Answer:

My name is Isaac Newton and I am a scientist. I am known as one of the most important scientists in history. I was born in Woolsthorpe, England on January 4, 1643. My father, a farmer who was also named Isaac Newton, had died three months before my birth. My mother remarried when I was three years old and left me in the care of my grandparents.

Is a solution in which (OH) = 1.0 10-1M acidic, basic, or neutral?

astra-53 [7]

Answer:

The pH is 13,00 and the solution is basic.

Explanation:

<em> </em>The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = -log (H 30+)

Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:

[H3O ^ +]x [OH ^ -] = 1x 10 ^ -14

[H3O ^ +]x [1.0 10-1]=1x 10 ^ -14

[H3O ^ +]= 1x 10 ^ -14/1.0 10-1M= <em>1.0 10-13 M</em>

pH = -log (H 30+)= -log (1.0 10-13 M)= <em>13, 00</em>

As the pH value is higher than 7, it corresponds to a basic substance.

The highest energy occupied molecular orbital in the C-C bond of the C2 molecule is?

Butoxors [25]

The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.

<h3>What is Molecular Orbital Theory?</h3>

According to this theory,

Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
The shape of molecular orbitals formed depends on the type of atomic orbitals combined
Only atomic orbitals having comparable energies and the same orientation can intermix
Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
Bonding M.O. is represented by $\sigma, \pi, \delta$ while Antibonding M.O. is represented by $\sigma^*, \pi^*, \delta^*\\$
