<h2>Iron (Z = 26)</h2>

Explanation:

  • Stellar fusion is the nuclear reaction that occurs in stars.
  • In this reaction, the nuclei build to form heavier elements.
  • Stars fuse elements of lighter ones to heavier ones
  • This fusion reaction occurs in their cores.
  • During this process, a lot of energy is released.
  • This process is also known as stellar nucleosynthesis as there is a synthesis of the different nucleus.
  • Stellar fusion produces lighter elements of many types including iron(Fe) and nickel(Ni) in many of the giant stars.
  • These elements remain trapped in the cores of stars.

When two moles of ethane react completely with oxygen, how many moles of carbon dioxide will be produced?A. 2.B. 4.C. 8.D. Unkno
babymother [125]

Answer:

Option B.

Explanation:

As any reaction of combustion, the O₂ is a reactant and the products are CO₂ and H₂O. Combustion reaction for ethane is:

2C₂H₆  +  7O₂   →   4CO₂  +  6H₂O

So 2 moles of ethane react with 7 moles of oxygen to make 4 moles of dioxide and 6 moles of water.

Then 2 moles of ethane will produce 4 moles of CO₂

3. When the hydronium ion concentration of a solution is 1x10-4 M, What
rewona [7]

Answer:

pH = 4

Solution is acidic

Explanation:

Given data;

Hydronium ion concentration = 1 × 10⁻⁴ M

pH of solution = ?

Solution:

pH = -log [H₃O⁺]

pH = -log [ 1 × 10⁻⁴ ]

pH =  4

According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.

Explain why BH3 is trigonal planar and NH3 is trigonal pyramidal.
Troyanec [42]

Answer:o It is important to realise that mixing will be small unless there are electrons in the 4a1 LUMO, this is why NH3 is pyramidal while BH3 is planar! ... This mixing is very strong and stabilises the 3a1 MO substantially and hence NH3 is trigonal pyramidal and not planar.
