Each of the following is a noncovalent interaction except a carbon-hydrogen bond. The correct option is B.
Explanation:
Non covalent interaction: is the sharing of electron as weak bonds between hydrogen and other atom. Non covalent interaction have large roles in the maintenance of structures of biomolecules as proteins. In biological processes many times a transient bonds are formed between molecules for various functions. The interaction between atoms of the same molecule termed as intermolecular bonds are also non-covalent interactions.
Non- covalent bonds are present in the helix formation.
The non covalent interactions are hydrogen bonds, Van Der Waals forces dipole -dipole bonds and hydrobhic interactions.
The bonds formed in C-H is non-polar and thus are not involved in hydrogen bond hence non covalent interaction.
Answer:
the volume is 18.45 L
Explanation:
The computation of the volume when the temperature is increased to 60.0 K is shown below:
Since the gas occupied 12.3 L at a temperature of 40.0 k
And, the volume when the new temperature is 60.0 k
So, the volume is
= 60.0 k × 12.3 L ÷ 40.0 k
= 18.45 L
hence, the volume is 18.45 L
We know, Given mass = Molar mass * Number of moles.
A.) <span>1.25 mol CaF</span>₂
Number of moles = 1.25
Molar mass = 78
So, Mass = 78 * 1.25 = 97.5 g
B.) 3.4 mol (NH₄)₂SO₄
Number of moles = 3.4
Molar mass = 132
Mass = 3.4 * 132 = 448.8 g
Hope this helps!
Answer:
d
Explanation:
Aluminium and Indian are in the same group/family
Sodium and Sulfer are in the same period
Elements of the same family have similar properties
Since sulfur and sodium aren't in the same family they dont share properties
The first option is correct. have fun in earth science i love astronomy!! :)
