Answer:
<em>The flow of thermal energy in a system, at constant atmospheric pressure AND at thermodynamic standard temperature and pressure.</em>
<h3>The temperature is 15.58 kelvin </h3>
<em><u>Solution:</u></em>
<em><u>Ideal gas equation is given as:</u></em>

Where,
P = pressure
V = volume
n = amount of substance
R = ideal gas constant
T = temperature
From given,
V = 120 liters
n = 5 moles

P = 5.4 kPa
T = ?
Therefore,

Thus the temperature is 15.58 kelvin
Copper nitrate
Copper nitrate is the oxidizing agent as it gets reduced from +2 to 0 oxidization State and oxidize Fe from 0 to +2 state.
Living things are highly organized and structured, following a hierarchy of scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms combine to form molecules, which are chemical structures consisting of at least two atoms held together by a chemical bond. In plants, animals, and many other types of organisms, molecules come together in specific ways to create structures called organelles. Organelles are small structures that exist within cells and perform specialized functions. As discussed in more detail below, all living things are made of one or more cells.
