Answer:
Rate = 116m⁻¹s⁻¹[lactose][H]⁺
Explanation:
the formula for rate of reaction is given as
Rate = k[lactose]∧α[H]⁺∧β
we solve for the value of α and β
([lactose]₁/[lactose]₂)∧α
α = 
when we divide this equation
α = 
α = 1
we find β
R₁/R₂ = 0.01/0.02(0.001/0.001)∧β
0.00116/0.00232 = 0.5(1)∧β
β = 1
Rate = k[lactose]∧α[H]⁺∧β
we have to find the value for k
k = 0.00116/0.01(0.001)
k = 0.00116/0.00001
= 116m⁻¹s⁻¹
<u>Rate = 116m⁻¹s⁻¹[lactose][H]⁺</u>
The sugar that occurs in nucleotides tends to be a 5 carbon sugar called ribose or deoxyribose and tends to be represented by a pentagon of 5 carbons joined to oxygen and OH to form part of the helix forming nucleic acids. The nucleotides are what constitutes the DNA and RNA which control genetic characteristics.
32.) 55.6 mL HCl
33.) 0. 128 M
Answer:
Explanation:
Heat flow equation => q = m·c·ΔT
m = mass in grams = 10.00 grams
c = specific heat (a constant) = 0.900j/g·°C
ΔT = temperature change in °C = 50°C - 25°C = 25°C
q = (10.00g)(0.900j/g·°C)(25°C) = 225 joules absorbed*
*absorbed => endothermic process => need to show 'plus' energy change.
If the reactions were an exothermic process the problem would use terms like energy released, energy lost, energy given-up, etc... => would require using a 'negative' signage before the calculated energy value. So, the correct choice is the +225 joules value.
