Answer:
a) Ag(NH₃)₂⁺, Cl⁻.
b) NH₃.
c) AgCl.
Explanation:
Based on LeChatelier's law, a system in chemistry can change responding to a disturbance of concentration, temperature, etc. in order to restore a new state.
In the reaction:
AgCl(s) + 2NH₃(aq) ⇌ Ag(NH₃)₂⁺(aq) + Cl⁻(aq)
When reactants are added, the system will produce more products restoring the equilibrium and vice versa. A reactant in solid state doesn't take part in the equilibrium, thus:
a) Ag(NH₃)₂⁺, Cl⁻. The addition of products will shift the equilibrium to the left
b) NH₃. The addition of reactant will shift the equilibrium to the right.
c) As AgCl is in solid phase, will not shift the equilibrium in either direction.
In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
Mass % of NaOH solution = 10 % (m/v)
Mass of NaOH required to prepare 1 L solution:
= 100 g NaOH
Answer:
The answer to your question is 194 g
Explanation:
Molecular mass is the sum of all the masses of the atoms that form a molecule.
In the problem, we have C₈H₁₀N₄O₂ which means
atomic mass number of atoms total
Carbon 12 8 12 x 8 = 96
Hydrogen 1 10 1 x 10 = 10
Nitrogen 14 4 14 x 4 = 56
Oxygen 16 2 16 x 2 = 32
194 g
An atom. An atom has no charge. The number (and charge) of protons in atom's nucleus is balanced by the electrons orbiting the nucleus. If it had charge it would be called an ion.
