I think 8, because you have to end up with a balanced equation.
Answer: -
Chemical formula of sodium hydroxide = NaOH
Chemical formula of Nickel (II) Chloride = NiCl₂
The product is a solid compound of Ni²⁺ ions and hydroxide ions.
So the compound formed is Nickel (II) Hydroxide.
Chemical formula of Nickel (II) Hydroxide = Ni(OH)₂.
Since a double displacement reaction occurs, the other product should be NaCl.
The balanced chemical molecular equation for the reaction is thus
NiCl₂ + NaOH → Ni(OH)₂ + NaCl.

<u><em>I HOPE IT WILL BE YOUR ANSWER:</em></u>
Explanation:
As given
60 min = 50 gm (1)
then we know half-life mean half amount decay time
so we can write as the half of 200 is 100 gm hence
T 1/2 = 100 (2)
solving these two equation by cross multiplication we will get
T 1/2 = 120 min

Answer:
<h3>The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms". ... The number of carbon atoms may be considered as the size of the alkane.</h3>
