Two dangerous elements can form a compound that is edible known as "NaCl salt".
<u>Explanation:</u>
Sodium and chlorine are two very dangerous elements. As the reaction between sodium and water is extremely violent and chlorine is a very toxic gas. But combination of these elements result into a harmless product with unique properties like it is edible and dissolves without exploding in water.
In sodium chloride reaction the atoms of sodium interact with chlorine atoms. Sodium will donate an electron (by becoming positively charged) to acceptor chlorine (which become negatively charged) as given in following reaction

As sodium and chlorine are very keen to achieve noble gas configuration by completing an octet on donating and accepting an electron respectively.

Because you multiply 8x1.5 and you get the answer.
Answer:
Depends on the capacity of battery. Mostly our phones flashlight can be used up to 8 to 10hrs continuosly
Explanation:
Capacity of the battery is level to which battery is charged, & amount of current drawn by the flashlight, you can calculate the answer yourself if u know the capacity of that light.
Moreover you can calculate this by using equation,
E =Pt
So, for time
t=E/P
Batteries are rated in Amp hours, like 10 amp hours will supply us 1 amp for 10 hours
2 amps will give us 5 hours
