Partial charges occur when ... partial charges occur when ... (a) a covalent bond links atoms of two kinds. (b) atoms share elec

Gnoma [55]

<span>Answer: option (b) atoms share electrons unequally.

That is because although the molecule or compound is neutral, some atoms will bear more electron density than others, so the atomes inside the compound that have more electron density will be partially negative while the atoms with less electron density will be partially positive.

Consider the following generic chemical equation: A + B → C + D Reactant A contains 85.1 J of chemical energy. Reactant B contai

irakobra [83]

Answer:

Product D contains 30 J

Explanation:

We know energy does not destroy or create, it only transforms. So, at the right side of the equation we have the energy of the reactant A and the energy of the reactant B, as a sum, and, as a result we have to get the same energy plus the energy absorbed by the reaction.

So, we have,

Ea+Eb = Eabsorbed+Ec+Ed

Ed = Ea+Eb-Eabsorbed-Ec

Ed = 85.1 J + 87.9 J - 104.3 J - 38.7 J

Ed = 30 J

Azobisisobutyronitrile (AIBN) is commonly used as a radical initiator. Use correct arrow formalism to show this process.

Dahasolnce [82]

Answer: AIBN is good radical initiator

Explanation:

A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.

what is the amount of heat,in joules, required to increase the temperature of a 49.5-gram sample of wanted from 22c to 66c

aniked [119]

Answer :

the amount of heat,in joules, required to increase the temperature of a 49.5-gram sample of wanted from 22°c to 66°c is 9.104 Joules.

Explanation:

The answer can be calculated using the formula

Q = mCрΔT

where

Q is the amount of heat required in joules to raise the temperature.

m is the mass of the sample in Kg.

Cp is the specific heat of the sample in J/Kg°C.

ΔT is the change in temperature required.

Here, m = 49.5-gram = 0.0495 kg

Cp = 4.18 J/Kg°C (for water)

T₁ = 22°C ; T₂ = 66°C

ΔT = 66 - 22 = 44

Substituting values in Q = mCрΔT

Q = (0.0495)(4.18)(44)

Q = 9.104 J
