Answer:
Human various activities like burning fossils and huge land cover changes contribute to increasing the carbon dioxide of atmosphere.
Explanation:
- Carbon dioxide level in atmosphere is increasing naturally by organism respiration, decay, volcanoes erupt and carbonated rocks are weathered.
- Human activities like, urbanization, deforestation, vegetation pattern changes results in changes to reflectivity of earth surface and emmision through burning fossils fuels/forest and cement production are causining an increase in atmospheric carbon di oxide level. When fossils fuel burn the carbon combine with oxygen to form CO2.
- All these processes ultimately contribute to global warming.

Answer:
60 grams
60 milliliters of water weighs 60 grams. (or precisely 60 grams.
Explanation:
Actually, it is INNATE IMMUNITY. That is the proven right answer so be careful.
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.
Weak acids and bases undertake reversible reactions. For example, carbonic acid: H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq).
The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents (A and B or C and D) and the equilibrium constant, K. The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction.[2] So, when the free energy change is large (more than about 30 kJ mol−1), then the equilibrium constant is large (log K > 3) and the concentrations of the reactants at equilibrium are very small. Such a reaction is sometimes considered to be an irreversible reaction, although in reality small amounts of the reactants are still expected to be present in the reacting system. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction
