Anhydrous  is  the  compound  that  is  completely  dry or  it  is  water  free.example  sodium  sulfate is  referred  to  as anhydrous   sodium  sulfate  when it  is  free  from water. The  anhydrous compound  are used  as a drying  material since  without  water  bonded  to  its  molecules salt  will  usually  absorb  moisture  it come  into  contact  with  and therefore  it  is used  as  a  dehydrating  substance.

After the end of a normal inspiration, the volume of air in the lungs is about 2.8 L. Normally quiet inspiration is driven by a
vodka [1.7K]

Answer:

The Volume of the lungs that would produce 2 mmHg pressure decrease is

         V_2 = 2.81 \ L

Explanation:

From the question we are told that

     The volume of air in the lungs is  V = 2.8 \ L

     The pressure difference for quit normal inspiration is P = 2 \ mmHg

      The temperature of air in the lungs T = 37^oC

      The pressure  after normal  expiration is at  T =  760 \ mmHg

     

From ideal gas law we have that

         PV= nRT

Now since  nRT is constant we have that

        P_1 V_1 = P_2 V_2

As the pressure decreased by 2 mmHg the volume becomes

        V_2 = \frac{P_1 V_1}{P_2}

        V_2 = \frac{2.8 * 760}{758}

        V_2 = 2.81 \ L

Laughing gas, N2O, also known as nitrous oxide contains 28.01 g of nitrogen in every 44.01 g of nitrous oxide. What mass of nitr
Sav [38]

Answer : The mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.

Explanation :

As we are given that, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide. Now we have to determine the mass of nitrous oxide formed from 85.20 g of nitrogen.

As, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide

So, 85.20 g of nitrogen is present in \frac{85.20}{28.01}\times 44.01=133.9g of nitrous oxide

Thus, the mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.
