Answer:
ahhh....Double displacement reaction or precipitation reaction.(both are correct im not guessing)
Taking into account the reaction stoichiometry, 51.84 grams of HCl is required to react completely with 12.8 g of aluminum to produce aluminum chloride and hydrogen gas.
In first place, the balanced reaction is:
2 Al + 6 HCl → 2 AlCl₃ + 3 H₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
The molar mass of the compounds is:
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
The following rule of three can be applied: If by reaction stoichiometry 54 grams of Al react with 218.7 grams of HCl, 12.8 grams of Al react with how much mass of HCl?
mass of HCl= 51.84 grams
Finally, 51.84 grams of HCl is required to react completely with 12.8 g of aluminum to produce aluminum chloride and hydrogen gas.

Answer : The correct option is,
Explanation :
Electronic configuration : It is defined as the arrangement of the electrons of an atom in an atomic orbital.
The given element is, nitrogen.
The nitrogen element belongs to group 15 and the atomic number of nitrogen is 7.
As we know that the number of electrons is equal to the number of atomic number.
The number of electrons present in nitrogen = 7
Thus, the electronic configuration of nitrogen is,
1s22s22p3 considering N is the third element in the 2nd P sublevel
THANK YOU
Alright, so to do this, you need to know the name of the elements and compounds, since all of these are ionic compounds which have different naming rules than covalent compounds, all you need is a periodic table and an ion chart. I'll do the first column.
A. Calcium Nitrate
B. Potassium Hydroxide
C. Magnesium Carbonate.
I also am including a picture of an ion chart that include almost all of the ions to help you with the rest of them.
All substitutions must be limited to the same element.
An atom must be identical in size.
An atom must be similar in size.
The substituting atom must be from the same period.
The substituting atom must be from the same group.
Ans: C) and E)
A solid solution is essentially a multicomponent system which is composed of a mixture of two or more elements sharing the same crystal lattice. Alloys are solid solutions.
The requirement for one type of atom to substitute for another in a solid solution are two fold
1) The atom must be similar in size
2) The substituting atom must be from the same group.
B Attach muscle to bone
C Attach bone to bone
DAttach bone to blood vessels
