B,c,a,e,g,h,d
i think its the right order.
The equation looks like this:
KBr + AgNO3 —-> KNO3 + AgBr
The products are potassium nitrate and silver bromide

It would be 8 electrons.
(The first energy level can only have 2)

Answer:
0.1159 M
Explanation:
Using the formula below:
CaVa = CbVb
Where;
Ca = concentration/molarity of acid (M)
Cb = concentration/molarity of base (M)
Va = Volume of acid (mL)
Vb = volume of base (mL)
According to this question, the following information were given:
Ca = ?
Cb = 0.2831 M
Va = 26.86 mL
Vb = 11.00 mL
Using CaVa = CbVb
Ca × 26.86 = 0.2831 × 11
26.86Ca = 3.1141
Ca = 3.1141 ÷ 26.86
Ca = 0.1159
The molarity of the acid (H2SO4) solution is 0.1159 M
The electron configuration of a calcium ATOM would be
But, the calcium ION has two electrons less than a calcium atom.
The electron configuration of a calcium ION should be the same as Argon since a calcium ion is missing 2 electrons.
Your answer is
Have an awesome day! :)
