I would say c-gas because they float around and spread
Answer:
600K
Explanation:
PV=nRT
T=PV/nR
= 1.6atm* 15.0L/ 0.5mol*0.0821LatmK^-1mol^-1
=600K
<h3>1. what is a typical characteristic of an ionic compound?</h3><h3>Answer:</h3>
Option-D : The ionic compound has a high melting point.
<h3>Explanation:</h3>
Ionic compounds are made up of positive ions called cations and negative ions called as anions. Cations are formed when an atom or group of atoms looses one or more electrons while, anion is formed when an atom or group of atoms gains electrons.
The two opposite ions formed interact through electrostatic interactions and form one of the strongest intramolecular bonding called ionic bonding. It requires very high energy to separate these ions from each other in solid form.
Examples: Melting Point of NaCl = 801 °C
Melting Point of MgCl₂ = 714 °C
Melting Point of CaCO₃ = 825 °C

<h3>2. what is shown by the structural formula of a molecule?</h3><h3>Answer:</h3>
Option-A : The arrangement of bonded atoms.
<h3>Explanation:</h3>
Structural formula is the graphical representation of of a chemical formula in either two dimensional or three dimensional space. It helps in depicting the arrangement of atoms or group of atoms in a compound or molecule.
Examples:
Below the attached figure shows the structural formula of Glucose with Chemical formula C₆H₁₂O₆, Sulfuric Acid with Chemical formula H₂SO₄ and Water with Chemical formula H₂O respectively.
Answer:
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
