5 0

Answer:

  the number of neutrons in the nucleus

Explanation:

The mass number 205 is the total number of protons and neutrons in the nucleus. Lead has 82 protons, so a mass number of 205 indicates a nucleus with 123 neutrons.

Similarly, the mass number 208 indicates a lead nucleus with 126 neutrons.

The difference in atomic structure is the difference in the number of neutrons in the nucleus.

The concentration of hydroxide ions is greater than the concentration of hydronium ions for acidic solution. True or false.
larisa86 [58]

Answer: False

Explanation:

An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.

A base is defined as the substance which looses hydroxide ions when dissolved in water.

If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.

If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.

tangare [24]

Answer:

An emulsifying agent is typically characterized by having <u><em>d. one polar end and one nonpolar end.</em></u>

Explanation:

Emulsifiers are substances that have the ability to bind, for example, fats with those substances that have mostly water in their conformation. In other words, the emulsifier facilitates mixtures of two or more immiscible liquid substances.

This is because the molecules of an emulsifier are often lipophilic (attract oil) at one end and hydrophilic (attract water) at the other. In other words it consists of a polar (hydrophilic) head group and a non-polar (hydrophobic) tail.

<u><em>An emulsifying agent is typically characterized by having d. one polar end and one nonpolar end.</em></u>
