On a warm summer day in Oslo, the temperature is 21 degree C and the relative humidity is 70%. What is the absolute humidity? Wh
lesya [120]

Explanation:

According to the psychrometric chart at dry bulb temperature of 21^{o}C and RH 70%, the absolute humidity = 0.011 kg/kg dry air

Formula to calculate humid volume is as follows.

       \nu_{H} m^{3}/kg dry air = \frac{22.41}{273}TK (\frac{1}{28.97} + \frac{1}{18.02}H)

                     = (2.83 \times 10^{-3} + 4.56 \times 10^{-3} H) T K

                     = (2.83 \times 10^{-3} + 4.56 \times 10^{-3} \times 0.011) \times 294

                       = 0.847 m^{3}/kg dry air

Hence, humid volume of air is 0.847 m^{3}/kg dry air.

Specific enthalpy of dry air  = specific heat capacity of dry air × dry bulb temperature

                    = 1.006 kJ/kg ^{o}C \times 21^{o}C

                    = 21.126 kJ/kg dry air

Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.

As per the psychrometric chart at given conditions wet bulb temperature = 17.5 ^{o}C

As per the psychrometric chart at given conditions dew point temperature = 15.5 ^{o}C

Balance the following chemical reaction: _NaOH + _H2SO4 ----->_Na2SO4 +_H20
Dima020 [189]

Answer:

Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water

2NaOH + H2SO4 → Na2SO4 + 2H2O

Explanation:

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.

Ionic charges are not yet supported and will be ignored.

Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.

Compound states [like (s) (aq) or (g)] are not required.

You can use parenthesis () or brackets [].

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
