The sigma bonds are formed when orbitals overlap side by side and is related to covalent bond In ethylene the number of sigma bond are 5.
Reason, carbon has four carbon -hydrogen bond which form four sigma bond. The other sigma bond is between carbon=carbon bond thus ethylene has 5 sigma bond
In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Heat required = M * C * (delta T)
= (Mass)*(Specific heat)*(temperature change)
= 250 * 4.18* 52 = 54340Joules.
I solve when unit of specific heat is (J/gC) if have another unit please tell me
Answer:
Metallic Bonding
Explanation:
Conductivity occurs when electrons or ions are free moving. The conductivity in metals is due to electrons being delocalized in a sea of electrons. Metals contain metallic bonding which allows the electrons to freely move.
Malleability happens when adjacent layers of positive ions move relative to one another while being in contact with the sea of electrons from the metallic bonding.
Answer:
0.0821 L•atm/mol•K
Explanation:
The value of the ideal gas can be obtained as follow:
NOTE: We shall use the standard value for each variable. Based on the options given above, we shall use the equivalent units as well.
Pressure (P) = 1 atm
Volume (V) = 22.4 L
Number of mole = 1 mole
Temperature (T) = 273 K
Gas constant (R) =?
PV = nRT
Divide both side by nT
R = PV / nT
R = (1 × 22.4) / (1 × 273)
R = 22.4 / 273
R = 0.0821 L•atm/mol•K
Thus, the ideal gas constant is 0.0821 L•atm/mol•K
