arbon disulfide
Chemistry
1 answer:
Ugo [173]3 years ago
5 0

Answer:

5.9 × 10² kJ

Explanation:

When carbon disulfide, CS₂, forms from its elements, heat is absorbed. The corresponding value for the standard enthalpy of formation of carbon disulfide is 117.36 kJ/mol. The thermochemical equation that represents this process is:

C(graphite) + 2 S(s, rhombic) ⇒ CS₂(g)   ΔH°f = 117.36 kJ/mol

117.36 kJ of heat are absorbed when 1 mole of CS₂ is formed. The amount of heat absorbed when 5.0 moles of CS₂ are formed is:

5.0 mol × 117.36 kJ/mol = 5.9 × 10² kJ

The amount of energy needed to split the nucleus into individual protons and neutrons​
Mila [183]

Answer:

The correct answer is nuclear binding energy.

Explanation:

The least amount of energy, which is needed to distinguish an electron from an atom or to break the neutrons and protons from the nucleus of the atom is termed as the binding energy. This form of energy is also called separation energy. When a bound system is produced, the binding energy is equivalent to the mass defect less the concentration of the mass or energy discharged.  

There are many types of the binding energy of which the energy, which is needed to dissociate a nucleus into the individual neutrons and protons is known as the nuclear binding energy.

Why does molecular polarity occur? ​
Jet001 [13]

Answer:

Water is polar because it has two unshared pairs of electrons on the central oxygen molecule. This causes the single covalent bonds between the central oxygen and both hydrogen to be pushed away. The hydrogen side of the water molecules has a positive charge and the oxygen side of the molecules has a negative charge.

A system is in equilibrium when the rate of the forward reaction is _____ the rate of the reverse reaction.
NemiM [27]

Answer:

Option 4) equal to

Explanation

When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant

The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by

For example, for the following reaction :

aA + bB ⇔ cC + dD

Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
