How many grams of Cl are in a 38.0-g sample of the chlorofluorocarbon CF2Cl2

Chemistry
1 answer:
Katena32 [7]3 years ago
4 0
The molecular formula of chlorofluorocarbon is CF₂Cl₂ 
Molecular mass of CF₂Cl₂ is 120.9 g/mol
Mass of Cl in 1 mol - 2 x 35.5 = 71 g/mol
in 120.9 g of compound - 71 g of Cl
Therefore in 38 g of sample - 71/120.9 x 38 g of Cl
Mass of Cl in 38 g - 22.31 g of Cl

The melting point of the metal potassium is 63.5c, while that of titanium is 1660c. what explanation can be given for this great
kiruha [24]

The melting point of potassium = 63.5^{0}C

Melting point of titanium = 1660^{0}C

Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.

Atoms share one or more pairs of electrons.<br><br> Options:<br> Ionic Bond or Covalent Bond?
garri49 [273]

Answer:

covalent bonds

Explanation:

ionic transfer of e^- ions formed (charges)

ionic=non-metal+ metal

ex: F+Ca

covalent sharing e^- no true charges

covalent= non-metal+ non-metal

ex: F+P
