Answer:

C.it has a lower melting temperature

Explanation:

A good way to solve this problem may be to think about a simple ionic compound, such as salt, NaCl:

NaCl easily disolves in water, so options A and B are true about ionic compounds.

Salt powder does not conduct electricity, however a concentrated solution of salt in water does. Meaning that option D is true as well.

NaCl has a melting point of 801 °C, not particularly a low value. Thus the correct option is C.

What is the conjugate acid of HCO3? A) H30+ B) H20 C) CO32- D) OH E) H2CO3

jolli1 [7]

<u>Answer:</u> The correct answer is Option E.

<u>Explanation:</u>

According to the Bronsted-Lowry conjugate acid-base theory:

An acid is defined as a substance which looses donates protons and thus forming conjugate base.

A base is defined as a substance which accepts protons and thus forming conjugate acid.

To form a conjugate acid of $HCO_3^-$ , this compound will accept one proton to form $H_2CO_3$

The conjugate acid formed is named as carbonic acid.

Hence, the correct answer is Option E.

How fast will benzene solidify

White raven [17]

Explanation:

What benzene is

Benzene is a chemical that is a colorless or light yellow liquid at room temperature. It has a sweet odor and is highly flammable.

Benzene evaporates into the air very quickly. Its vapor is heavier than air and may sink into low-lying areas.

Benzene dissolves only slightly in water and will float on top of water.
