Answer:

There results pointed out that it was possible for organic molecules to be produced  under some reducing conditions which are similar to the primitive earth.Specifically they deduced that volcanic eruption occurring  simultaneously with the lightning may have been responsible for the production of large quantities of some biological molecules on the early earth.

However, objection was raised to the claim that, NH3 and CH4 used in the experiment were the most  abundant gases of  primitive earth.  Inert Nitrogen and Carbon were the  prevalent gases of the early earth,nullifying  the authentication of the experiment.Thus their experiment was wrong.

Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) Wha
lana66690 [7]

Answer: 21850.42mmHg or 28.78atm

Explanation: From the equation of the reaction, 2 moles of sodium reacts with 2 moles of water to produce 2 moles of NaoH and 1 mole of hydrogen gas at s.t.p.

molar volume of gas at s.t.p. = 22.4dm^3,

standard temperature = 0°C or 273K,

standard pressure = 760mmHg or 1atm,

molar mass of Na = 23g;

volume of the container= 20L or 20dm^3

From the equation, 2 moles or 46g of Na produces i mole or 22.4 dm^3 of hydrogen.

Therefore, 1kg or 1000g of Na will produce 22.4 * 1000/(46)= 486dm^3 of hydrogen.

To find the pressure of the gas produced, the formula P1V1/T1 = P2V2/T2

P1= 760mmHg, T1= 273K, V1 (initial volume of gas)= 486dm^3, T2=50.0°C or 50+273K= 323K, V2( final volume of gas= volume of vessel)=20dm^3  P2=?

P1= P1V1*T2/(V2T1)= 760mmHg * 323/(273)= 21850.42mmHg or 1atm*21850.42/760= 28.78atm
