•Burning a log of wood
•Mixing an acid with a base, producing water and a salt.
•Photosynthesis - a process in which carbon dioxide and water are changed into sugars by plants.
•Cracking heavy hydrocarbons to create lighter hydrocarbons (part of the process of refining oil).
•Cooking examples: popcorn, cake, pancakes, and eggs
<span>The
conceptual model provides a concept of how the components of an atom
are arranged, implying a similarity of the forces acting between those
components.
It is important to note that the conceptual model is not necessarily
correct or accurate. It simply provides a model which forms the basis
for the discussion of the concepts involved.
Science is all about the discussion -- with the expressed aim of
improving the conceptual model to the point that it is self-consistent
and consistent with the existing body of accepted knowledge. [The
hardest part is knowing when and how to question the body of accepted
knowledge.] </span>
Answer: photosynthesis - chloroplast; cellular respiration - mitochondria
Explanation:
Answer:
True
Explanation:
Water logging occurs when water table rises to the root zone as a result of over irrigation.
Answer:
D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Explanation:
The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.
The balanced chemical equation is mentioned as under:
C₆H₁₂O₆ + 6 O₂ -> 6 CO₂ + 6H₂O + Energy.
(Glucose) (Oxygen) (Carbon (Water)
dioxide)
If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.
