<em>Answer:</em>

  • The atom have a full valence electron shell.

<em>Explanation:</em>

  • My question is that why covalent bonds take place?

Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.

Alla [95]

Answer:

  • CO₃²⁻ +  H₂O <---------------->  HCO₃⁻ + OH⁻
  • The chemical formula of the precipitate is Fe(OH)₃

Explanation:

  • Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociate in water. Carbonate ions is a weak base and combine with water to form hydroxide ions (OH⁻), CO₃²⁻ +  H₂O <---------------->  HCO₃⁻ + OH⁻
  • Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.

Determine the heat energy needed to raise the temperature of 120 grams of ice at -5 to steam at 115°
CaHeK987 [17]

Answer:

Q = 30355.2 J

Explanation:

Given data:

Mass of ice = 120 g

Initial temperature = -5°C

Final temperature = 115°C

Energy required = ?

Solution:

Specific heat capacity of ice is = 2.108 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Q = m.c. ΔT

ΔT = T2 -T1

ΔT = 115 - (-5°C)

ΔT = 120 °C

Q = 120 g × 2.108 j/g.°C × 120 °C

Q = 30355.2 J
