Why is it fairly safe to use a bunsen Burner to heat a solution that gives off hydrogen gas?
Bunsen burner is not used to obtain hydrogen.
Which cone gives off more heat on a Bunsen Burner?
A blue cone on a Bunsen burner gives off more heat because it has a higher temperature than a yellow cone. The blue cone represents complete combustion of the gas, while the yellow cone indicates incomplete combustion with lower temperature.
What was the feature that allowed the Bunsen burner to get a hot flame?
Robert Bunsen added an air hole to it so it could have oxygen as well as gas. when the air hole is open the flame you get is blue and is hotter than when the air hole is closed, which then gives a yellow flame.
What acid burns green in a Bunsen burner?
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color. Boron gives off a green color.
Which elements may be excited when NaBAKSrCa and Li are heated using Bunsen burner flame?
When NaBAKSrCa (sodium, barium, potassium, strontium, and calcium) and lithium are heated with a Bunsen burner flame, the elements that can be excited are primarily the alkali and alkaline earth metals. These elements absorb energy from the flame, promoting electrons to higher energy levels, which can then release light in characteristic colors when they return to their ground state. For instance, sodium produces a bright yellow flame, lithium emits a red flame, and barium gives off a green flame. The distinct colors can help identify these elements through flame tests.

What is the name of the flame when the air hole of a Bunsen burner is open?
Air hole fully open gives a 'roaring blue flame'
Why does closing the air hole on a Bunsen burner create an orange flame?
Because it starves it of oxygen, without oxygen the combustion is not as efficient. When the sides of the bunsen burner are open it draws air into the tube like a venturi and makes the combustion of the gas more efficient.i hope that my answer has helped you :)
Which type of Bunsen burner flame could you use for heating and why?
To heat substances effectively, you should use a blue flame produced by a well-adjusted Bunsen burner. This flame indicates complete combustion of the gas, resulting in a hotter and more efficient flame due to a higher oxygen-to-gas ratio. In contrast, a yellow flame is cooler and gives off soot, making it less suitable for heating purposes.
Which setting gives the hottest flame when using a Bunsen burner?
The blue flame is the hottest... The yellow one is called a safety flame and if you swipe your hand qckly through the safety flame, it won't burn... If you do it quick enough
Does a basic solution contain more hydroxide ions than hydrogen?
Yes, in a basic solution, there are more hydroxide (OH-) ions than hydrogen (H+) ions. This is what gives a basic solution its higher pH value compared to an acidic solution.
When acids in water what positive ion is produced in excess?
When acids in water hydrogen positive ion is produced in excess. It is this hydrogen positive ion that gives acidity of a solution.
Do acids release hydrogen ions?
yes they do and bases release hydroxide ions

Why does the roaring flame from the Bunsen burner turn red after passing through the wire gauze?
burner usually gives off blue flame because it receives enough oxygen to keep it burning at full strength. but after passing through wire gauze the flame turns red because it then receives a disrupted, less and unsteady amount of oxygen. this also causes the temperature of the flame to fall.
