Because sucrase will react with product and lower his concentration, so measurement of product concentration will not be accurate.
Sucrase activity is greater when sucrose concentration went from 2.5 to 7.5 g/l, because difference (increase<span>) between two concentration (numbers) is greater.</span>
Is this prier to a lab you've done?
Helium gas: He
Hydrogen gas: H₂
Oxygen gas: O₂
Explanation:
Gases can exist at room temperature in monoatomic form or sometimes as polyatomic molecules.
A wide range of elements exists as gases at room temperature. Most of their molecules have covalent bonds between their atoms which ensures that they are stable.
Other examples are:
- Argon gas Ar
- Neon gas Ne
- Bromine gas Br₂
- Nitrogen gas N₂
