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

Brums [2.3K]
The statement above is FALSE.
When a particular specie in an ecosystem is endangered, other species that interact with it will be negatively affected and the ecosystem may be throw out of balance. This is because all the components of the ecosystem depend on one another for survival.
