Answer:

reduced; oxidized

Explanation:

An electron transport chain can be defined as a series of redox reactions (electron transporters or proton complexes) that are saddled with the responsibility of transferring electrons from electron donors to electron acceptors through a membrane in order to produce a protein gradient that creates energy or adenosine triphosphate (ATP).

Generally, as these electrons are transferred through the electron transport chain, the molecules are first reduced as they pick up electrons, and then oxidized as they release the electrons.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

How many liters of O₂ are needed to react completely with 10.0 L of H₂S at STP
sergiy2304 [10]

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 10L of  H₂S should react with 6.6L of oxygen at stanadard pressure and temperature.

<h3>What is ideal gas equation?</h3>

Ideal gas equation is the mathematical expression that relates pressure volume and temperature.

Mathematically the relation between Pressure, volume and temperature can be given as

P×V=n×R×T

where,

P = pressure of gas

V= volume of gas

n =number of moles of gas

T =temperature of gas

R = Gas constant = 0.0821 L.atm/K.mol

At Standard temperature and pressure, 2 moles of  H₂S react with 3 moles of 0₂. S0, 10L of H₂S should react with 0.66×10=6.6L of oxygen.

Therefore, 10L of H₂S should react with 6.6L of oxygen.

How many moles of MgCl2 will be produced from 65.0g of Mg(OH)2 , assuming HCl is available in excess
Butoxors [25]

Answer:

1.12 moles of MgCl₂

Explanation:

Given parameters:

Mass of Mg(OH)₂  = 65g

Unknown:

Number of moles of MgCl₂ = ?

Solution:

To solve this problem, obtain a balanced reaction equation first;

           Mg(OH)₂  +   2HCl    →    MgCl₂   +   2H₂O

From the reaction above, this is a typical neutralization process in which an acid reacts with a base to produce salt and water only.

Let's proceed; the reactant in excess is the HCl, acid. The other reactant is the  Mg(OH)₂ and it must be the limiting reactant. A limiting reactant is one that is given in short supply and determines the extent of the reaction.

Find the number of moles of Mg(OH)₂;

   Number of moles  = \frac{mass}{molar mass} \\

     Molar mass of  Mg(OH)₂ = 24 + 2(16 + 1)  = 58g/mol

  Number of moles  = \frac{65}{58}    = 1.12moles

The balanced reaction equation shows that;

               1 mole of  Mg(OH)₂ gives 1 mole of MgCl₂

            1.12 mole of Mg(OH)₂ will produce 1.12 moles of MgCl₂
