Calculate the number of grams of aluminum chloride and water formed when 0.500 g of aluminum hydroxide react with stomach acid.

Answer : The mass of and produced will be, 0.852 and 0.346 grams respectively.

Explanation : Given,

Mass of = 0.500 g

Molar mass of = 78 g/mole

Molar mass of = 133 g/mole

Molar mass of = 18 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of and .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of react to give 1 mole of

So, 0.00641 mole of react to give 0.00641 mole of

And,

As, 1 mole of react to give 3 mole of

So, 0.00641 mole of react to give mole of

Now we have to calculate the mass of and .

and,

Therefore, the mass of and produced will be, 0.852 and 0.346 grams respectively.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
