Convert 2330 mL to the unit dm3.

Chemistry
1 answer:
Lynna [10]3 years ago
5 0
If 1 mL = 0.001 dm3, then we have a given of 2330 mL to be converted to a dm3 unit; we can solve this by doing;

2330 mL x 0.001 dm3 / 1 mL = 2.33 dm3

Therefore, 2330 mL is equivalent to 2.33 dm3. This was solved by multiplying 2330 to 0.001 and cancelling out the mL units, then used dm3 unit as the problem required at first.

If an ultraviolet photon has a wavelength of 77.8 nm calculate the energy of one mole ultraviolet photon.
DerKrebs [107]

Answer:

Explanation:

E = (hc)/(λ)

E = (6.624x10^(-27))Js x ((3×10^8)ms^(-1)) /

(77.8x10^(-9)m)

E = 2.55 x 10^(-11) J

Atomic number and the number of protons are the same...
Neutrons = Mass number - number of protons
Electrons are same # unless there is a charge 
The whole number you see on the periodic table is the atomic number of the element which is also same as the number of protons

1) carbon - 14  ;  Mass number = 14 , Protons = 6 , Neutrons = 14 - 6 = 8 
                                Electrons = 6 

2) Lead - 208  ; Mass # = 208 , Protons = 82 , Neutrons = 208 - 82 = 126
                          Electrons = 82

3) Uranium - 239 ; Mass # = 239  , Protons  =  92,Neutrons = 239 - 92 = 147
                                 Electrons =  92

4) Uranium - 238  ; Mass # = 238 , Protons = 92 , Neutrons = 238 - 92 = 146
                                   
Electrons = 92 

5) Tin - 118  ; Mass # = 118 , Protons = 50 , Neutrons = 118 - 50 = 68
                         Electrons = 50

Ionic bonds are formed when valence electrons are _____ between ____ to form ____
Anastaziya [24]

Answer: transferred, atoms , ions

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.

For formation of an ionic compound, the metal lose electrons to form positively charged ions called as cations and non metals gain electrons to form negatively charged ions called as anions.

For example:

Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.

[Na^+]=1s^22s^22p^63s^0

Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.

[Cl^-]=1s^22s^22p^63s^23p^6
