<span>To solve this question we have the density of gold expressed in gram per milliliter and we want to express in decigrams per liter. First we are going to change gram to decigram, knowing that 1 gram are 10 decigrams: 19,3 g/ml * 10 dg/1 g = 193 dg/ml Then we change milliliter to liter, knowing that 1000 ml are 1 liter: 193 dg/ml * 1000 ml/1 l = 193000 dg/l So then, density of gold is 193000 decigram/liter</span>

The whole cloves are broken up to help release the eugenol during distillation.
GREYUIT [131]

The statement is False.

No, whole cloves are not broken up to help release the eugenol during distillation.

Steam distillation:

  • Live steam is used in the co-distillation technique of steam distillation to separate mixture components.
  • It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity.
  • It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts.
  • The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water.
  • A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.

Write the lewis structure for mgi2. draw the lewis dot structure for mgi2. include all lone pairs of electrons.
viktelen [127]
Lewis Structure is drawn in following steps,

1) Calculate Number of Valence Electrons:
    
# of Valence electrons in Mg  =  2
# of Valence electrons in I      =  7
# of Valence electrons in I      =  7
                                               ---------
Total Valence electrons          =  16

2) Draw Mg as a central atom surround it by two atoms of Iodine.

3) Connect each Iodine atom to Mg, and subtract two electrons per bond. In this case we will subtract 4 electrons from total valence electrons. i.e.

Total Valence electrons           16
- Four electrons                    -   4
                                              ----------
                                                  12

4) Now start adding the remaining 12 electrons on more electronegative atoms i.e. Iodine.

The final lewis structure formed is as follow,
