Answer: Pt(Cl)2(NH3)2
Explanation:
In the formation of the complex, the oxidation number of platinum is plus two (+2) and two chloride ions cancel it out by their oxidation number of -1 each. Hence the complex has an overall charge of zero. It is thus neutral with no charge attached to its formula.
Lithium Hydroxide (LiOH) is an Arrhenius base
Answer:
613 mg
Explanation:

Number of fargday's 
Here, I = 9.20 A
t = 10.5 min
= 10.5 x 60 seconds
So, 

= 0.0208 F
Here, 2e, 2F
2F = 1 mol of Ni

1 mol = 59 gm of Ni
0.0104 mol = 59 x0.0104 gm Ni
= 0.613 gm Ni
= (0.613 x 1000 ) mg of Ni
= 613 mg of Ni
Answer:
liquid and solid
Explanation:
Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.
This discovery took place with the help of artificial intelligence of today's world which is transforming the world day by day.
The State is considered to be true as it is thermodynamically stable state of the matter.
