Because the bond order in an oxygen gas is shown to be equal to 2, the idea furthermore supports the prediction of the molecular orbital theory in the paramagnetism of oxygen gas. This theory is primarily used when electrons are not included in the individual bonds for determining molecular structure.
Astatine. Because it has the smaller shell of electrons. I believe
The measure of the quantity of heat exchanged.
Uses many different units of measurements.
1. Rocks near mid-ocean ridge were younger than rock near trenches
2.Matching bands of magnetic rocks were found on either side the mid-ocean ridge; bands like tree rings - record changes in earth's magnetic field over time
3. Earthquake data showed oceanic crust is sinking on to the mantle at trenches
Answer:
Sodium dihydrogenphosphate = NaH₂PO₄
Sodium monohydrogenphosphate = Na₂HPO₄
Explanation:
A buffer solution is a solution is a solution that resists changes to its oH when a little quantity of strong acid or strong base is added to it.
They are solutions of weak acids or weak bases and their salts known as conjugate base or conjugate acids respectively for the weak acids and weak bases.
For example, a solution of the weak acid ethanoic acid and its salt or conjugate base, sodium ethanoate serves as a buffer solution.
In biochemical experiments, where the pH of the reaction medium is kept as constant and as close as possible to that of the internal environment, buffer solutions are widely used. One of the commonly used buffers is the phosphate buffer. The phosphate buffer consists of the acid salts sodium dihydrogenphosphate and sodium monohydrogenphosphate. Sodium dihydrogenphosphate serves as the weak acid while sodium monohydrogenphosphate serves as the conjugate base.
The formulas of these two compounds are given below:
Sodium dihydrogenphosphate = NaH₂PO₄
Sodium monohydrogenphosphate = Na₂HPO₄
