Answer:
2.99×10²⁵ molecules of CO₂ are produced
Explanation:
Decomposition reaction is:
Ca(HCO₃)₂ => CaO(s) + 2CO₂(g) + H₂O(g)
Ratio is 1:2. Let's make a rule of three:
1 mol of bicarbonate can produce 2 moles of CO₂
Therefore, 24.9 moles of bicarbonate may produce, 49.8 moles (24.9 .2 )/1
Let's determine the number of molecules
1 mol has 6.02×10²³ molecules
49.8 moles must have (49.8 . 6.02×10²³) / 1 = 2.99×10²⁵ molecules
<u>Mendeleev </u><u>positioned elements in the periodic table in</u><u> increasing order </u><u>of their atomic numbers, such that </u><u>elements </u><u>having identical chemical properties and characteristics plunge into the </u><u>same group.</u>
What is Mendeleev's periodic table called?
- In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
- Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
- The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.
- Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
- He also imagined having other elements with possessions similar to those of these other elements.
- In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

Answer:
A large point of evidence in this would be the rate of increase in how fast the polar ice caps are melting and the ocean is rising as a result. As the climate is getting warmer so are the oceans and this is causing the ice caps which are in the ocean.
