Answer:
Photosynthesis reactions are naturally occurring processes that take place in all green plants and most algae. During this process the plant uses light energy, carbon dioxide, and water to make food and then releases oxygen which all living organisms require to the atmosphere.During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose
Explanation:
Answer: The shape of a molecule is dependent on the arrangement of the terminal atoms around the central atom.
Explanation:
In the VSEPR, the terminal atoms are treated as electron pairs arranged around the central atom in such a way as to minimize repulsion between them. The number of terminal atoms around the central atom are counted as the electron pairs. Our major concern is how these electron pairs arrange themselves around the central atom.
Answer:
2 moles of C2H6 are required to form 4 moles of CO
therefore for 2 moles of CO, 1 mole of C2H6 is required
The answer would be hydrogen is released at the negative anode.
Answer: Hurricane is not a man-made environmental change.
Explanation:
Changes which take place naturally in the environment without any force or work done by man towards causing that change are called non-man made environmental changes.
For example, hurricane is a natural environment change because a hurricane is formed moist and warm air above water surface of sea, oceans or rivers begin to rise.
This rising air is replaced by the cooler air present in the atmosphere. The continuation of this process leads to the formation large clouds and thunderstorms which occurs in the form of hurricane.
Whereas pollution is caused by vehicles driven by man, from chimneys of factories etc. So, it is a man-made environmental change.
Chemical spill can occur due to mishandling by man in laboratories or chemical labs.
Deforestation also occurs by man as they cut the trees for various needs to theirs.
Thus, we can conclude that hurricane is not a man-made environmental change.
