I think you mean ionic bond and not conic bond. The pair of elements that form an ionic bond are barium and chlorine.

Can You Tell?<br> Pepsinogen is released in the stomach. Why can't it digest stomach walls?
miv72 [106K]

Answer:

Specific cells within the gastric lining, known as chief cells, release pepsin in an inactive form, or zymogen form, called pepsinogen. By doing so, the stomach prevents the auto-digestion of protective proteins in the lining of the digestive tract.

C. Hair dryer

Explanation:

Alternating Current

The other kind of electricity is called alternating current, or AC. Power plants produce this

type of electricity. It is carried by large power lines from the plant to your home. When you

plug a TV, a lamp, or a hair dryer into the wall socket, you are using this type of electricity.

photoshop1234 [79]

<span>I’ve answered this question before so if these are the choices to the question presented:

An oxygen atom double-bonded to a carbon atom, with a hydrogen atom single-bonded to the same carbon atom. </span><span>

<span>A hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain. </span>

<span>A carbon atom single-bonded between two other carbon atoms, with an oxygen atom double-bonded to the central carbon atom as well. </span>

<span>An oxygen atom single-bonded between two carbon atoms within a carbon chain. 


Then, the answer would be “a hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain.<span>”</span></span></span>

EXTRA POINTSSS 1. A solution at 25 degrees Celsius is 1.0 × 10–5 M H3O+. What is the concentration of OH– in this solution?
AlekseyPX

Answer:

Concentration of OH⁻:

1.0 × 10⁻⁹ M.

Explanation:

The following equilibrium goes on in aqueous solutions:

\text{H}_2\text{O}\;(l)\rightleftharpoons \text{H}^{+}\;(aq) + \text{OH}^{-}\;(aq).

The equilibrium constant for this reaction is called the self-ionization constant of water:

K_w = [\text{H}^{+}]\cdot[\text{OH}^{-}].

Note that water isn't part of this constant.

The value of K_w at 25 °C is 10^{-14}. How to memorize this value?

  • The pH of pure water at 25 °C is 7.
  • [\text{H}^{+}] = 10^{-\text{pH}} = 10^{-7}\;\text{mol}\cdot\text{dm}^{-3}
  • However, [\text{OH}^{-}] = [\text{H}^{+}]=10^{-7}\;\text{mol}\cdot\text{dm}^{-3} for pure water.
  • As a result, K_w = [\text{H}^{+}] \cdot[\text{OH}^{-}] = (10^{-7})^{2} = 10^{-14} at 25 °C.

Back to this question. [\text{H}^{+}] is given. 25 °C implies that K_w = 10^{-14}. As a result,

\displaystyle [\text{OH}^{-}] = \frac{K_w}{[\text{H}^{+}]} = \frac{10^{-14}}{1.0\times 10^{-5}} = 10^{-9} \;\text{mol}\cdot\text{dm}^{-3}.
