Ionization energy of atoms decrease as we move down a column on the periodic table.
Answer: Ionization energy
<u>Explanation:
</u>
The periodic table consists of elements arranged in rows (periods) and columns (groups). The arrangement of elements in a column are made based on the increasing order of atomic radii from top to bottom of column.
As the atomic radii increase in group from top to bottom, the number of electrons increase along the group lead to shielding effect. Since the count of valence electrons are same for all elements in a group, the effective nuclear charges also same.
But the increase in the atomic number lead to shielding and increase in electrons occupied in farther shells from nucleus. This leads to deduce ionisation energy when move down a group.

Answer:
Ⓓ The process follows the law of conservation of mass and energy is found in the product
Explanation:
This question depicts PHOTOSYNTHESIS, which is the process employed by green plants to manufacture their food in form of sugars (glucose). The general equation, which was given in the question is as follows:
6CO2 + 6H2O + energy → C6H12O6 + 6O2
This chemical reaction follows the LAW OF CONSERVATION OF MASS, which states that the amount of matter in reactant must equate that of the product. In this case, each element contains the same number of atoms in both reactant side and product side.
Also, energy is contained in the product but stored in the chemical bonds of the glucose molecule formed.
Density = mass /volume of the body. mass = 10.88 g, volume of the liquid displaced= 49.4-43.5=5.9 ml.
density = 10.88/5.9=1.844 g/ml~1.84 g/ml
The volume displaced is exactly the same as that of the body (The Eureka fro Archimedes!)
