Here is the BALANCED reaction eq'n.
2H2(g) + O2(g) = 2H2O(l)
The prefix number are the Molar Ratios 2:1::2
So oxygen is ONE(1) mole
Hence hydrogen is TWO(2) moles
It produces TWO(2) moles of water.
Bromine, like Fluorine and Chlorine, is an Halogen. Halogens gain an electron to become X^(-) anion.
'X' being the general symbol for an halogen.
NO!!! It is TWO(2) ionic bonds.
CaCl2 = Ca^(2+) + Cl^(-) + Cl^(-)
Definitely IONIC. Because if there were no ions present, then charge would not move, hence no electric flow.
Molecules formed by covalent bonding include water (H₂O), methane (CH₄), and oxygen (O₂), where atoms share electrons to achieve a stable configuration.
It is neither!!!!!
Neon is monatomic gas. That is a gas that exists as single uncombined atoms.
Ionic or Covalent means the type of bonding betyween atoms.
There are a couple of things that cause specific lines to appear in a line spectrum. Two of these things are density and wavelength.
Sodium chloride (NaCl) found in the home as TAble Salt.
Also
Sodium bi-carbonate (NaHCO3) as Baking #Poder.
Sodium Carbonate (Na2CO3) as washing sode/ soda crystals.
Sodium stearate ( NaOOC(CH2)16CH3) as soap.
NO!!!
Because they are both positive ions , they will REPEL each other.
An ionic compound has both positive and negative ions. ~Thet attract each other.
NB
Think of the North and South poles of a magnet. Two north poles facing each other REPEL . A borth and South pole facing each other ATTRACT.
By sharing electrons.
The analogy is like two people linking arms.
Both CATIONS (M^([n]+)) and ANIONS (X^([n]-)) are needed.
It has a high melting point.
It does NOT conduct electricity as a solid, but does conduct electricity, when liquid or in solution.
The bonding is ionic (NOT Covalent)
Forms a giant crystalline lattice.
NO!!!! It a covalent bond.
Any one Carbon atom makes four single covalent bonds to four adjacent carbon atoms. The structure is referred to as ADAMANTINE.
Diamond is an ALLOTROPE of Carbon. Othe carbon allotropes are graphite(soot) and Buckminster Fullerene(Footballene)
To indicate the oxidation number using Roman numerals.
e.g.
Ferric oxide or ferrous oxide /??? Which
Ferric oxide (Fe(II)O).
Ferrous oxide (Fe2(III)O3).
or
Potassium permasnganate KMnO4 The manganese is (+7) . hence
KMn(VII)O4
LiO DOES not exist.
Lithium oxide has the formula 'Li2O'.
H2, CH4, Cl2, C2H2, CO2, O2 were all non polar atoms because they all were not lone pairs (meaning that there were no one dots).
Also don't write this down but look at all the bonds. They all have 2 or 4 and not 3 or 5. For example: Cl2 and not Cl3.
Fe2O3 is ' iron(III) oxide' . Archaically and commerically it goes by the name of 'ferric oxide' or iron ore.
no it is covalent because it is between two nonmetals but a ionic is between a metal and nonmetal
No, because part of the definition of a compound is a requirement for lack of net electric charge, but any ion by must have a net electric charge.
YES!!!
2Rb(s) + Br2(l) = 2RbBr(s)
It is similar to the sodium / chlorine reaction, and compound.
YES!!! THey form calcium oxide, other wise known as 'lime' or 'quicklime'.
