Enzymes are needed for metabolic pathways in the body, respiration, digestion and other important life processes. When enzymes function properly, homeostasis is maintained. However, if an enzyme is lacking or has an incorrect shape due to genetic mutation, this can lead to disease within an organism.

A strip of zinc metal was placed in a beaker that contained 120 mL of a solution of copper (II) nitrate, Cu(NO3)2(aq). The mass

jeka94

Answer:

molarity 0.1

Explanation:

mass of copper nitrate =2.4

no of moles exist in 120ml= 2.4/187.5=0.0128mole

molarity =.0.0128/.12=0.1m

Volume of CO₂ obtained : 13 L

<h3>Further explanation</h3>

Reaction

C₂H₅OH + 3 O₂ ⇒ 2 CO₂ + 3 H₂0 + 8842 Joules

moles of ethanol=0.28

From equation, mol ratio ethanol : CO₂ = 1 : 2, so mol CO₂ :

$\tt \dfrac{2}{1}\times 0.28=0.56$

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

Then volume of CO₂ :

$\tt V~CO_2=mol\times 22.4=0.56\times 22.4=12.544\approx 13~L$
