Explain why transition metals do not have a predictable pattern for the
ionic charges they form.
Answers
Explanation:
Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. In addition, the majority of transition metals are capable of adopting ions with different charges.
The reason why transition metals do not have a predictable pattern should be explained below.
What are transition metals?It comprises many chemical elements that contains valence electrons with respect to the participation in the creation of the chemical bonds. The various transition metals should not lose sufficient electrons for attaining the noble gas electron configuration. The majority of the transition metal should be capable of adopting the ions with the distinct charges.

If a chemist does the reaction and produces 3.5 moles of aluminum oxide, how many moles of O2 were used in the reaction?
Answers
The Stochiometric coefficient between o2 and Al2O3 is 3:2
You have 3.5 moles of aluminum oxide so you have a simple equation you can solve
3.5*3=2x
According to the stoichiometry and given chemical equation ,5.25 moles of oxygen are used in the reaction to produce 3.5 moles of aluminium oxide.
What is stoichiometry?It is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.
In the given chemical equation, 3 mole of oxygen produces 2 moles of aluminium oxide.
Therefore for 3.5 moles of of aluminium oxide to be produced 3.5×3/2= 5.25 moles of oxygen are used.
Thus, 5.25 moles of oxygen were used in the reaction to produce 3.5 moles of aluminium oxide.

A boxed 10 kg computer monitor is dragged by friction 5.5 m up along the moving surface of a conveyor belt inclined at an angle of 36.9° above the horizontal. If the monitor’s speed is a constant, how much work is done on the monitor by friction?
Answers
Answer:
324 J
Explanation:
58.84 * 5.5 J = 324 J
I got 58.84 by 10 * 9.8 (gravity) * sin(36.9)
The amount of work done on the monitor by friction is equal to 431 Joules.
Given the following data:
Mass of computer monitor = 10 kgDistance = 5.5 metersAngle of inclination = 36.9°To determine the amount of work done on the monitor by friction:
Mathematically, work done is given by the formula:
[tex]Work\;done = mgdcos\theta[/tex]
Where:
m is the mass of an object.g is the acceleration due to gravity.d is the distance.Substituting the given parameters into the formula, we have;
[tex]Work\;done = 10 \times 9.8 \times 5.5 \times cos(36.9)\\\\Work\;done = 539 \times 0.7997[/tex]
Work energy = 431 Joules.

The reaction equation is given as;
NH₃ + O₂ → N₂ + H₂O
Now, we need to balance the reaction equation;
NH₃ + O₂ → N₂ + H₂O
put the numbers a,b,c and d;
aNH₃ + bO₂ → cN₂ + dH₂O
We need to balance the equation algebraically, ;
Conserving N;
a = 2c
Conserving H;
3a = 2d
Conserving O;
2b = d
Now, let c = 1, a = 2, d = 3 and b = [tex]\frac{3}{2}[/tex]
multiply through by 2;
a = 4, b = 3, c = 2 and d = 6
