দুইটি এনানসিওমারের সমতুল মিশ্রণকে (equimolar mixture of two enantiomers) কী বলে?

সঠিক উত্তর: রেসিমিক মিশ্রণ (racemic mixture)

দুইটি এনানসিওমারের সমতুল মিশ্রনকে কী বলে?

In a gas mixture of hydrogen and oxygen, steady state equimolar counter diffusion is occurring at a total pressure of 100 kPa and temperature of 20°C. If the partial pressures of oxygen at two planes 0.01 m apart, and perpendicular to the direction of diffusion are 15 kPa and 5 kPa, respectively and the mass diffusion flux of oxygen in the mixture is 1.6 * 10–5 kmol/m2.sec, calculate the molecular diffusivity for the system. For equimolar counter current diffusion:

সমান ধারকত্বের 3টি ধারকের সমান্তরাল সমবায়ের সমতুল ধারকত্ব তাদের শ্রেণী সমবায়ের সমতুল ধারকত্বের কত গুণ?

In a mixture, water and milk are in the ratio of 3 : 5. In the second mixture, the ratio of water and milk is 9 : 11. If these two mixtures be mixed to form anew mixture in which water and milk are in ratio 5 : 7, then what is the ratio of these two mixtures in the new mixture?

The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. The temperature at which the above mixture will exert a pressure of one standard atm. is

A mixture contains 2/5 of element A and 3/5 of element B. When 5ml of A is added to the mixture, the proportion of B in the mixture changes to 1/5. What amount of A was originally present in the mixture before the addition was made ?

A jar contains a mixture of oil and water in the ratio 22 :3 . 50 litres of the mixture was taken out and 25 litres of water was added to it. If water was 34% in the resultant mixture, what was the initial quantity of the mixture (in litres ) in the jar?

A mixture containing 45% of oil is mixed with another mixture containing x% of oil in a ratio 3 : 5. If the quantity of oil in the final mixture is 50% of the mixture, find the value of x.

In a mixture of milk and water, there is only 26% water. After replacing the mixture with 7 liters of pure milk , the percentage of milk in the mixture become 76%. The quantity of mixture is:

A mixture is composed of 11 parts of pure milk and 2 parts of water. If 35 litres of water were added to the mixture then the new mixture will contain twiceas much pure milk as water, then how many litres of pure milk does the original mixture contain?
