A sample of copper powder is heated in an evaporating dish using a Bunsen burner If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.
What factors affect the rate at which Bunsen burner heats water in a beaker?
tempareture ,nature of the substance and the controller of the bunsen burner
Can an evaporating dish be heated on a hot plate?
The evaporating dish would not be harmed if it was heated on a hot plate, but it should be heated on a bunsen burner.
When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
Which pieces of equipment would you use to evaporate a solution using a Bunsen burner?
evaporating dish and watch glass

How is a Bunsen burner used to identify a substance?
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.

What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
What is the function of the barrel of the Bunsen burner?
Control of the ratio gas fuel/air in the burner.
Which pieces of equipment would you use to evaporate a solution using a Bunsen burner?
evaporating dish and watch glass
Where does gas enter the Bunsen burner?
Gas enters the bottom of the Bunsen burner, where it travels up to mix with air before moving up the stem to meet the flame.
When a substance is placed over a Bunsen burner it does what?
It absorbes energy as heat.
