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
Like dissolves like
so water is polar
CCl4 is nonpolar
LiCl is polar
CH4 is nonpolar
PCl6 is nonpolar
so LiCl would dissolve
First let's look at the photosynthesis equation:
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
We know that:
CO₂ is carbon dioxide
H₂O is water
<span>C₆H₁₂O₆ is glucose
</span><span>O₂ is oxygen
</span>
We also know that the left side of the reaction is the reactants (which gets used up), and the right side is what is produced.
Now, we can look at each of the choices to see which one matches the equation:
We can eliminate the last two choices automatically because there is no hydrogen atoms present on either side.
The second one is not correct because oxygen is a product, not a reactant.
Therefore, the answer is the first one because carbon dioxide is a reactant, and oxygen is a product.
Answer:
Explanation:
Percent composition is percentage by the mass of element present in the compound.
Given , Mass of sulfur= 32.1 amu
Mass of oxygen = 16.0 amu
Mass of sulfur trioxide 
= 32.1 amu + 3*16.0 amu = 80.1 amu
Answer:
yes that is true.Because they are ions.oppositely chared ions attract each other
