Answer:
at the beginning:
pH = 0.745
Explanation:
HCl is a strong acid, so:
0.18 M 0.18 0.18.....equilibrium
before base is added:
∴ [ H3O+ ] ≅ <em>C </em>HCl = 0.18 M
⇒ pH = - Log [ H3O+ ] = - Log ( 0.18 )
⇒ pH = 0.745
Answer:
Name of the compound is Nitrogen triiodide.
Explanation:
According to the IUPAC rules, to naming of the compound the following formula can be applied.
Prefix + Name of first element + Base name element of second element + Suffix.
The given compound - 
Name of first element- Nitrogen
Base name element of second element - Iodine
Suffix = 3 = tri
Here, iodine is in ionic form therefore, it becomes iodide. and then suffix will be added in front of the halogen.
Therefore, name of the compound will be Nitrogen triiodide..
Would that be mass times volume?
<h3><u>Answer</u>;</h3>
D. All polysaccharides are made up of carbon, hydrogen, and oxygen.
<h3><u>Explanation</u>;</h3>
- A polysaccharide is a large molecule made of many monomers called monosaccharides such as glucose, galactose, fructose, etc.
- Polysaccharides can be homopolysaccharides, where all monosaccharides are the same or heteropolysaccharide in which the monosaccharides vary.
- They may be linear, where a molecule of polysaccharides has straight chain of monosaccharides, or branched polysaccharides in which a chain has arms.
- <em><u>All polysaccharides contain oxygen, hydrogen and carbon atoms like all the carbohydrates.</u></em>
