What has to happen in order for a spontaneuos combustion to occur?
Spontaneous combustion occurs by self heating, thermal runway and then ignition. Woodlands, shrubs and grasslands are sometimes victims of spontaneous combustion during extremely dry weather.
What are two chemical reactions that require energy in order to occur?
This type of reaction is called ENDOTHERMIC REACTION.
A chemical equation must be balanced in order to show that mass is conserved during a reaction?
Yes. This is due to the law of conservation of mass/matter.
What are pseudo-first order reactions and do they differ from first order reactions?
For the IUPAC definitions see the link below.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).

What quantities are conserved when balancing a nuclear reaction?
In order for a nuclear reaction to be balanced, there are quantities that must be conserved. The quantities are the atomic numbers and mass numbers of the particles involved in the reaction.
What are pseudo-first order reactions and do they differ from first order reactions?
For the IUPAC definitions see the link below.
During the stage of internal combustion engine operation in which the piston rises and compresses the fuel in the combustion chamber?
This is called the compression stage. During the four stroke sycle (Otto cycle) the four stokes are induction, compression, power and exhaust. Each piston does this in a set order to even out the stresses caused, and thereby smooth the output. For example the firing order (i.e. power stroke) on a four cylinder engine could be 1,3,4 and 2 or 1,2,4 and 3.
Why a reaction needs to take place at equilibrium?
Many chemical reactions, like combustion , go to completion and not to equilibrium. It is normally desirable to give a chemical reaction time to reach equilibrium in order you get the maximum yield of one or more products.
What is a combustion analyzer used for?
A combustion analyser is used for combustion analysis, which is used in biology and chemistry. It is used to analyse the components of an item in order to find the composition of materials.
What is anaerobic combustion?
Anaerobic reactions are such reactions that do not require air in order to occur. Anaerobic combustion would be something burning without ambient oxygen. Traditional examples are sealed septic systems where bacteria digests biowaste products and, also, wet hay spontaneously combusts, even fermenting wine releases heat anaerobically. Anaerobic combustion was developed by Nazi Germany during World War Two to propel U-Boat submarines with limited success. Applications of anaerobic combustion before and after that event are obscure. Competing solutions to oxygenize fuel for more complete combustion of fossil fuels are prolific. Nitrous Oxide is one chemical to increase performance of sports cars by diluting the 70% Nitrogen component of ambient air without the use of turbochargers or superchargers to increase manifold pressure. "Anaerobic combustion" as a term is slightly deceiving in that it is used to describe a combustion process, typically 4-cycle engines, that are not aspirated by Earth's atmosphere to accomplish combustion. Mostly, all combustion processes rely on the presence of oxygen with fuel exposed to an ignition device to perform combustion inside Internal Combustion Engines (ICE). Improving technology has made possible ICEs that have a closed loop fuel system sealed away from its environment. Oxygen and fuel(s) are regenerated from combustion products (exhaust gases) and re-entered into the intake manifold. Presently, regeneration requires a large tank to hold hot expanded combustion gases and engine output is decreased. Oxygen infused fossil fuels are a consideration to improve anaerobic combustion but presently, market forces eschew the added expense and hazard of higher volatility.
What change that needs heat in order to take place?
combustion
Is there a picture of the firing order for a 1995 Camry 4 cylinder engine?
There is a picture of the firing order of a 1995 Toyota Camry 4 cylinder engine in the vehicle's service manual. The firing order determines when each cylinder is ignited during the combustion cycle.
