Which enzymes show very broad substrate specificity and can therefore be used to produce several higher alcohols.Select one:

a. 2-keto acid decarboxylase AND alcohol dehydrogenase
b. alcohol dehydrogenase
c. transaminase
d. acetolactate synthasee. 2-ketoacid decarboxylase

Answer:

D. CH₃CH₂C(CH₃)₂C≡CCH(CH₃)₂  

Explanation:

You start numbering from the end closest to the triple bond (on the right). The triple bond is between C3 and C4, and there is one methyl group on C3 and two on C5.

A. CH₃CH₂CH(CH₃)C≡CCH₂CH(CH₃)₂ is wrong. The longest chain has eight C atoms, so the compound is an octyne.

B. CH₃CH₂CH(CH₃)C≡CC(CH₃)₃ is wrong. This is a molecule of 2,2,5-trimethylhept-3-yne.

C. (CH₃CH₂)₂C≡CCH₂CH₃ is wrong. This is a molecule of 6-ethyl-5-methylhept-3-yne.

E. CH₃CH₂CH₂CH(CH₃)C≡CC(CH₃)₃ is wrong. The longest chain has eight C atoms, so the compound is an octyne.

Answer:

Decomposition= one-reactant

Combustion= 2-reactants

Single displacement= 2-reactant

Explanation:

The percent yield of the reaction : 89.14%

Further explanation

Reaction of Ammonia and Oxygen in a lab :

4 NH₃ (g) + 5 O₂ (g) ⇒ 4 NO(g)+ 6 H₂O(g)

mass NH₃ = 80 g

mol NH₃ (MW=17 g/mol):

mass O₂ = 120 g

mol O₂(MW=32 g/mol) :

Mol ratio of reactants(to find limiting reatants) :

mol of H₂O based on O₂ as limiting reactants :

mol H₂O :

mass H₂O :

4.5 x 18 g/mol = 81 g

The percent yield :

The charge on the most stable ion of bromine is - 1.

What is an ion?

A charged atom or molecule is known as an ion. It has a charge because the atom or molecule's number of protons and electrons is not equal. Depending on whether an atom has more electrons than protons or fewer electrons than protons, an atom might become positively or negatively charged.

An atom is referred to be an ION when it is drawn to another atom due to an imbalance in its electron and proton numbers. A negative ion, or ANION, is an atom that contains more electrons than protons. A positive ion is one that has more protons than electrons.

Either there are too many or not enough electrons in a charged atom. Atoms in DS1 are heated to extremely high energy and unstable state. Then, a cathoderay in the thruster chamber discharges electrons, which strike the. Some of the electrons in the atoms in the chamber are stripped or knocked away when the electrons strike them. Plasma is created when a mass of charged, overheated atoms with free electrons.

Therefore, the charge on the most stable ion of bromine is - 1

Br (Bromide)

-1 or Br- hope this helps

Answer:

20 mL

Explanation:

We can determine the required volume of the concentrated (17.5 M) H₂SO₄ solution by using the C₁V₁=C₂V₂ formula:

• 17.5 M * V₁ = 14.00  M* 100 mL

• V₁ = 80 mL

As out of the 100 mL of the final solution, 80 mL are from the concentrated H₂SO₄ solution, the remaining 20 mL are of water (H₂O).

The molar mass of Fe2(SO3)3 is 351.8796 moles.

What is molar mass?

Molar mass is defined as the mass equivalent of an element's or a chemical compound's Avogadro number of atoms or molecules, respectively. A mole is defined as the quantity of atoms, molecules, or ions that are present in a substance. It is additionally referred to as the volume of material that contains the same number of discrete units.

Molar mass of Fe2(SO3)3

= 2 × 55.845 + 3 × 32.065 + 9 × 15.9994

= 111.69 +  96.195 + 143.9946

= 351.8796 moles.

The substance iron(III) sulfite, sometimes known as ferrous sulfite, has the chemical formula Fe2(SO3)3. The family of inorganic compounds known as iron(III) Sulphate, sometimes known as ferric Sulphate, has the formula Fe2(SO4)3(H2O)n.

Thus, the molar mass of Fe2(SO3)3 is 351.8796 moles.
