What is the density of a piece of plastic weighing 5.22 grams while the volume is 7.07 milliliters |
.738 grams per milliliter |
|
|
Will a plastic weighing .738 grams per milligram sink or float in water |
It floats as its density is less than water |
|
|
If a second piece of plastic were found in show to have the mass of 10.44 grams in a volume of 10.62 milliliters which of the following can be said |
They are different types for different reasons |
|
|
If a certain law has a volume of 5.38 milliliters and density of 12.3 grams per milliliter then what would be the its mass |
66.2 grams |

Elements on the left side of the periodic tables are what sort |
Metals |
|
|
The family number of main group elements corresponds to the |
Valence electron number |
|
|
From the formula alone it is possible to tell whether a compound is ionic based on having |
At least one metal and one nonmetal represented |
|
|
From the formula alone it is possible to tell whether a compound is covalent based on having |
No metals present |
|
|
Each covalent bond is characterized by having |
A pair of electrons |
|
|
The name of this compound: FEI2 is |
Iron (2) iodine |
|
|
Negatively charged atoms are more properly called |
Anions |
|
|
Ionic and covalent compounds are different from each other because unlike covalent compounds ionic compounds |
Conduct an electrical current |
|
|
These atoms are both electronegative, so tell us that a molecule containing them may be polar |
O and N |
|
|
The rules by which electron repulsion determine molecular shape is |
VSEPR theory |
|
|
Some of the valence electrons around central atoms and molecules, such as O or N, are shared while others are not. Such electrons (those not shared) are called |
non bonding electrons |
|
|
Electronegativity matters because it causes the following in compounds |
Polarity |
|
|
The current name for NO is |
Nitrogen oxide |
|
|
The name of the compound indicated by the formula N2O5 is |
Dinitrogen pentoxide |
|
|
Hydrogen bonds are responsible for which of the following |
DNA structure |
|
|
Understanding properties of solubility melting and boiling points DNA structure ice crystal patterns and snowflakes in others requiring knowing about |
Hydrogen bonds |
|
|
The molecular shape of the methane molecule, CH4, is |
Tetrahedral |
|
|
Because oxygen has to nonbonding electrons water h2o must have this structure |
Bent |
|
|
Nearby water molecules interact with others by way of someone weak force is called |
H bonds |
|
|
Compounds containing only C's and H's possessed this property and not the others |
Non polarity |
|
|
Small nonpolar compounds are gases at room temperatures, but as they get larger they are more likely to be liquids and then solids. This is due to this kind of intermolecular interaction |
Dispersion forces |
|
|
The fact that most atoms in molecules have four pairs of valence electrons around them is |
The octet rule |
|
|
Polar molecules that do not have the ability to form hydrogen bonds interact with each other by way of this form of intermolecular interaction |
Dipole dipole interactions |
|
|
Matters that some atoms are electronegative because this greatly influences |
All of the above bond polarity and molecular shape and molecular interactions and properties of their compounds |
|
|
Covalent molecules show this characteristics kind of interactions among their atoms |
Covalent bonds |
|
|
Formaldehyde contains a central carbon atom join covalently to one option by way of double bond and two hydrogens with the single bond each. Therefore, formaldehyde displays the following molecular shape |
Trigonal planar |
