Answer:
A
B
C
Explanation:
A B and C are heterogeneous because they don’t have all the same components throughout. D is homogeneous because kool aid dissolves into the water.
Answer:
224 grams of O₂
Explanation:
This is the reaction:
2 C₂H₆ (g) + 7 O₂(g) → 4 CO₂ (g) + 6 H₂O (g)
2 moles of ethene react with 7 moles of oxygen.
Let's convert the ethene's mass into moles (mass / molar mass)
60 g / 30 g/m = 2 mol
So, if 2 moles of ethene must react with 7 moles of O₂ and we have 2 moles, obviously we would need 7 moles of oyxgen.
Let's convert the moles to mass ( mol . molar mass)
7 m . 32 g/m = 224 grams
So if you’re looking at a graph, the favored rxn is forward if product amount is higher at equilibrium, or the reverse rxn is favored if the reactant amount is higher at equilibrium.
You can tell through looking at the K value by seeing if it’s a large number, product is favored which means the forward rxn is favored, but if it’s smaller that means he reactant is favored, meaning the reverse rxn is favored.
