Answer:
In the absence of urease this will take 950 * 10^6 years to completely hydrolyze
Explanation:
The enzyme urease enhances the rate of urea hydrolysis at pH 8.0 and 20 degrees by a factor of 10^14 . If a given quantity of urease can completely hydrolyze a given quantity of urea in 5 min at 20 degrees and pH 8.0, how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease?
Step 1: data given
The enzyme urease enhaces the rate of urea hydrolysis at pH = 8.0 of centigrade by a factor of 10^14
Temperature = 20.0 °C
Step 2: Calculate the time it takes to completely hydrolyze without urease
This means when urease is available it takes 5 minutes to completely hydrolyze
When urease is not available it will take 5 *10^14 minutes
5 * 10^14 min = 5 * 10^14 minutes
Since 1 hour = 60 minutes
1 day = 24 hours = 24 *60 minutes = 1440 minutes
It would take : 5 * 10^14 minutes / 1440 minutes = 347222222222.2 days
Since 1 year = 365 days
This will take: 347222222222.2 / 365.25 = 950642634.4 years
This 950 * 10^6 years
In the absence of urease this will take 950 * 10^6 years
Answer:
The proton and electrons are equal,
15protons and 15electrons
Explanation:
An atom is the smallest electrical neutral particle of an element so it means that every atom have same number of protons and electrons.
Answer:
1(a) N = 3
(b) N = 0
(c) N = 5
(d) N = -2
(2) Molecular formula for benzene is C6H6
Explanation:
1(a) N02 1-
N + (2×-2) = -1
N-4 = -1
N = -1+4 = 3
(b) N2
2(N) = 0
N = 0/2 = 0
(c) NO2Cl
N + ( 2×-2) + (-1) = 0
N - 4 - 1 = 0
N - 5 = 0
N = 0+5 = 5
(d) N2H4
2(N) + (4×1) = 0
2N + 4 = 0
2N = 0 - 4 = -4
N = -4/2 = -2
(2) Molcular mass of benzene = 78g/mole = (6×12g of carbon) + (6×1g of hydrogen) = 72+6 = 78g/mole
Therefore, molecular formula for benzene is C6H6
