Answer:
Explanation:
Raoult's law is a tool that allows to determine vapour pressure of solutions. The formula is:
<em>(1)</em>
Where
P is Pressure of solution and solvent and X is mole fraction.
Moles of solute and solvent are:
Biphenyl:
11.5g×(1mol /154.21g) = <em>0.0746mol</em>
Benzene
31.9g×(1mol /78.11g) = <em>0.408mol</em>
Mole fraction of benzene is:
= <em>0.846</em>
Replacing in (1):

Answer:
I think it's 1
Explanation:
As the balloon rises the gas inside the balloon expands because the pressure surounding the balloon drops.
Reduces from birth till old age is the answer because if you look at the chart, you can see that both the percentages and hours of total sleep time decrease as humans get older.
Answer:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
We are to give the reaction expression for this displacement reaction.
Reactants = copper and silver nitrate solution
Products = silver and copper (II) nitrate
Copper = Cu
Silver nitrate solution = AgNO₃
Silver = Ag
copper (II) nitrate = Cu(NO₃) ₂
So:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
Mitosis and Meiosis are forms of cell division. They use the same steps for cell division which are Prophase, Metaphase, Anaphase and Telophase.
Mitosis produces 2 diploid cells while Meiosis produces 4 haploid cells.
Meiosis stages -
- Interphase
- Prophase I
- Metaphase I
- Anaphase I
- Telophase I
- Prophase II
- Metaphase II
- Anaphase II
- Telophase II
- Cytokineses
Mitosis stages
- Prophase
- Prometaphase
- Metaphase
- Telophase
