Answer:
The sp³ orbital hybridization has 25% s-character and 75% p-character.
Explanation:
Hybridization refers to the process of mixing of a given number atomic orbitals to form equal number of new hybrid orbitals. The three types of hybrid orbitals are sp³, sp² and sp.
The<u> four sp³ hybridized orbitals</u> are formed by the mixing of <u>one s orbital and three p orbitals.</u>
Thus s-character in a sp³ hybridized orbital = (1÷4)×100 = 25%
and p-character in a sp³ hybridized orbital = (3÷4)×100 = 75%
<u>Therefore, the sp³ orbital hybridization has 25% s-character and 75% p-character.</u>
Regulates the volume and pH of the internal environment. The human excretory system maintains homeostasis by removing metabolic waste such as water, salt and metabolite concentrations in the blood.
Answer:
8.77 kilo Joules will be the total amount of heat required for both the heating and the vaporizing.
Explanation:
Moles of ethanol of ethanol = 0.200 mol
Heat required to heat 0.200 moles of ethanol = Q = 1.05 kJ
Enthalpy of vaporization of ethanol = 
Heat required to vaporize 0.200 moles of ethanol = Q'
Total heat required to fore heating and the vaporizing :
= Q + Q' = 1.05 kJ + 7.72 kJ = 8.77 kJ
8.77 kilo Joules will be the total amount of heat required for both the heating and the vaporizing.
O₂(g) as a reactant
<h3>Further explanation</h3>
In chemical reactions, there is a reaction between reagents and products
Reaction:
aA + bB ⇒ cC
Substances A and B are called a reactants
Substance C is called a product
In the above reaction:
- Reactants: C, O₂ and CO
- Products: CO and CO₂
CO functions as a product in the first reaction and functions as a reactant in the second reaction
In the final chemical equation :
CO(g)+30₂(g) → CO₂(g)
O₂ is on the left so it is called the reactant
Answer:
Ionic Bond
Explanation:
The bond between metals and non-metals is an ionic bond. This is due to the large difference in electronegativity between the non-metal and metal. Metals give up electrons easily, so they will have lower electronegativities. Non-metals can easily gain electrons, so they have high electronegativities. If you look at valence electrons, they will extensively/exclusively surround the non-metal.
