The answer is C as enzymes are biological catalysts that act on a substrate such as starch if the enzyme were amylase
hope that helps
Combustion equation of n-hexane:
2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
a)
Assuming we have 100 moles of air,
Oxygen = 20.9 moles
n-hexane required = 20.9/19 x 2
= 2.2 moles
LFL = Half of stoichometric amount = 2.2 / 2 = 1.1
LFL n-hexane = 1.1%
b)
1.1 volume percent required for LFL
1.1% x 1
= 0.0011 m³ of n-hexane required
Answer:
5 L
Explanation:
Use Charles law and rearrange formula
Change C to K

Answer:
Explanation:
Boyle believed that chemistry – the behavior of substances – could be explained through the motion of atoms, which in turn could be understood through mechanics – Galileo's mathematics of motion. Boyle was ultimately proved correct, because today we can understand chemistry mathematically, through quantum mechanics.
Answer:
In a volumetric flask of marking 500.0 mL add 138.75 grams of calcium chloride and add small amount of water to dissolve solute completely. After the solute gets completely soluble add more water up till the mark of 500 ml.
Explanation:
Concentration of calcium chloride = 2.5 M
Volume of the solution = 500.0 ml = 0.5000 L
Moles of calcium chloride = n
n = moles of solute
c = concentration of solution
V = volume of the solution in L
Mass of calcium chloride = 111 g/mol × 1.2500 mol = 138.75 g
In a volumetric flask of marking 500.0 mL add 138.75 grams of calcium chloride and add small amount of water to dissolve solute completely. After the the solute gets completely soluble add more water up till the mark of 500 ml.
