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:
true
Explanation:
Hotter things have more heat energy than colder things. That's because the atoms or molecules move around faster in hot things (red, right) than they do in cold things (blue, left). ... The more heat you supply, the faster the molecules move and the further apart they get.
Inhalation is the process of taking air into the lungs. For this to occur, the air pressure inside the lungs must be lower than that of the external atmosphere as air flows from areas of higher pressure to lower pressure. <span>Exhalation is the process of expelling air out of the lungs. For this to occur, the air pressure inside the lungs must be higher than that of the external atmosphere as air flows from areas of higher pressure to ones of lower pressure.</span>
Explanation:
the last CH2 should CH3
because the first and last carbons are bonded to three hydrogens
Answer:
9.6 t
Explanation:
You want to convert tablets ⟶ tons
I would use the conversion sequence:
tablets ⟶ milligrams ⟶ grams ⟶ kilograms ⟶ pounds ⟶ tons
===============
1 tablet = 500 mg Convert tablets to milligrams
Milligrams = 85 × 10⁶ × 500/1
Milligrams = 4.25 × 10¹⁰ mg
===============
1000 mg = 1 g Convert milligrams to grams
Grams = 4.25 × 10¹⁰ × 1/1000
Grams = 4.25 × 10⁷ g
===============
1000 g = 1 kg Convert grams to kilograms
Kilograms = 4.25 × 10⁷ ×1/1000
Kilograms = 4.25 × 10⁴ kg
===============
I kg = 2.205 lb Convert kilograms to pounds
Pounds = 4.25 × 10⁴ × 1/2.205
Pounds = 1.93 × 10⁴ lb
===============
1 t = 2000 lb Convert pounds to tons
Tons = 1.93 × 10⁴ × 1/2000
Tons = 9.6 t
