Density
What is the equation to find Density?
D= Mass / Volume
Fe+ Cl2→ FeCl3
2 Fe+3 Cl2 → 2 FeCl3
What do we use to make lewis dot diagrams?
Valence electrons
Electronegativity general increases as we move ... across the periodic table
Left to right.
It is the key feature of an Ionic bind
electrons are transfered
It is the density of a chunk of gold that weighs 23.5 grams and occupies a volume of 11 mL
What is 2.136
C2H4 + O2 → CO2 + H2O
1 C2H4 +3 O2 → 2 CO2 +2 H2O
It is the type of bond formed between Li and Cl.
3.0-1.0=2.0 ionic
It is the fourth most abundant element occupying 78% of the earth's atmosphere.
Nitrogen
This type of bond occurs when there is equal sharing (between the two atoms) of the electrons in the bond. Molecules such as Cl2, H2 and F2 are the usual examples.
Nonpolar Covalent
It is the density of 450 g of zinc and 43.3 mL
What is 10.3926 g/mL
C7H16 + O2 → CO2 + H2O
1 C7H16 +11 O2 → 7 CO2 +8 H2O
It is the type of bond formed between C and O.
3.5-2.5=1.0 Polar covalent
It is the element that is used to propel rockets in what state?
liquid oxygen
It is the information that the type of bond it gives us?
the strength of the bond, the future behaviors
If the Volume of Copper is 3024.0 g and the density is 2.347 g/mL what is the Volume?
what is 1288.453
C2H4 + O2 → CO2 + H2O
1 C2H4 +3 O2 → 2 CO2 +2 H2O
Please draw the lewis dot diagram for Ne
all 8
Plays a vital role in every physiological reaction in the body and is the most abundant element in the universe but not the body. it does make up 18% of the body though
what is Carbon?
It is the key feature of a Covalent bond
electrons are shared
What is the volume of a silver metal that weighs 2500.0 g. The density of the silver is 10.5g/cm3
what is 238cm3
HSiCl3 + H2O → H10Si10O15 + HCl
10 HSiCl3 +15 H2O → 1 H10Si10O15 +30 HCl
Please draw a lewis dot diagram for Ca.
two dots
This element makes up 65% of the human body and is considered the most abundant element within the body.
what is oxygen
It is the type of bond formed from having a change in electronegativity greater than 2.0
1. If the electronegativity difference (usually called ΔEN) is less than 0.5, then the bond is nonpolar covalent.
2. If the ΔEN is between 0.5 and 1.6, the bond is considered polar covalent
3. If the ΔEN is greater than 2.0, then the bond is ionic.
