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.
Answer:
C. This is because weathering is when a rock is broken down to smaller bits and destroyed. Hope this helps!
Answer:
B) 12
Explanation:
Given parameters:
Initial volume = 3L
Initial pressure = 4atm
Final pressure = 6atm
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
P₁V₁ = P₂V₂
P and V are pressure and temperature values
1 and 2 are initial and final states.
PV product = 3 x 4 = 12
Answer:
Mass = 2.64 g
Explanation:
Given data;
Mass of butane = 3.60 g
Mass of oxygen = 2.30 g
Mass of carbon dioxide produced = ?
Solution:
Chemical equation:
O₂ + C₄H₁₀ → CO₂ + H₂O
Number of moles of BUTANE:
Number of moles = mass/ molar mass
Number of moles = 3.60 g / 58.12 g/mol
Number of moles = 0.06 mol
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 2.30 g / 32 g/mol
Number of moles = 0.07 mol
Now we compare the moles ammonia with hydrogen and nitrogen
O₂ : CO₂
1 : 1
0.07 : 0.07 mol
C₄H₁₀ : CO₂
1 : 1
0.06 : 0.06 mol
The number of moles of carbondioxide produced by butane are less so it will limiting reactant.
Theoretical yield:
Mass = number of moles × molar mass
Mass =0.06 mol × 44 g/mol
Mass = 2.64 g
