Answer:
Dynamic equilibrium is a state in which reactant is converted into products at the same rate. At the beginning of a reaction, the reactants are converted to products and reaction goes into forwarding direction.
But in reversible reaction products start changing into reactants and reaction goes in the reverse direction until an equilibrium is reached. The state where the rates of all the reactants and products become equal and no more changes take place except the concentration is called dynamic equilibrium.
All the changes in dynamic equilibrium cancel out each other and the system seems to be at equilibrium.
Answer:
2 Fe 2O 3 + 3 C → 4 Fe + 3 CO 2
Explanation:
yeap
He. it is a noble gas and therefore has a full outer shell of electrons. it does not need to gain or loose any.
Metal ore has other elements in it as well. Also sediment and stone might cover the ore. We don't want to have a phone with sediment on it do we? thus these few reasons are why.
Answer:
54 grams of H₂O
Explanation:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
Ratio is 4:6.
Let's convert the mass of ammonia in moles
Mass / Molar mass = Mol
34 g / 17 g/m = 2 moles
If 4 moles of ammonia are needed to produce 6 mol of water
2 mol of NH₃ will produce ( 2 .6 )/4 = 3 moles
Molar mass water = 18 g/m
Mass = mol . molar mass → 3 m . 18 g/m = 54 grams
