Answer:
RH = 20%
Explanation:
Data given:
water pressure at 0°C = 4.85 g/m³
Actual water vapor density = 0.97 g/m³
Relative humidity (RH) = ?
Solution:
Formula used
Relative humidity (RH) = 
x 100%
As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.
So,
put values in the above formula
Relative humidity (RH) = 0.97 g/m³ / 4.85 g/m³ x 100%
Relative humidity (RH) = 0.2 x 100%
Relative humidity (RH) = 20%
So,
Relative humidity (RH) = 20%
C₆H₄(COOH)(COOK) + CsOH = C₆H₄(COOCs)(COOK) + H₂O
C₆H₄(COOH)(COO)⁻ + K⁺ + Cs⁺ + OH⁻ = C₆H₄(COO)₂²⁻ + K⁺ + Cs⁺ + H₂O
C₆H₄(COOH)(COO)⁻ + OH⁻ = C₆H₄(COO)₂²⁻ + H₂O
It would have 11 valance electrons.
Example/Explanation:
Say we are talking about groups 10. Group 10 would have 10 valance electrons because of the atom's electronic arrangement in the periodic table.
Answer:
9g
Explanation:
moles O2 = mass / Mr = 12 / 2(16.0) = 0.375
ratio O2 : NO = 5:4
moles NO produced = 0.375 * 4/5 = 0.3
mass NO = Mr * mol = (14.0+16.0) * 0.3 = 9g
