = 100 \% * \frac{g \ salt \ dissolved}{g \ salt}

percentage \ salt \ dissolved = 100 \% * \frac{ 5.27\ g \ salt }{ 10.0 \ g \ salt}

percentage \ salt \ dissolved = 52.7 \%

Yor older sister drove 500 miles to college one way in ten hours. what is her average velocity?
Lubov Fominskaja [6]
Average velocity is calculated as the division of displacement and change in time so the answer would be 804 km/36000 s=0.02 m/s
