Answer:
The correct answer is c add more HCO3- by adding NaHCO3.
Explanation:
The reaction mentioned in the question is carried out by bicarbonate buffer system of our body to maintain the normal acid base balance.
Now concentration of the reactant (H2C03) is decreased then NaHCO3 should be added which undergo breakdown to release bicarbonate ions(HCO3-).
The released bicarbonate ions then reacts with H+ to form Carbonic acid(H2CO3).Thus homeostasis of H2CO3 is maintained.
Conductors are better than insulators to carry electric current because they give the electricity the ability to flow freely throughout circuits. This helps the insulator to do its job of containing the electric charge. Examples of this would be a tv plug - the rubber surrounding the TV plug helps to keep the conductors (wires) in place, thus helping to facilitate an electric charge.
Answer:
3
Explanation:
Subscript basically tells you the number of element or ions present in a compound. In this case the subscript of carbon which is 3 denotes that only three carbon atoms is present in the compound.
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.
