Gaseous ammonia chemically reacts with oxygen O2 gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ox
WINSTONCH [101]

Answer : The number of moles of oxygen needed are, 1.5 moles.

Explanation :

The balanced chemical reaction will be:

4NH_3+5O_2\rightarrow 4NO+6H_2O

Now we have to calculate the moles of oxygen.

From the balanced chemical reaction we conclude that,

As, 6 moles of water vapor produces from 5 moles of oxygen

So, 1.80 moles of water vapor produces from \frac{5}{6}\times 1.80=1.5 moles of oxygen

Therefore, the number of moles of oxygen needed are, 1.5 moles.

Calculate the molecular formula of a compound with the empirical formula C5H11 and a molar mass of 142.32 grams/mole
MA_775_DIABLO [31]
Relative formula mass C₅H₁₁ = 71

Now divide the molar mass by the RFM = 142.32 / 71 = 2

Now C₍₅ₓ₂₎H₍₁₁ₓ₂) = C₁₀H₂₂

Hope that helps

What is the reason behind that the melting and boiling point of iron is more than that of sodium?​
sweet [91]

Answer:

As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
