Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue 
reacts with water to produce pink colored complex.
In this complex, 
ion forms an octahedral complex with six 
ligands.
As is a weak field ligand therefore ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is 
with total three unpaired electrons.
Answer:
a) 0.61 mol
Explanation:
165.3718 g Rubidium Bromide = 1 mol
100 g Rubidium Bromide = 1/165.3718 x 100
= 0.61 mol
The block’s average speed : 0.36 m/s
<h3>Further explanation</h3>
Distance is the length traveled by an object within a certain of time .
Average speed = total distance/total amount of time ,
Can be formulated :
ΔD= total distance
Δt= total time
A block is pulled 0.90 m to the right in 2.5 s :
ΔD= total distance = 0.9 m
Δt= total time = 2.5 s
The block’s average speed :
Answer:
See below!
Explanation:
For the chemical formula, you need to have enough of each atom so that the charge is zero.
Aluminum has a +3 charge, and fluorine has a -1 charge. Since the charge has to be zero, you need three fluorines, giving you AlF₃.
Barium has a +2 charge, and oxygen has a -2 charge. Since the charges are equal in magnitude but opposite in sign, you only need one of each atom giving you BaO.
The name of the ionic compound will be the metal and then the nonmetal. When putting the nonmetal in, change the ending to "-ide". For example "chlorine" would be "chloride.
CaCl₂ ==> calcium chloride
Ga₂S₃ ==> gallium sulfide
K₃N ==> potassium nitride
AlF₃ ==> aluminum fluoride
BaO ==> barium oxide
<h2>Hey there!</h2>
<h3>The correct option is (A) It has a partial negative charge on oxygen and a partial positive charge on hydrogen.</h3>
<h3>☆ Explanation:</h3>
¤ As water has the ability to form hydrogen bonds which makes it an excellent solvent.
¤ For this ability of water it can dissolve many different kinds of molecules.
