How many moles are found in a 100.0 g sample of CuF2?
2 answers:
<span>The molar mass is calculated by the sum of the mass numbers of the atoms that form the molecule. For example: CuF2
</span>Cu: 1*63,54u = 63,54u
F: 2*19u = 38u
Thus, the molar mass of CuF2 is: 63,54+38= 101,54 g/ mol.
<span>And the number of mol is calculated by the mass divided by the molar mass or it can be solving through the rule of 3. For example:
</span>100 g de CuF2
101,54 g → 1 mol
100 g → x
101,54x = 100
x = 100/101,54
x = 0,98483... →

Answer: C. High surface tension
Explanation:
Water has high specific heat as it require high heat to raise the temperature of 1 g of water through .
Surface tension is the net downward force acting on the surface of liquids due to the cohesive nature of liquids.
Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom making it polar. Thus water molecules present on the surface are strongly attracted by the molecules present below the surface and thus act as a stretched membrane.
The surface acquires a minimum surface are and thus acquire a spherical shape.
It's difficult to write it down, but I'll attach you a good example of hydroboration of indene. I hope you'll find it helpful.
