If a sample o water is mixed with a surfactant, the most likely result is that the viscosity of the water will increase. This is because of the property of the surfactant which is generally viscous; and becomes more viscous when mixed with water.
Answer:
K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]
Explanation:
Based on the reactions:
CH2 (g) + H2O(g) ⇄ CO (g) + 3H2 (g) K1
CO (g) + H2O (g) ⇄ CO2 (g)+H2(g) K2
The sum of both reactions is:
CH4 (g)+2H2O (g) ⇄ CO2(g)+4H2(g) And K of the reaction is: K = K1×K2
K is defined as the ratio between concentrations of products and reactans. Each compound must be elevated to its coefficient in the reaction. That is:
<h3>K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]</h3>
Answer:
D.atom 2 is not the same , because the mass number is different from atoms 1 and 2
In chemistry, the letter "H" represents the enthalpy of a system. Enthalpy refers to the sum of the internal energy of a system plus the product of the system's pressure and volume. The delta symbol is used to represent change. Therefore, delta H represents the change in enthalpy of a system in a reaction.
