when hydrochloric acid is added to a potassium hydroxide solution, the acid and base would react to form salt(potassium chloride) and water
Chemical Formula:
HCl(aq) +KOH(aq) ---> KCl (aq) + H20 (l)
<span>They don't use opinion based research.
It is always objective.
They utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation</span>
2. Hypothesis
3. Experimentation
4. Interpretation of data
5. Evaluating the data
6. Passing and recording the data
<span>These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.<span>

Answer:
D) energy required to remove a valence electron
Explanation:
Ionization energy can be defined as the atom's ability to and the energy required to remove a valence electron. Ionization energy increases up a group and to the right along a period. So helium has the highest first Ionization energy meaning that it is very hard to remove an electron from helium because octet is already complete.
Hello!
The approximate bond angle around the central carbon atom in acrolein is
120°
The structure of acrolein is shown in the figure below. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).
Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°.
Have a nice day!
Answer:
b. The nitrogen atom shares one valence electron with each iodine atom, which also shares one valence electron each with the nitrogen atom.
Explanation:
The formula of nitrogen triiodide is NI3. In this compound, the nitrogen atom shares one valence electron with each chlorine atom which in turn also shares a valence electron with nitrogen.
Recall that covalent bonding involves a sharing of <u>valence </u> electrons. Transfer of electrons is typical of ionic bonds between a metal and a nonmetal. nitrogen and iodine are nonmetals hence they bond covalently.
Hence, the formation of NI3 leaves three lone pairs on each chlorine atom and one lone pair on the nitrogen atom.
