At this angle the biggest "area" of the test tube is covered by the flame. Thus it heats up quickly and evenly. Also, by holding the test tube at 45 degrees away from you, you're less likely to be splashed by anything in the test tube boiling over.

What is the notch angle in izod impact test.?
45 degree angle
What is FT2 on electrical cable?
FT2 on an electrical cord refers to the CSA (Canadian Standards Associations) test designation for wires and cables. FT2 is the minimum mandatory horizontal flame test for Flexible Cord. A burner flame is applied to a horizontal sample for five 15 second applications and must not exceed 100mm from end to end. There should also be no type of flame particles falling from the sample.
How do you know if a two triangles are congruent?
There are 4 tests that can be used, depending upon what you have:1) SSS (Side-Side-Side) - all three corresponding sides of the triangles are equal.2) AAS (Angle-Angle-Side) - two corresponding angles and one corresponding side are equal3) SAS (Side-Angle-Side) - two corresponding sides and the *ENCLOSED* angle are the same4) RHS (Right angle-Hypotenuse-Side) - The triangles are Right-angled with Hypotenuse and corresponding side equalIn test 2, if two angles are given then the third angle can be calculated, thus the order does not matter and ASA(Angle-Side-Angle) is equivalent and also proves congruency.Note the importance in test 3 that the angle is enclosed between the corresponding sides. If it is not enclosed, the triangles may be congruent, but they may also NOT be congruent. In this case the test you are using is Angle-Side-Side (ASS - which is what you would be to say that the triangles are congruent).Note that RHS is a special case of ASS (the only one which guarantees congruency) in that the angle MUST be a right angle (90°); this means that the third side of both triangles can be calculated using Pythagoras and RHS is effectively SSS.
What are the answers for the dogging certificate of competency test?
What is the factor that should be applied when using 2 leg sling directly attached with an included angle of 120 degrees
How does the angle of launch affect the range and trajectory of the projectile?
Easy . Think of it like this. The higher you angle your catapult (or whatever your using.) The higher it will travel but it will have less power. If you have a lower angle you will have more power but it your projectile will hit the ground first. If you don't understand just play around with a slingshot and an empty can of soda. Or you could test it out this theory by playing around with angry birds ;)
What is the notch angle in izod impact test.?
45 degree angle
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
What is the color of iron in aflame?
If you're referring to what chemists call a "flame test", then the characteristic color due to iron ions is yellow (which may not be terribly spectacular, depending on how hot the flame in question is). If you're referring to the color of an iron bar held in a flame, it depends on how hot the flame is; if it's held there long enough, it should be approximately the same color the flame itself is (assuming it doesn't melt first).
What color does Na-Cl burn in a flame test?
NaCl burns yellow in a flame test.
What is the flame test for aluminum?
Aluminium ions like Magnesium ions have no colour in a flame test
How do you know if something is copper for example a vase?
you need to do the flame test you need to do the flame test
How do you test for potassium ions?
Flame test
Does Copper Chloride produce a blue-green or Red flame?
In a flame test the copper ions in copper chloride will produce a 'blue/green' flame. To test for metal ions, the flame colour in a flame test is indicative of the metal present. Lithium = Red Sodium = Yellow Potassium = Lilac (pale purple). There are many more flame test colours.
Examples of constant variables in flame test?
The temperature of the flame.
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
What is the result with iron II chloride in the test flame?
Iron has a yellow-gold color in the flame test.
