</span> By this you only get about 70% alcohol 30% water
As they are <span>azeotropes and cannot be distilled further
so correct option is B
hope it helps

Answer:A.Preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.
Explanation: when ultraviolet solar radiation penetrates into the Earth's atomosphere and heats it,
the conventional radiation is supposed to be radiated back into the atmosphere as heat.however this is prevented from happening due to green house gases,they absorb the radiant heat and retain this heat within the Earth's environment and so behaves like the glass barrier in green houses.these green house gases trap heat within the Earth causing global warming .
Answer:
6 molecules of H2O are the maximum number.
Explanation:
From the drawing it can be seen that there are 6 H2 molecules and 3 O2 molecules reacting, which can be represented by the following chemical equation
6 H2 + 3 O2 ⇒ H2O
This equation is not balanced, so we proceed to balance it, being as follows:
6 H2 + 3 O2 ⇒ 6H2O
With which it can be determined that a maximum of 6 H2O molecules can be formed.
1cm^3 = 1L would be the correct answer. One cubic centimeter equals .001 liter, so this equality above is not correct.
Please let me know if you have any questions! :)
