Compound b has a molecular formula of c7h16o. what is the unsaturation number (un) or double-bond equivalent (dbe)?
aksik [14]

Answer: -

Zero

Explanation: -

Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.

The double bond equivalent for an organic compound can be found out by the help of the formula

DBE = C+1 -0.5 H - 0.5 X + 0.5 N

The chemical formula of the compound B = C₇H₁₆O

So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.

Plugging into the formula,

DBE = 7 + 1 - 0.5 x 16

      = 0

Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O

What mass of silver can be plated onto an object in 33. 5 minutes at 8. 70 a of current? ag (aq) e- → ag(s) 19. 6 g 9. 78 g 0. 3
grandymaker [24]

Mass of silver can be plated onto an object in 33. 5 minutes at 8. 70 a of current is 19.55 g

Given, I=8.70A, t=33.5min=33.5*60=2010 sec, m of Ag = 19600g M=107.87 g/mol

From  faradays law we can write q=I*t= 8.70*2010=17487 C.

moles of Ag =17487/ 19600=0.1812 moles

Ag deposited = 0.1812*107.87 = 19.55 g

<h3>Silver </h3>

Having the atomic number 47 and the Latin word argentum, which means "bright" or "white," silver is a chemical element. Its symbol is Ag. The highest electrical, thermal, and reflectivity of any metal are displayed by this transition metal, which is soft, white, and lustrous. The metal can be found in the Earth's crust in three different forms: as an alloy with other metals like gold and in minerals like argentite and chlorargyrite. It can also be found in its pure, free elemental form, also known as "native silver." During the refining of copper, gold, lead, and zinc, the majority of silver is created as a byproduct. As a valuable metal, silver has long been treasured.

What mass of silver can be plated onto an object in 33. 5 minutes at 8. 70 a of current? ag (aq) e- → ag(s) 19. 6 g 9. 78 g 0. 326 g 3. 07 g 0. 102 g
