Answer:
Hydrophobic amino acids
Explanation:
Hydrophobic amino acids are the amino acids which do not reside in the aqueous environment. These amino acids are generally buried within hydrophobic core of protein or the protein fold or lie in lipid portion of membrane.
Hydrophobic, as the term implies - hydro means water and phobic means fearing. These amino acids have little or almost no polarity in side chains. This lack of polarity make them water fearing.
Answer:
the melting point of aluminum is 660 degrees Celsius.
Answer:
Explanation:
We must do the conversions:
mass of CaCO₃ ⟶ moles of CaCO₃ ⟶ moles of CaCl₂
We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.
Mᵣ: 100.09 110.98
CaCO₃ + 2HCl ⟶ CaCl₂ + CO₂ + 2HCl
m/g: 27.9
(a) Moles of CaCO₃
(b) Moles of CaCl₂
