What else can I help you with?
If A log is burning in a fireplace. If the amount of oxygen reaching the log is decreased what happened to the reaction rate?
If the amount of oxygen reaching the burning log is decreased, the reaction rate of combustion will also decrease. Oxygen is a crucial reactant in the combustion process, and insufficient oxygen limits the ability of the log to sustain a vigorous fire. As a result, the flames may become smaller, and the log will burn less efficiently. Eventually, if oxygen levels are too low, the fire may extinguish.
What is the chemical energy in a log burning?
fire chemicals
How hot is burning log?
A burning log can reach temperatures up to about 600-900 degrees Celsius (1112-1652 degrees Fahrenheit), depending on the type of wood and conditions of the fire.
How does the law of conservation of mass apply to a burned log?
Even though you are burning the log, none of the mass is destroyed. The mass of the log and the oxygen involved in burning it will just be the sum total of all the by products; namely CO2, Carbon, and Water Vapor.
Example of energy transformation from chemical potential energy to thermal energy?
A log burning in a fire place.
Is a burning log a mixture?
A log is a mixture regardless of whether it is burning.
What is the name given to the chemical reaction that result in fire?
Fire(Burning) is a chemical change. Once you burn a log, you won't get the log back, that's how it's a chemical change. Also, Fire needs Oxygen (O2) to burn and stay alive but with too much Carbon Dioxide (CO2) it will die out.
Is burning logs a physical change?
No. Burning a log is a chemical change since the fire turns the wood into ash, water vapor, carbon dioxide, and elemental carbon.
Is burning a log a example of chemical or physical changes?
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
When was Burning Log - TV program - created?
Burning Log - TV program - was created in 1999.
Which is not a physical change hitting a log with an axe cutting a log burning a log or hammering a spike through a log?
Burning the log is a chemical change. All of the others are physical changes.
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Burning a log in the fireplace involves a chemical reaction because it undergoes combustion, reacting with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. Sawing a log in half is a physical change where the log is simply being cut into smaller pieces without any chemical reactions occurring.
