Answer: The formulas for the ionic compounds are:
a)
b)
c)
d)
Explanation:
Determining the formulas for ionic compounds relies on:
The criss-cross method, wherein the oxidation states of ions are exchanged, forming the subscripts of the respective ions, resulting in a neutral compound.
(a) Copper bromide is formed based on the 
ion.
(b) Manganese oxide originates from the inclusion of the 
ion.
(c)Mercury iodide contains the 
(d) Magnesium phosphate includes the 
The dimension is 3.00 cm.
Explanation: Absorbance can be articulated using Beer-Lambert's law: A = ε*b*c, where ε is a characteristic constant for each compound, b is the path length of light, and c is the concentration of the solution. To align the absorbance values for both solutions since they must be equal... **Substituting values and solving gives b = 3.00 cm.
43.62m
Clarification:
Given details:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell =?
Solution:
This bell possesses potential energy, which signifies energy at rest due to its positional context.
Potential energy = m g h
where m denotes the mass of the object
g indicates gravity's acceleration
and h stands for the height of the object
Here, we need to isolate for h.
g = 9.8m/s²
Insert the variables;
8550 = 20 x 9.8 x h
As a result, h = 43.62m

Potential energy
Answer:
334 J/g
Explanation:
The relevant data provided in the question are as follows:
Mass (m) = 1 g
Specific heat of Fusion (Hf) = 334 J/g
Heat (Q) =?
By applying the formula Q = m·Hf, we can calculate the heat released:
Q = m·Hf
Q = 1 x 334
Q = 334 J
Thus, the total heat released amounts to 334 J.
