How many moles of phosphine (PH3) are produced for every 4.0 moles of hydrogen that react according to the chemical equation bel

Answer: 2.67 moles of Phosphine are produced

Explanation:

From the equation 3H2 + P2 → 2PH3

3 moles of hydrogen (H2) = 2 moles of Phosphine (PH3)

4 moles of hydrogen = X moles of PH3

Then, cross multiply

X moles of Phosphine = (4 x 2) / 3

= 8 / 3

= 2.67 moles

Thus, 4 moles of hydrogen produces 2.67 moles of Phosphine

2SO3(g)⟶2S(s)+3O2(g)ΔH=+790kJ. How many kilojoules are required when 2.1 moles of SO3 reacts?
guapka [62]

<u>Given:</u>

Enthalpy change (ΔH) for SO3 decomposition = +790 kJ

Moles of SO3 = 2.1 moles

<u>To determine:</u>

Energy required when 2.1 moles of SO3 reacts

<u>Explanation:</u>

The decomposition reaction is -

2SO3(g) → 2S(s) + 3O2 (g)

Energy required when 2 moles of SO3 reacts is 790 kJ

Thus, for 2.1 moles of SO3 the energy requirement would be

= 2.1 moles SO3 * 790 kJ/2 moles SO3 = 829.5 kJ

Ans: 830 kJ are required when 2.1 moles of SO3 reacts.

What is the limiting reactant if 10 moles of NH 3 react with 30.0 moles of NO ?
Elis [28]

Answer:

NO is the limiting reactant.

Explanation:

4NH3 + 6NO --> 5N2 + 6H2O

Molar ration NH3 : NO = 10: 30 = 1: 3

Stoichiometric molar ration NH3:NO = 4:6 = 2:3

NO is the limiting reactant.

What is the hybridization around the O atom?
baherus [9]
Your answer is......... with little bit explains....and read correctly.......The nitrogen is sp3 hybridized which means that it has four sp3 hybrid orbitals. Two of the sp3 hybridized orbitals overlap with s orbitals from hydrogens to form the two N-H sigma bonds. One of the sp3 hybridized orbitals overlap with an sp3 hybridized orbital from carbon to form the C-N sigma bond. The lone pair electrons on the nitrogen are contained in the last sp3 hybridized orbital. Due to the sp3 hybridization the nitrogen has a tetrahedral geometry. However, the H-N-H and H-N-C bonds angles are less than the typical 109.5o due to compression by the lone pair electrons.
