I think the awnser would be C. becuase Pure Substances are made of mostly the same material and properties Such as: Nitrogen Gas, Oxygen Gas, Carbon, Iorn, Water, Sugar and Salt.
Answer:
Explanation:
The first thing to have in mind is that the Ksp (constant of solubility) gives you an idea of how much soluble a salt is. <u>If the concentration of ions of that salt exceeds the kps, the salt will precipitate</u>.
The Kps of all these salts are very small compared to the 0.1 M concentration of the anions so all of them will precipitate.
The smaller the constant, the faster the salt precipitates
Having that concept in mind, the order of precipitation from first to last would be:
Answer:
12 moles of F₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
N₂ + 3F₂ —> 2NF₃
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e
Xmol of F₂ = (3 × 8)/2
Xmol of F₂ = 12 moles
Thus, 12 moles of F₂ is needed for the reaction.
36.0 g of glucose divided by 180 g/mol = 0.200 moles of glucose
find molarity
0.200 moles of glucose / 2 liters = 0.100 molar solution
(hope this helps)
I would say the answer is photosynthesis
Hope this helps
