The correct name for the ion Fe2+ is
forsale [732]

Fe is the symbol of the metal iron. This is because the Latin name of iron is Ferrum. Iron shows more than one valency and forms Fe2+ and Fe3+ ions. Fe2+ ion is formed when an atom of iron loses 2 electrons to form a cation and Fe3+ ion is formed when an atom of iron loses 3 electrons to form a cation. For this reason, Fe2+ is known as the ferrous ion.

Therefore, the correct name for the ion Fe2+ is ferrous ion.

A student must use 220 mL of hot water in a lab procedure. Calculate the amount of heat required to raise the temperature of 220
Inessa [10]

Answer:

64,433.6 Joules

Explanation:

<u>We are given</u>;

  • Volume of water as 220 mL
  • Initial temperature as 30°C
  • Final temperature as 100°C
  • Specific heat capacity of water as 4.184 J/g°C

We are required to calculate the amount of heat required to raise the temperature.

  • We know that amount of heat is calculated by;

Q = mcΔT , where m is the mass, c is the specific heat, ΔT is the change in temperature.

Density of water is 1 g/mL

Thus, mass of water is 220 g

ΔT = 100°C - 30°C

    = 70°C

Therefore;

Amount of heat, Q = 220g × 4.184 J/g°C × 70°C

                               = 64,433.6 Joules

Thus, the amount of heat required to raise the temperature of water is 64,433.6 Joules
