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!
What is called compound?
- In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
- When the elements come together, they react with each other and form chemical bonds that are difficult to break.
- These bonds form as a result of sharing or exchanging electrons between atoms.
a) Mg(OH)2 or Ni(OH)2.
Mg(OH)2 1.8×10–11
Ni(OH)2 2.0×10–15
Clearly, Ksp value for Mg(OH)2 is higher , meaning it is MUCH MORE SOLBULE than Nickel
therefore, choose Mg(OH)2.
b)
PbS 3×10–28
CuS 6×10–37
Clearly, PbS is much more soluble than CuS
since Ksp is higher .
c)
Ag2SO4 1.4×10–5
MgF2 3.7×10–8
Clearly, Ag2SO4 has higher Ksp, so it is much more soluble.

706000 in scientific notation is 7.06x10^5
No the car is not accelerating because it is going at a constant speed.This is a trick question because human nature urges us to imagine the activity taking place. Our perception will be acceleration due to the inertial forces being applied in the original direction of travel as the car turns.In reality the car is moving at a constant speed, and the physical forces related to direction change are applied and absorbed at the same time.
