Answer:
In the modern period table, the elements are arranged in the increasing order and depending on their physical and chemical properties they are classified into the different groups and atoms.
Alkali metals differ from alkaline earth metal in the atomic structure and their properties as all the alkali metals consist electron in the outer-most shell. And the earth alkaline metals has two outer electron in their shell. So, for achieving the configuration of noble gas the alkali metals loses one electron and the alkaline metal lose two electrons.
1. Both evaporation and condensation are steps in the water cycle.
2. Both are affected by atmospheric conditions.
Let me know how you did, good luck! :D

Answer:</h3>
0.90J/g°C
<h3>
Explanation:</h3>
We are given:
Mass of Aluminium = 10 g
Quantity of heat = 677 Joules
Change in temperature = 125°C - 50°C
= 75°C
We are required to calculate the specific heat capacity of Aluminium
But, Quantity of heat = Mass × specific heat × Change in temperature
Q = mcΔt
Rearranging the formula;
c = Q ÷ mΔt
= 677 J ÷ (10 g × 75°C)
= 677 J ÷ 750g°C
= 0.903 J/g°C
= 0.90J/g°C
Thus, the specific heat capacity of Aluminium is 0.90J/g°C
By looking at it and if it is making a single movement it is moving.
The answer is E and F.
Hope this helps!!
