Answer:

Steel is a metallic bond

Propane is a covalent bond

Calcium Chloride is an Ionic Bond

Water is a covalent bond

Explanation:

ence a material's properties, identify each of the , ionic, covalent, or metallic bonds

Ionic Bonds are where the extra outer electron of one atom transfers to the other atom.

Covalent Bonds are where the outer electron of one atom takes the open path to the nucleus (negative valance) of a 2nd atom.

Metallic Bonds are formed from the attraction between free electrons and fixed positively charged metallic atoms. Metallic bonds extend over the entire molecular structure.

Substance                  Properties

Steel                           Conducts electricity as solid and liquid

Propane                      Low melting point

Calcium Chloride       Conducts electricity when dissolved in water

Water                          Solid form is brittle, melts at 0C

Steel is an alloy of carbon, iron and other things

Propane = C3H8 C4- H+

Calcium Chloride  = CaCl2 = Ca2+ Cl-

Water = H2O = OH- and H+

Can a electron be found in an exact spot within a atom
goldenfox [79]

Answer:

Electrons are located in an electron cloud, which is the area surrounding the nucleus of the atom. There is usually a higher probability of finding an electron closer to to the nucleus of an atom.

denis23 [38]

Answer:

The maximum amount of solute that dissolves in a given amount of solvent and forms a stable solution is called the solubility of the solute

Explanation:

The maximum amount of solute that could be dissolved in a given amount of solvent is the solubility of the solute. It is the saturated solution's concentration from where a saturated solution can be defined as the one which already contains the maximum quantity of dissolved solute at a specified temperature, while an unsaturated solution is one with a capacity to dissolve more solutes

A reaction produces 74.10 g Ca(OH)2 after 56.08 g CaO is added to 36.04 g H2O. How should the difference in the masses of reacta
melomori [17]
Cao +  H2O  ---->Ca(OH)2
Calculate   the  number  of  each   reactant  and  the  moles  of  the  product
that  is
moles = mass/molar mass
The  moles  of  CaO=  56.08g/  56.08g/mol(molar  mass  of  Cao)=  1mole
the  moles  of  water=  36.04 g/18  g/mol=  2.002moles
The   moles  of Ca (OH)2=74.10g/74.093g/mol= 1mole

 The  mass  of differences  of  reactant  and  product  can   be  therefore 
 explained  as 
 1  mole   of  Cao  reacted  completely   with   1  mole   H2O  to  produce  1 mole  of  Ca(OH)2. The  mass  of  water   was  in  excess  while  that  of  CaO  was  limited

State the periodic law, and explain its relation to electron configuration. (Use Na and K in your explanation.)
mina [271]

Answer:

Explanation:

The period law state that when elements are listed in order of their atomic numbers, the elements fall into recurring groups, so that there is a recurrence of similar properties at regular intervals.

Na and K in the periodic table fall into the same group, this is because they both have one electrons in their outermost shell.

Na 11 -1s2 2s2 2p6 3s1

K 19 - 1s2 2s2 2p6 3s2 3p6 4s1

They share similar chemical and physical properties. Na and K are very reactive metals, they can loose/donate their outermost electron to non metals in other to attain stable octet state.

The form ionic compound when they react with non metals.
