Answer:

<u>D</u>

Explanation:

Mercury is Hg.  Most of these reaction do not involve Hg.  Only D correctly shows a balanced equation with mercury (Hg).

(A) Pro(s)-> Pr(s) + O(g)                                  

(B) Mc₂O(s)-> 2 Mc(s) + O(g)

(C) 2 MnO(s)-> 2 Mn(s) + 20(g)

(D) 2 HgO(s)-> 2 Hg(1) + O₂(8)

A 3.00-L flask is filled with gaseous ammonia, NH3. The gas pressure measured at 27.0 ∘C is 2.55 atm . Assuming ideal gas behavi
Whitepunk [10]

Answer : The mass of ammonia present in the flask in three significant figures are, 5.28 grams.

Solution :

Using ideal gas equation,

PV=nRT\\\\PV=\frac{w}{M}\times RT

where,

n = number of moles of gas

w = mass of ammonia gas  = ?

P = pressure of the ammonia gas = 2.55 atm

T = temperature of the ammonia gas = 27^oC=273+27=300K

M = molar mass of ammonia gas = 17 g/mole

R = gas constant = 0.0821 L.atm/mole.K

V = volume of ammonia gas = 3.00 L

Now put all the given values in the above equation, we get the mass of ammonia gas.

(2.55atm)\times (3.00L)=\frac{w}{17g/mole}\times (0.0821L.atm/mole.K)\times (300K)

w=5.28g

Therefore, the mass of ammonia present in the flask in three significant figures are, 5.28 grams.
