2 H2(g) + O2(g) → 2 H2O(g)
alexgriva [62]

Answer:

77 L of water can be made.

Explanation:

Molar mass of O_{2} = 32 g/mol

So, 55 g of O_{2} = \frac{55}{32} mol of  O_{2} = 1.72 mol of  O_{2}

As hydrogen is present in excess amount therefore  O_{2} is the limiting reagent.

According to balanced equation, 1 mol of  O_{2} produces 2 mol of H_{2}O.

So, 1.72 mol of O_{2} produce (2\times 1.72) mol of H_{2}O or 3.44 mol of H_{2}O.

Let's assume H_{2}O gas behaves ideally at STP.

Then, P_{H_{2}O}.V_{H_{2}O}=n_{H_{2}O}.R.T   , where P, V, n, R and T represents pressure, volume, no. of moles, gas constant and temperature in kelvin scale respectively.

At STP, pressure is 1 atm and T is 273 K.

Here, n_{H_{2}O} = 3.44 mol and R = 0.0821 L.atm/(mol.K)

So, (1atm)\times V_{H_{2}O}=(3.44mol)\times (0.0821L.atm.mol^{-1}.K^{-1})\times (273K)

  \Rightarrow  V_{H_{2}O}=77L

Option (b) is correct.

Name the following FBr. ?
gogolik [260]

Answer:

FBr is a chemical formula representing "flourine monobromide."

Explanation:

Of course, FBR could represent a number of things, from the Federal Board of Revenue to a fluidized bed reactor. I gave the answer I did because you listed this question as Chemisty.

Electrons in an atom cannot exist between energy levels
pishuonlain [190]
According to Bohr, the electrons in an atom were only allowed to exist at certain energy levels. ... Just as children cannot hover between two steps on a staircase, Bohr suggested that electrons cannot hover between two energy levels in the atom. Bohr developed his energy level model further using principles from physic

Consider the reaction cl2(g) + i2(g) <=> 2 icl(g), which is endothermic as written. what would be the effect on the equili
bogdanovich [222]

The given equilibrium reaction is,

Cl_{2}(g)+I_{2}(g)+Heat2ICl(g)

According to Le Chatelier's principle states that when a system in equilibrium is disturbed by varying conditions like concentration, pressure, and temperature of the system, the system tries to counter act the affect by shifting the equilibrium towards the required side.

When Cl_{2} is removed from the system, the concentration of chlorine (Cl_{2}) decreases, the equilibrium is disturbed. So, the system tries to re-establish the equilibrium by moving in that direction which produces more of chlorine, that is towards the reactant side.

The correct answer would be: 1. reaction would go to the left, making more "reactants"
