Enzymes are highly reaction-specific. An enzyme is a catalyst, meaning they greatly increase the rate of reaction. However, they only work in very specific reactions, which they are tailored for.
1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>
<em>2. Physical state of the reactants and surface area.</em>
Answer:
Mass = 3. 6 ( 2 significant digits)
Explanation:
Number of moles = 0.045
Mass = ?
Relationship between number of moles and mass is given as;
Number of moles = Mass / molar mass
Mass = Number of moles * Molar mass
Mass = 0.045 * 80.91g/mol
Mass = 3.641
Mass = 3. 6 ( 2 significant digits)
The Olivine normally crystalizes first from the magma of the mafic minerals, It crystalizes at between 1200°C and 1300°C. when the temperature of magma drops and there is a silica still remains in the magma so the olivine reacts with this silica to form pyroxene.and by more cooling of the temperature of magma and there is a silica still remains in magma pyroxene change to amphibole, and amphibole to biotite.when the pyroxene strat to form the plagioclase feldspar also forms.
