Answer: Chemical bonds form when two or more molcules interact with eachother.
Explanation:
Mass is the amount of matter an object has. We often use a triple-balance beam to measure mass. A triple-beam balance gets its name because it has three beams that allow you to move known masses along the beam. Here is a picture of a triple beam balance.
Answer:
The answer to your question is given below
Explanation:
The balanced equation for the reaction is given below:
CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)
1. Writing an expression for the equilibrium constant, K.
The equilibrium constant, K for a reaction is simply the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.
Thus, we can write the equilibrium constant, K for the reaction as follow:
CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)
K = [CaCO3] [H2]⁴ / [CaO] [CH4] [H2O]²
2. Based on the value of K, more products will be in the equilibrium mixture since the value of K is a positive large number.
Data Given:
Change in Entropy = ΔH = 120.5 kJ = 1.20 × 10⁵ J
Temperature = T = 298 K
Change in Entropy = ΔS = 758.2 J/K
Using Formula,
ΔG = ΔH - T ΔS
Putting Values,
ΔG = (1.20 × 10⁵ J) - (298 K × 758.2 J/K)
ΔG = -1.059 × 10⁵ J
ΔG = -105.94 kJ
