Your closes answer would be a.10
I believe the criteria responsible for deciding whether a heterogeneous mixture is a colloid or a suspension is whether the <span>particles remain suspended for an extended period of time. I hope it helps you.</span>
Answer:
Theoretical yield for CO₂ is 5.10g
Explanation:
Reaction: 2C₆H₆(l) + 15O₂(g) → 12CO₂(g) + 6H₂O(g)
We convert the mass of oxygen to moles:
4.64 g /32 g/mol = 0.145 moles of O₂
Let's find out the 100% yield reaction of CO₂ (theoretical yield)
Ratio is 15:12. So let's make this rule of three:
15 moles of O₂ can produce 12 moles of CO₂
Therefore 0.145 moles of oxygen will produce (0.145 . 12) /15 = 0.116 moles
We convert the moles to mass: 0.116 mol . 44 g / 1mol = 5.10 g
Answer:
Blue, orange and green
Explanation:
Three different colors are observed from compounds containing different oxidation states of chromium: +2 (blue), +3 (green), and +6 (orange).
Answer:
The solid will sublime into a gas
Explanation:
In the graph in the attachment
Y-axis represents pressure in mm of Hg
X- axis represents temperature in degree Celsius
The graph show the triple point of water.
Clearly, the sample will go from solid to vapor directly, no liquid involved (pink line is there to show that this is below triple point)
So
expect sublimation
The solid will sublime into a gas.
