The Roman numerals in a cation's name indicate: THE POSITIVE CHARGE ON THE CATION

Cations are metallic atoms that loosely hold it electrons, making it easy to lose electrons.

The Roman numerals in a cation's name not only indicates the charge on the cation but it makes it easier to distinguish cations that share the same metal name.

Answer: Option (c) is the correct answer.

Explanation:

When an element gain electrons then it acquires a negative charge. For example, Cl + 1e^{-} \rightarrow Cl^{-}

Whereas when an element loses electrons then it acquires a positive charge.

For example, Fe \rightarrow Fe^{2+} + 2e^{-1}

The atom Fe^{2+} can also be written using roman numerals as Fe(II).

Therefore, we can conclude that roman numerals in a cation's name indicate the positive charge on the cation.

Calculate the heat absorbed by a sample of water that has a mass of 45.00 g when the temperature increases from 21.0oC to 38.5 o
Elenna [48]

Answer:

The heat absorbed by the sample of water is 3,294.9 J

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

The sensible heat of a body is the amount of heat received or transferred by a body when it undergoes a temperature variation (Δt) without there being a change of physical state (solid, liquid or gaseous). Its mathematical expression is:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

  • Q=?
  • m= 45 g
  • c= 4.184 \frac{J}{g*C}
  • ΔT= Tfinal - Tinitial= 38.5 C - 21 C= 17.5 C

Replacing:

Q= 4.184 \frac{J}{g*C} * 45 g* 17.5 C

Solving:

Q=3,294.9 J

<u><em>The heat absorbed by the sample of water is 3,294.9 J</em></u>

<u><em></em></u>
