To measure the density of the stone placed in a graduated cylinder let us follow these steps bellow

  1. Measure the volume of water poured into a graduated cylinder
  2. Place the object in the water and remeasure the volume.
  3. The difference between the two volume measurements is the volume of the object.
  4. Divide the mass by the volume to calculate the density of the object.

<em>We know that the formula for density is given as </em>

Given data

Mass = 8gram

Initial Volume of water in cylinder = 25mL

Final Volume of water in cylinder  = 29mL

Hence the volume of the rock  = 29-25 = 4mL

Therefore the density of the rock = 8/4 = 2 g/mL

What is the ratio of [a–]/[ha] at ph 3.75? the pka of formic acid (methanoic acid, h–cooh) is 3.75?
Vikentia [17]

The formula for pH given the pKa and the concentrations are:

pH = pKa + log [a–]/[ha]

<span>
Therefore calculating:</span>

3.75 = 3.75 + log [a–]/[ha]

log [a–]/[ha] = 0

[a–]/[ha] = 10^0

<span>[a–]/[ha] = 1</span>

Analyze the bonds of CCl4. What is the shape of the CCl4 molecule? Is it symmetrical? Does this mean that the CCl4 molecule is p
Crank

C-Cl bond is polar.


As Cl is more electronegative than C,  

Cl pulls the shared electrons towards its side making the C-Cl bond polar.


Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.


CCl4 molecule is tetrahedral.

And its shape is symmetrical.


That means its similar on all corners or all planes and it can be cut into equal halves from any plane.


C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.


Since the molecule is symmetrical CCl4 is non polar.
