Answer: Dominant

Explanation:

A gene can exists in forms known as alleles. An allele that mask the presence of another is said to be dominant while Tue masked allele is said to be recessive.

Hence, in the presence of the dominant allele the traits carried by the recessive is not visibly expressed in the organism but masked by the expressed traits of such dominant allele

Thus, the form of gene is dominant

Sketch and label a covalent bond and an ionic bond (you do not need to draw the metallic bond or intermolecular force). Describe
Nat2105 [25]

Answer:

See attached image

Explanation:

An ionic bond is a type of chemical bond in which occurs an electrons transfer, where one of the atoms act as a donor and the other act as the acceptor. Compound with ionic bonds are very stables and strong because of the attraction of the opposite charges. These attractions help ions stay together forming solid nets.

A covalent bond is a type of chemical bond in which the electrons are shared. Unlike the ionic bond, the atoms act at the same time as donors and acceptors sharing their electrons. The covalent bond keeps the atoms together because an electrostatic force, thus this bond is weaker than the ionic bond.

A metallic bond is a force which keeps together metallic atoms. In this type of bond, there is no transfer or sharing of electrons. The atoms are kept together because of an electrostatic force. Since there is no electron exchange involved a metallic bond is weaker than the other two.

In diamond, every carbon atom shared four electrons with other carbon atoms between a covalent bond. These form a regular tetrahedron. On the other side, graphite has a layer structure, in which every layer hold carbon atoms wich shared electrons with other tree atoms. All the layers stay together because of the Van der Waals force. These difference in bonds cause to have different properties, diamond is one of the hardest materials and graphite it is not.

The equilibrium-constant expression for a reaction written in one direction is the __________ of the one for the reaction writte
VLD [36.1K]

Answer:

  • <u>    reciprocal   </u>

Explanation:

The <em>equilibrium constant</em> for an <em>equilibrium reaction </em>is the ratio of the equilibrium constant for the forward reaction, Kf, to the equilibrium constant for the reverse reaction, Kr:

  • For A ⇄ B

  • The forward reaction is: A → B, with rate constant is Kf = K₁ and
  • The reverse reaction is: B → A, with rate constant Kr = K₂

            K_{eq}=\dfrac{K_f}{K_r}=\dfrac{K_1}{K_2}

When you write the reaction in the other reaction, the forward and the reverse reaction are exchanged:

  • For B ⇄ A

  • The forward reaction is B → A, with rate constant Kf = K₂
  • The reverse reaction is A → B, with rate constant Kr = K₁

             

             K'_{eq}=\dfrac{K_f}{K_r}=\dfrac{K_2}{K_1}

As you see:

          K'_{eq}=\dfrac{1}{K_{eq}}

Thus, <em>the equilibrium-constant expression for a reaction written in one direction is the </em><em><u>    reciprocal</u></em><em>___</em><em> of the one for the reaction written for the reverse direction.</em>

Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or
natka813 [3]

Answer:

Explanation:

You need to remember that the oxidation number of H is +1, except when it is in a metal hydrites like NaH, where its oxidation number is -1. Then, the oxidation number of O is -2, but in peroxides is -1. So with these rules you just have to multiply the ox. number with the name of atoms and all the elements in the reaction must sum 0.
