Hydrogen gas has been suggested as a clean fuel because it produces only water vapor when it burns. If the reaction has a 88.9%

GaryK [48]

Answer:

Mass of hydrogen = 667 kg (Approx)

Explanation:

Given:

Mass of water = 593 kg

Yield rate = 88.9%

Find:

Mass of hydrogen

Computation:

Mass of hydrogen = [Mass of water / Yield rate]100

Mass of hydrogen = [593 / 88.9]100

Mass of hydrogen = 667.04162

Mass of hydrogen = 667 kg (Approx)

Phosphorus p4 burns in oxygen to form diphosphorus pentoxide what is the balanced chemical equation representing this chemical r

ahrayia [7]

Answer:

P₄ + 5O₂ → 2P₂O₅

Explanation:

Phosphorus burn in the presence of air and produced diphosphorus pentoxide.

Chemical equation:

P₄ + O₂ → P₂O₅

Balanced chemical equation:

P₄ + 5O₂ → 2P₂O₅

Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.

Coefficient with reactant and product:

P₄ 1

O₂ 5

P₂O₅ 2

The reaction:L-glutarmate + pyruvate → α-ketoglutarate + L-alanine is catalyzed by the enzyme L-glutamate-pyruvate aminotransfer

sveticcg [70]

Answer:

Reaction Quotient, Kq = {[a-ketoglutarate]x[L-alanine]}/{[L-glutamate]x[pyruvate]}

or, Kq = {(1.6x10-2)x(6.25x10∧-3)}/{(3x10∧-5)x(3.3x10-4)} = 1.01 x 10∧4

Since Kq > Keqb ; therefore the reaction will proceed in the backward direction, in order words the reaction will not occur in forward direction. i.e formation of reactants will be favored.

solution:

the change in the boiling point is given as,

dTbp =2.30°c

elevation constant for the solvent is given by,

kb=0.512°c/m

$molality=\frac{dTBP}{KB\times m}\\=\frac{2.30}{0.512c/m}$

= 4.49m

Classify each of the four compounds as a conjugated, isolated, or cumulated diene. Compound A: Two alkenes are joined by a sigma

Lina20 [59]

Explanation:

Conjugated diene is the one that contains alternate double bonds in its structure. That means both the double bonds are separated by a single bond.

Cumulated diene is the one that contains two double bonds on a single atom. This means it has two double bonds continuously.

Isolated double-bonded compound has a single bond isolated by two to three single bonds.

Compound A: Two alkenes are joined by a sigma bond.

For example:

$-CH_2=CH-CH=CH2-$

It is a conjugated diene.

Compound B: Two alkenes are joined by a C H 2 group.

It is a cumulative diene.

Compound C: Two alkenes are joined by C H 2 C H 2.

Then it is an isolated alkene.

Compound D: A cyclohexene has a double bond between carbons 1 and 2. Carbon 3 is an sp 2 carbon that is bonded to another s p 2 carbon with an alkyl substituent.

Hence, compound D is a conjugated diene.
