Answer : The heat energy needed would be, 6486.5125 J
Explanation :
To calculate the change in temperature, we use the equation:
where,
q = heat needed = ?
m = mass of aluminum = 223 g
c = specific heat capacity of aluminum = 
= change in temperature
= initial temperature = 
= final temperature = 
Putting values in above equation, we get:
Therefore, the heat energy needed would be, 6486.5125 J
The region where an electron is most likely to be is called an orbital
Answer:
I. N−3
III. F−1
Explanation:
A positive charge indicates a loss of electrons whereas a negative charge denotes electron gain.
For two species to have the same electron configuration, they must have the same number of electrons within their atomic space.
So, the solution to this problem will be two species with the same number of electrons:
Nitrogen in neutral state has 7 electrons, on gaining 3 the electrons becomes 10
Fluorine in neutral state has 9 electrons, on gaining 1 more, it will have 10 electrons.
Ni2(SO4) 3 is named Nickel(lll) sulfate. Hope it helps
