Answer:
Emulsion
Explanation:
Emulsion is a special type of mixture formed by combining two liquids that do not normally mix. An example of emulsion is;
Oil and Water

Answer:</h3>
1. Irreversible Inhibition-Inhibitor may permanently modify an enzyme
2. Irreversible inhibition- Tamiflu, a transition state analog, reversibly binds to neuraminindase
3. Competitive Inhibition-Inhibitor binds reversibly to an enzyme's active
4.Irreversible inhibition-Inhibitor binds to an enzyme at a site other than active site
5. Mixed inhibition-The Al3+ ion binds to acetylcholinesterase or to the acetylcholinesterase- substrate complex
6. Irreversible inhibition-DIPF permanently modifies the hydroxyl group of a Serine residue at the active site
<h3>
Explanation:</h3>
- An enzyme is a biological catalyst that catalysis chemical reactions.
- Enzyme activity is influenced by several factors which include enzyme inhibitors, temperature, and pH among others.
- Enzyme inhibitors are molecules that bind to the enzyme thus interfering with enzyme activity and preventing the binding of substrate to the enzyme.
- Inhibitors may either irreversibly or reversibly bind the enzymes.
- Competitive inhibitors compete with substrates for the active sites while non-competitive inhibitors bind irreversibly to other sites on the enzyme other than the active site.
- Tamiflu is an example of a competitive inhibitor.
- DIPF is an example of a non-competitive inhibitor as it binds the enzyme permanently.

Answer:
1.51 X 10^23 ions
Explanation:
The number of ions in 17.1 gm of aluminum sulphate Al2 (SO4)3 =….. [Molar mass of Al2 (SO4)3 = 342 gm]
in one molecule of Al2(SO4)3 there are 5 ions 2 aluminum and 3 sulfate ions
in 2 molecules there are 2X5= 10 ions
in 10 molecules there are 10X5 = 50 ions
molar mass of Al2(SO4)3 = (2 X 26.98) +( 3 X 32.1) + (3 X 4 X 16.0 ) =342.gms = 17.1/342 =0.0500 moles
1 mole =6.02 X 10^23 molecules ( see Avogadros number)
0.0500 moles = 0.0500 X 6.02 X 10^23 molecules =
0.301 X 10^23 molecules = 3.01 X 10^22 molecules
We determined that each molecule of Al2(SO4)3 has 5 ions
so 3.01 X10^22 molecules have 5 X 3.01 X 10^22 ions =
15.05 X 10^22 ions = 1.51 X 10^23 ions
