A student reacts magnesium with hydrochloric acid. Write the balanced chemical equation

Mg+2HCl→MgCl2+H2

200

A student increases the temperature of a reaction mixture from 25°C to 50°C. Explain why the reaction rate increases.

Particles have more kinetic energy, move faster, and a greater proportion of collisions have enough energy to overcome the activation energy.

Describe whether Covalent network and Covalent Molecular are Soluble stating the reasons why?

Covalent Network:

  • Does not dissolve in water
  •  Strong covalent bonds hold all atoms together in a giant network
  •  Water molecules cannot break these bonds

Covalent Molecular:

  • Water is polar
  •  Many covalent molecular substances are non-polar some are polar though
  •  Like dissolves like

A catalyst is added to a reaction. Describe what happens to:

  1. Activation energy
  2. Enthalpy change (ΔH\Delta HΔH)
  • Activation energy decreases.
  • Enthalpy change remains unchanged.

  •  
  • Very high melting point     (>1600°C)
  •  
  • Insoluble in water
  •  
  • Does not conduct     electricity as a solid
  •  
  • Does not conduct     electricity when molten
  •  
  • Contains only one element
  •  
  • Extremely hard

Which of the following is the most likely explanation for the structure and bonding of X?

A. X is an ionic lattice because strong electrostatic forces require large amounts of energy to overcome.

B. X is a metallic lattice because the atoms are held together by a sea of delocalised electrons.

C. X is a covalent network lattice because all atoms are joined by strong covalent bonds throughout the entire structure.

D. X is a molecular covalent substance because strong intermolecular forces exist between the molecules.

The equilibrium reaction is:

N2(g)+3H2(g)⇌2NH3(g)N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)N2(g)+3H2(g)⇌2NH3(g)

Predict the effect of increasing the pressure on the position of equilibrium.

The equilibrium shifts to the right, producing more ammonia.
