Answer:
(a) Covalent bond. NF₃ (nitrogen trifluoride)
(b) Ionic bond. LiCl (lithium chloride)
Explanation:
<em>(a) N and F</em>
Nitrogen and fluorine are nonmetals, with high and similar electronegativities, so they form covalent bonds, in which they share pairs of electrons to complete the octet in their valence shell. N has 5 valence electrons so it will form 3 covalent bonds while each Cl has 7 valence electrons so it will form 1 covalent bond. As a result, the empirical formula is NF₃ (nitrogen trifluoride).
<em>(b) Li and Cl</em>
Lithium is a metal and Chlorine is a nonmetal. They have different electronegativities so they form an ionic bond, in which Cl gains 1 electron (7 valence e⁻) and Li loses 1 electron (1 valence e⁻). The empirical formula is LiCl (lithium chloride).
Hello!
Data:
P (pressure) = 1 atm
V (volume) = 18.5 L
T (temperature) = 300 K
n (number of mols) = ? (in mol)
R (Gas constant) = 0.082 (atm*L/mol*K)
Apply the data to the Clapeyron equation (ideal gas equation), see:
Note:
If the feedback is to be considered, the closest r
esponse is 0.751 mol Nacl

Except catalyst because catalyst typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
Personally, I do. We use many other creatures for our own good, and I believe that a human life is worth more than that of other creatures.
The indivisibility of an atom was proved wrong and no longer accepted today.
<h3>What is an atom?</h3>
An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons.
Hence, an atom is the smallest particle that takes part in chemical reactions.
