Atoms like in chemistry class?
Answer:
C
Explanation:
This is the only option that could produce an objective answer through experimentation or studies. The other options can be answered subjectively and are opinion based. They could not be answered scientifically.
The first organisms are autotrophs (primary producers)
The ones that form in tropical weather.
Answer:
The equilibrium constant for this reaction is 3.2
Explanation:
Step 1: Data given
Number of moles H2S = 1.0 moles
Number of moles H2 = 4.0 moles
Number of moles S2 = 0.80 moles
Volume = 4.0 L
Step 2: The balanced equation
2H2S(g) ⇆ 2H2(g) S2(g)
Step 3: Calculate molarity
[H2] = 4.0 moles / 4.0 L = 1.0 M
[S2]= 0.80 moles / 4.0 L = 0.20 M
[H2S] = 1.0 moles / 4.0 L = 0.25 M
Step 4: Calculate Kc
Kc = [H2]²[S2] / [H2S]²
Kc = (1.0²*0.20)/0.25²
Kc = 0.2 / 0.0625
kC = 3.2
The equilibrium constant for this reaction is 3.2
