Answer: H2O
Explanation: The given balanced chemical reaction is,
This reaction is a reversible reaction.
The rate of forward reaction will be,
The rate of backward reaction will be,
And at equilibrium the rate of reaction is equal to the rate of backward reaction divided by the rate of forward reaction.
Answer:
There are 3 bonding pairs of electrons
Explanation:
For every bond there is one bonded pair of electrons. NH₃ has three N-H bonds, so has three bonding pairs of electrons along with a lone pair of electrons
Answer:
1. Increasing the concentration of the acid
2. Increasing the temperature
Explanation:
CaCO₃ + 2HCl ⟶ CaCl₂ + H₂O + CO₂
Increasing the concentration of the acid increases the number of hydronium ions in contact with the surface of the CaCO₃ per unit time.
Increasing the temperature increases the kinetic energy of the hydronium ions, so they hit the surface of the CaCO₃ mor frequently and with greater force.
3. is wrong. The bigger the pieces, the smaller the surface area that is available for reaction.
Among the choices, the best answer is alcohol. However, the most common groups of organic compounds in fuels are the alkanes and alkenes. Alcohol can also be used in fuel, especially bioethanol. Bioethanol is a common additive in fuels for motor vehicles, and is made from corn or sugar.
