Answer:
10.54 L
Explanation:
Given that:-
Moles of = 1.00 moles
According to the given reaction:-
7 moles of oxygen gas reacts with 4 moles of ammonia
1 mole of oxygen gas reacts with moles of ammonia
Moles of ammonia = 0.5714 moles
Also, Given that:
Temperature = 850 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (850 + 273.15) K = 1123.15 K
n = 0.5714 moles
P = 5.00 atm
Using ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L atm/ K mol
Applying the equation as:
5.00 atm × V = 0.5714 moles ×0.0821 L atm/ K mol × 1123.15 K
⇒V = 10.54 L
<u>10.54 L of required.</u>
Answer:
the number of protons in the nucleus that are found in an atom is what determines an element's atomic number.why you may ask and thats because Protons contribute to the mass of an atom.(along with neutrons but they dont have a charge)but protons provide a positive charge to the nucleus.
Explanation:
because the atom is electrically neutral, the number of electrons must equal the number of protons.
