Answer:
A) increasing tension in the vibrating object.
Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid.
Alfred Wegener
Explanation:
Alfred Wegener in 1912, proposed the theory of continental drift from his careful studies of different land masses. From his observations, he suggested the following:
- Some fossils of tropical plants were found in polar and temperate regions.
- Fossils of mesosaurus were found in South America and South Africa now separated by the Atlantic ocean.
- He fitted the continents into a giant land mass puzzles.
- Coal beds in Europe were similar to those in United States.
- Mountain chains in the edge of West Africa was similar to that of Eastern part of South America.
His theory lacked a mechanism which facilitated the plate movement.

Answer :
a) The concentration of 
at equilibrium is 0.08 m.
b) The concentration of 
at equilibrium is 0.26 m.
Solution :
The equilibrium reaction is,
![Fe^{3+}+SCN^-\rightleftharpoons [FeSCN]^{2+}](https://tex.z-dn.net/?f=Fe%5E%7B3%2B%7D%2BSCN%5E-%5Crightleftharpoons%20%5BFeSCN%5D%5E%7B2%2B%7D)
Initial concentration 0.230 0.410 0
At equilibrium (0.230 - x) (0.410 - x) x
Given x = 0.150
Therefore,
The concentration of = 0.230 - x = 0.230 - 0.150 = 0.08
The concentration of = 0.410 - x = 0.410 - 0.150 = 0.26
Thus, the concentration of at equilibrium is 0.08 m.
The concentration of at equilibrium is 0.26 m.
Explanation:
20.0 moles= 80.1 or 80.05g
5.00 moles= 20.0g
1.20×1025moles= 4923.2g
1.00 moles= 4.00g
80.0 moles= 320.2g
