What is the correct order of processes in the accretion of planetesimals?

Chemistry
1 answer:
icang [17]3 years ago
4 0

Answer:

A). Collapse, condensation, accretion, clearing.

Explanation:

Planetesimals are described as the small solid astronomical objects which are the building blocks for the formation of solid planets. Accretion is described as the process in which the solid astronomical objects cluster to form larger objects that eventually leads to the formation of planets.

As per the question, the correct order of processes that are followed in this accretion process would be a collapse, condensation, accretion, clearing. First occurs the collapse of a nebula followed by condensation of cosmic dust grains. <u>After this, the accession or accumulation of solid parts takes place to form larger objects and this is immediately followed by the clearing of debris and dust to allow planets to form</u>. Thus, <u>option A</u> is the correct answer.

What happens when heat is removed from water?
mamaluj [8]

Answer: Option (d) is the correct answer.

Explanation:

When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.

Therefore, kinetic energy of the water particles decreases.

Se hacen reaccionar 100 g del agente oxidante con 25 g del agente reductor, según la reacción REDOX LaTeX: N_2\left(g\right)+H_2
Vesna [10]

Answer:

El reactivo en exceso es hidrógeno

97.12g NH₃ son formados

Explanation:

Basados en la reacción:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

El hidrógeno pasa de estado de oxidación 0 a estado de oxidación +1. Al perder un electrón se oxida y es <em>el agente reductor.</em>

El nitrógeno pasa de estado 0 estado -3. Al ganar 3 electrones se reduce y es el <em>agente oxidante.</em>

100g de N₂ son (Peso molecular: 28g/mol):

100g × (1mol / 28g) = 3.57 moles de N₂

Y 25g de H₂ son (Peso molecular: 2g/mol):

25g × (1mol / 2g) = 12.5 moles de H₂

Como 3 moles de hidrógeno reaccionan por mol de nitrógeno, las moles de nitrógeno que se necesitan para hacer reaccionar completamente 12.5 moles de hidrógeno son:

12.5 moles H₂× (1 mol N₂ / 3 moles H₂) = 4.17 moles de nitrógeno.

Como hay 3.57 moles de nitrógeno, <em>el reactivo en exceso es hidrógeno.</em>

<em></em>

Como el reactivo limitante es el nitrógeno y 1 mol de nitrógeno produce 2 moles de amoniaco, las moles de amoniaco son:

3.57 moles de N₂ × (2 moles NH₃ / 1 mol N₂) = <em>7.14 moles de NH₃</em>

La masa producida idealmente es:

7.14 mol NH₃ ₓ (17g/mol) = <em>121.4 g de NH₃. </em>Como la eficiencia del proceso es del 80%:

121.4 g NH₃ × 80% =<em> 97.12g NH₃ son formados</em>
