If 568 ml of O2, gas at 49°C is cooled and now occupies a volume of 399.5 mL, then what is the new temperature in K? Don't forget to use Kelvins and round to ones place
(so you don't have to worry about using scientific notation).

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
