Answer: Heat is removed as a gas turns into a liquid
Explanation:I took the test
Answer : K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
Explanation :
The relation between the equilibrium constant and standard Gibbs, free energy is:
where,
= standard Gibbs, free energy
R = gas constant
T = temperature
K = equilibrium constant
From the above relation we conclude that,
When K > 1 then the value of is negative.
When K < 1 then the value of is positive.
When K = 1 then the value of is zero.
When K = 0 then the value of is undefined.
Hence, K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
We can use the ideal gas law equation to solve for the number of moles present
PV = nRT
P - pressure - 107 kPa
V - 39.0 x 10⁻⁶ m³
n - number of moles
R - 8.314 Jmol⁻¹K⁻¹
T - temperature in K - 27 °C + 273 = 300 K
Substituting these values into the equation
107 000 Pa x 39.0 x 10⁻⁶ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 300 K
n = 1.67 x 10⁻³ mol
Answer:
acid +base gives salt and water
acid and carbon gives salt and water and carbon dioxide
acid and metal gives salt and hydrogen
To find the area of something you have to multiply the length x the with x the height. Or if it gives to the base then you multiply the base x the height.
