It is 50. This is because heat goes from higher temperatures to lower and nothing else in the options is lower.
Answer:
False.
Explanation:
1. Most liquids do not have ionized atoms or particles within them, as the state of matter does not really allow that to freely happen.
2. Liquids may not have a definite shape, however, they have a definite volume. No matter the container you pour them into, their volume remains constant.
3. Liquids are not good conductors of electricity. Take for example water. Pure water does not conduct electricity
Hence, the statement is false with regards to liquids. However, it is true when talking about the foruth state of matter - Plasma
Carbon dioxide and ATP are produced.
Answer:
Mol. mass of ethyl alcohol =C2H5OH=46
No. of moles of ethyl alcohol =4660=1.304
Mol. mass of methyl alcohol =CH3OH=32
No. of moles of methyl alcohol =3240=1.25
′XA′, mole fraction of ethyl alcohol =1.304+1.251.304=0.5107
′XB′, mole fraction of methyl alcohol =1.304+1.251.25=0.4893
Partial pressure ethyl alcohol =XAp˙A0=0.5107×44.5=22.73mmHg
Partial pressure methyl alcohol =XBp˙B0=0.4893×88.7=73.40mmHg
Total vapour pressure of solution =22.73+43.40=66.13mmHg
Mole fraction of methyl alcohol in the vapour
=Total vapour pressurePartial pressure of CH3OH
