Answer:

cycloocta-1,4-diene- isolated double bond

cycloocta-1,3-diene- conjugated double bond

cyclodeca-1,2-diene- cumulated double bond

cycloocta-1,3,5,7-tetraene- conjugated double bond

cyclohexa-1,3,5-triene (benzene) - conjugated double bond

penta-1,2,4-triene- cumulated and conjugated double bond

Explanation:

A conjugated double bond is a system that contains alternate double and single bonds. It is renowned for its unusual stability.

A cumulated double bond is a double bond system involving about three atoms e.g C=C=C.

An isolated double bond is a system of double bonds separated by more than one single bond.

16. A sample of nitrogen gas,
Lana71 [14]

find mol of N2 present using gas law equation

PV = nRT

P = pressure = 688/760 = 0.905 atm.

V = 100mL = 0.1L

n = ???

R = 0.082057

T = 565+273 = 838

Substitute:

0.905*0.1 = n*0.082057*838

n = 0.0905 / 68.76

n = 0.00132 mol N2

Molar mass N2 = 28 g/mol

0.00132 mol = 0.00132*28 = 0.037g N2 gas

Select all of the items that are true about a sample of water vapor at 101°C as it cools.
Dvinal [7]
<h3><u>Answer;</u></h3>

A) Its temperature will fall continuously until it condensed into a liquid.

<h3><u>Explanation</u>;</h3>
  • <em><u>Steam or water vapor is the gaseous state of liquid water.  When water vapor above a temperature of 100 degrees Celsius is cooled, the temperature falls continuously, and it undergoes condensation at a temperature of 100 degrees Celsius and turns into liquid water.</u></em>
  • The change of state from gaseous to liquid state occurs as a result of latent heat of vaporization that the water vapor carries.

After undergoing alpha decay, an atom of radium-226 becomes
Zanzabum
The answer is b. radon-222. The alpha decay means that it will emit an alpha particle when decays. The alpha particle has two protons and two neutrons. So Radium(88) minus two protons will become Radon(86). And the atomic mass will become 226-4=222.
