A Flame test is an example of chemistry property. What evidence can you use to back your statement up?
Lena [83]
The flame test is a qualitative test used in chemistry to help determine the identity or possible identity of a metal or metalloid ion found in an ionic compound. If the compound is placed in the flame of a gas burner, there may be a characteristic color given off that is visible to the naked eye. And for the proof. The flame test provided evidence that specific atoms are present in compounds by the color of the flame. The metal atoms are what is responsible for the colors during the flame test. The color of the flame will be yellow-orange because Sodium (Na) is present in all the compounds that have a yellow-orange flame. Hope this helps! Mark brainly please!

during a bread making process glucose is converted to ethanol and carbon dioxide causing the bread dough to rise by itself this
yaroslaw [1]

Answer:

Zymase is acting as a catalyst

Explanation:

Zymase is an enzyme that is naturally produced in yeast. Enzymes are biological catalysts that speed up the rates of reactions in living things.

Zymase catalyses the breakdown of glucose into ethanol and carbon dioxide, which causes the bread to rise.

Zymase speeds up this reaction, but is not physically changed itself. Therefore, it is a catalyst.

Actually, zymase represents a collection of enzymes in yeast, not just one!
