Why the platinum wire is repeatedly flame sterilized in the preparation of bacterial smears?
The platinum wire is flame sterilized to eliminate any potential contamination before collecting bacterial samples. This is crucial to prevent introducing new microbes into the specimen, ensuring that the collected bacteria are representative of the original sample. Additionally, flame sterilization helps prevent cross-contamination between different samples being tested.
Why must the paper touch the flame?
The paper must touch the flame to ignite and undergo combustion, which is a chemical reaction between the paper's cellulose fibers and the oxygen in the air. This process releases heat and light, resulting in the visible flame. Without direct contact with the flame, the paper would not reach the necessary temperature to ignite. Additionally, the flame serves as the initial source of energy that facilitates the combustion process.
What is temp of a netural flame?
The temperature of a neutral flame typically ranges between 1,300 to 1,600 degrees Celsius (2,372 to 2,912 degrees Fahrenheit). This type of flame is achieved by adjusting the fuel-to-air ratio to ensure complete combustion, resulting in a clean and efficient burn.
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
What is the evidence that indicates that only physical changes occur when a platinum wire is heated in a Bunsen burner flame?
The evidence that indicates only physical changes occur when a platinum wire is heated in a Bunsen burner flame includes the fact that the platinum wire does not combine with oxygen or any other element in the flame to form a new substance, and the wire retains its chemical properties after cooling down. The color change of the wire due to heating is a reversible physical change, and the wire can be restored to its original state without any alteration in its composition.
On a Bunsen burner which flame is the 'clean' flame for heating?
The clean flame for heating on a Bunsen burner is the blue flame. This flame has a well-defined inner cone and burns with complete combustion, producing a high temperature suitable for heating applications in the laboratory.
What color is ethylene flame?
clean blue flame
What uses a platinum wire dipped into a solution of the mineral?
A platinum wire dipped into a solution of a mineral can be used in various analytical techniques such as flame tests or voltammetry to detect and quantify the presence of specific elements or ions in the solution. The platinum wire acts as an electrode to facilitate the chemical reaction between the mineral solution and the analytical technique being used.
What are the release dates for Platinum Hit - 2011 Kiss the Flame 1-8?

How do you clean a FLAME SENSOR?
Clean it using steel wool.
How do you beat the Snowpoint gym in platinum version?
you need a fire type that know flame wheel or flame thrower
Why is a blue flame called a clean flame?
A blue flame is called a clean flame because it indicates complete combustion of the fuel, resulting in minimal production of soot and pollutants. The blue color is due to the high temperature of the flame, which signifies efficient burning without excess unburned fuel. This makes a blue flame more environmentally friendly compared to a yellow or orange flame.
What color is ethylene?
clean blue flame
