Answer:
The correct answer is 4). A total of 8?valence electrons
Explanation:
The argon corresponds to a noble or inert gas, like Helium, and has its complete octet in the last layer.
1. Ph is a figure used to measure the alkalinity or acidity of something. 7 is the neutral figure while lower numbers mean that the thing is more acidic. Higher numbers mean the thing is has more alkaline in it.
2. 7.35 is the ideal Ph of blood.
Answer:
It is called the superior sagittal sinus.
Explanation:
The superior sagittal sinus which is often called the superior longitudinal sinus) is situated in the human head. It is an unpaired region in the human head around the attached margin of the falx cerebri. It main function is to ensure that blood is removed from the lateral parts of the anterior cerebral hemispheres and transferred to the confluence of sinuses. It also has a triangular cross sectional area and with a left/right lateral angles at its junctions. Therefore, The right answer is the the superior sagittal sinus.
Answer:
Please find the definition and example of neutralization reaction below
Explanation:
In chemistry, neutralization reaction is a type of reaction involving a base and an acid to form salt and water. In other words, when an acid and a base comes together chemically to form a salt and water, a neutralization reaction is said to occur.
For example; in a reaction between sodium hydroxide (NaOH) and hydrogen chloride (HCl) as follows:
HCl(aq) + NaOH(aq) → NaCl(s) + H2O(l)
In this neutralization reaction, the HCk is the acid while the NaOH is the base (reactants). For the products, the NaCl is the salt while H2O is water.
