Answer:
The answer to your question is below
Explanation:
Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.
Kind of elements Difference of electronegativity Bond
a) MgO Metal - Nonmetal 3.44 - 1.31 = 2.13 Ionic
b) SrCl₂ Metal -Nonmetal 3.16 - 0.95 = 2.21 Ionic
c) O₃ Nonmetal- Nonmetal 3.44 - 3.44 = 0 Covalent
d) CH₄O Nonmetal-Nonmetal 3.44 - 2.55 = 0.89 Covalent
Carbon, Hydrogen and oxygen are nonmetals
2) Silver coins can conduct electricity.
Static electricity is the buildup of electric charges on surface of an object.
static electrical charges remain on the surface of the object until they bleed off to the ground or until they get quickly neutralised by a discharge.
Hello!
The balanced chemical equation for the oxidation of diamonds is the following one:
C(s) + O₂(g) → CO₂(g)
As simple as that! You see, Diamonds are an allotropic form of pure carbon. Allotropic forms are different arrangements of atoms. In graphite, the C atoms are arranged in layers like paper sheets, and in diamond, the C atoms are arranged in a tetrahedral structure, which gives them their hardness and their thermal and electrical properties. Burning diamonds would be the same as burning elemental carbon and the chemical equation is the one shown before.
Have a nice day!
Hypothesis, experiment, conclusion<span />
<em>What volume do 5 moles of a gas occupy at 28 ° C and 3 atm of pressure?</em>
<em />
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
n= 5 moles
T=28 +273=301 K
P=3 atm
The volume of the gas :
