Which is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle?
Rama09 [41]

Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

<h3>What do you mean by the nuclear fusion ?</h3>

Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.

The main advantage of nuclear fusion is it is safe source for the generation of electricity.

Characteristics of nuclear fusion -:

  • The main characteristic of nuclear fusion is that it involves formation of a singular particle from two or more atoms.

  • Unlike nuclear fission, nuclear fusion is common in nature- just hard to recreate.

  • Nuclear fusion typically produces few radioactive particles .

  • Fusion works by applying a great deal of pressure to overcome .

Hence ,Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

How many grams of Al(no2)3 should be added to 1.3L of water to prepare a 2.0M solution
Virty [35]

Answer: 429 grams of Al(NO_2)_3  should be added to 1.3 L of water to prepare 2.0 M solution

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute Al(NO_2)_3 = \frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{165g/mol} 

V_s = volume of solution in Liters  

Now put all the given values in the formula of molarity, we get

2.0M=\frac{xg}{165g/mol\times 1.3L}

x=429g

Therefore, 429 grams of Al(NO_2)_3  should be added to 1.3 L of water to prepare 2.0 M solution
