Answer:
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
Explanation:
You might expect that sheltered areas of stone buildings and monuments would not be affected by acid precipitation. However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2), it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain.
Becuase the cell has a lower concentration that the solution it is placed in, the solution is considered hypertonic. The cell will lose water through osmosis and will shrink, the 2nd option is correct.
Neutrons
The atomic mass is the weight of the protons and neutrons in the nucleus.
Answer:
Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.
Explanation:
Answer:
carbon if only one answer allowed, if check multiple, carbon, hydrogen, and oxygen.
Explanation:
The common elemental ingredients are carbon, hydrogen, and oxygen. They all contain the element carbon. They contain simpler units that are linked together making larger molecules.
