Que relación tiene el metabolismo celular con el mantenimiento de los seres vivos

Chemistry

Dmitry [639]3 years ago
5 0
El metabolismo es un proceso por el cual los seres vivos ganan masa y energía que ofrece el medio en el que viven y sirve para el mantenimiento, crecimiento y reproducción de estos.

Si tomamos en cuenta la clasificación de los seres vivos tenemos:

- Autótrofos: Crean su propio alimento por medio del sol o la tierra y no de otros seres vivos (plantas, vegetales y algas).

- Heterótrofos: Generan su propio alimento y dependen de los autótrofos o de otros heterótrofos para su alimentación (animales y algunas bacterias).

El metabolismo se divide en dos procesos conjugados, el catabolismo y el anabolismo. Estos procesos dependen el uno del otro.

Las reacciones catabólicas liberan energía, mientras que las reacciones anabólicas, utilizan esa energía liberada para recomponer enlaces químicos y construir componentes de las células como las proteínas y los ácidos nucleicos..

De esta manera se relacionan ambos

How many moles of NH3 can be produced from 12.0 mol of H2 and excess N2? Express your answer numerically in moles. View Availabl
VladimirAG [237]

Answer:

A) 8.00 mol NH₃

B) 137 g NH₃

C) 2.30 g H₂

D) 1.53 x 10²⁰ molecules NH₃

Explanation:

Let us consider the balanced equation:

N₂(g) + 3 H₂(g) ⇄ 2 NH₃(g)

Part A

3 moles of H₂ form 2 moles of NH₃. So, for 12.0 moles of H₂:

12.0molH_{2}.\frac{2molNH_{3}}{3molH_{2}} =8.00molNH_{3}

Part B:

1 mole of N₂ forms 2 moles of NH₃. And each mole of NH₃ has a mass of 17.0 g (molar mass). So, for 4.04 moles of N₂:

4.04molN_{2}.\frac{2molNH_{3}}{1molN_{2}} .\frac{17.0gNH_{3}}{1molNH_{3}} =137gNH_{3}

Part C:

According to the <em>balanced equation</em> 6.00 g of H₂ form 34.0 g of NH₃. So, for 13.02g of NH₃:

13.02gNH_{3}.\frac{6.00gH_{2}}{34.0gNH_{3}} =2.30gH_{2}

Part D:

6.00 g of H₂ form 2 moles of NH₃. An each mole of NH₃ has 6.02 x 10²³ molecules of NH₃ (Avogadro number). So, for 7.62×10⁻⁴ g of H₂:

7.62 \times 10^{-4} gH_{2}.\frac{2molNH_{3}}{6.00gH_{2}} .\frac{6.02\times 10^{23}moleculesNH_{3}  }{1molNH_{3}}=1.53\times10^{20}moleculesNH_{3}

Find the volume of a gas if 3.6 mols of the gas is at STP
Digiron [165]

Answer:

81 L gas

General Formulas and Concepts:

<u>Ideal Gas Law</u>

  • STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

<u>Stoichiometry</u>

  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

[Given] 3.6 mols gas at STP

[Solve] volume (L) of gas

<u>Step 2: Convert</u>

  1. [DA] Set up:                                                                                                       \displaystyle 3.6 \ mol \ gas(\frac{22.4 \ L \ gas}{1 \ mol \ gas \ at \ STP})
  2. [DA] Multiply [Cancel out units]:                                                                      \displaystyle 80.64 \ L \ gas

<u>Step 3: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

80.64 L gas ≈ 81 L gas
