If one atom or molecule is giving electrons, another must be taking (or sharing). That's why the common term is redox reactions. An oxidation reaction occurs when the chemical change of an atom or molecule is accompanied by a net loss of electrons. A reduction reaction is the opposite - a net gain of electrons. Since electrons, like atoms, are not created or destroyed in chemical reactions, an reduction reaction cannot occur without a source of electrons - which is the oxidation reaction. An oxidation reaction cannot occur without a reduction reaction because free electrons are highly reactive will attach themselves to the nearest atom/molecule, effecting reduction.
The cost of installing a central heating system depends on different factors, such as the size of the house, the complexity of the installation and the type of system installed. An average cost for either a heat pump or a gas furnace system in 2014 may be around $10,000 to $20,000, depending on the above factors. Continue Reading.
The average cost to install a new furnace is $3,602. As always, the price largely depends on the efficiency and size of your furnace, as well as its heat source. We have seen homeowners spend as little as $1,500 on a new furnace or as much as $7,000.However, know that most homeowners pay between $3,200 and $4,420.our furnaceâs warranty could decrease your furnace repair costs. A furnace that is still under warranty may have parts covered, but the homeowner may have to pay the cost of a service visit and for labor. When a furnace is no longer under warranty, the cost will depend on what the problem is.
