Calculate Δ H ∘ in kilojoules for the reaction of ammonia (Δ H ∘ f =−46.1 kJ/mol) with O 2 to yield nitric oxide NO (Δ H ∘ f =91

.3 kJ/mol) and H 2 O(g) (Δ H ∘ f =−241.8 kJ/mol) , a step in the Ostwald process for the commercial production of nitric acid.

What term describes a carbon atom that has four different groups bonded to it?
oee [108]
A carbon which is attached to four different atoms or group of atoms with different environment is called as Chiral Carbon or Asymmetric Carbon.

Non-<span>superimposable:
</span>                                     The mirror image (molecule) of chiral carbon cotaining compounds are Non.Superimposable on each other. They are called enantiomers of each other.

Polarized Light and Chiral Carbon:
                                                       When a polarized light is allowed to fall on either enantiomer of chiral compound, it is rotated other clockwise or anti-clockwise.

Examples:
                Below are three axamples of compounds containing chiral carbon.

Which formula can be used to calculate the theoretical yield?
Bas_tet [7]

Answer:

Option C, (Actual yield ÷ percent yield) × 100

Explanation:

Theoretical yield is defined as the total amount of product formed for given reactants in a chemical reaction.  It is an ideal case which assumes no exceptions or wastage.

The mathematical relation between the actual yield, percent yield and theoretical yield is as follows -

P.Y. = \frac{M_{A.Y.}}{M_{T.Y.}} * 100

Where

P.Y. represents the percent yield a

M A.Y. represents the mass obtained from actual yield

M T.Y. represents the mass obtained from theoretical yield

Hence, if we rearrange the formula, we get -

M_{T.Y.} = \frac{M_{A.Y.}}{P.Y.} * 100

Hence, option C is correct
