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
<span>These elements are red. They are typically gaseous at normal temperatures: some examples can include oxygen, hydrogen, and the noble gases (neon, argon, krypton). These elements all use the concept of STP (standard temperature and pressure) as their baseline: 1 atmosphere of pressure and 0 degrees Celsius.</span>
Answer:
<u>The direction of dipole moment is C→Cl and electronegativity difference = 0.5</u>
Explanation:
The dipole moment is formed when there is a separation of charges in a chemical bond. The electrons of the bond tend to be more localized near the more electronegative atom.
The electronegativity of chlorine atom = 3.0 and electronegativity of carbon atom = 2.5
Therefore, chlorine is more electronegative than carbon. So, the electrons tend to be localized more near the electronegative chlorine atom. <u>Therefore, the direction of dipole moment is C→Cl and electronegativity difference is equal to 0.5.</u>
Answer:1.26 x 1010
Explanation: There really isn't anything to explain.
Well they can be used to make electromagnets that can power a lot of things like door bells and if you have a large not like the size of a fist larger enough to power a house or a decent sized building.
So we know that there are two types of electric currents AC and DC. (AC-DC). The flowing electrons produce something called a magnetic field and the spinning magnets cause Electric current to flow between copper wire.
Example time!
Take a battery, copper wire, and a magnet. Battery connection thing. So place the battery at the bottom put the magnet on top. With the copper wire put it into loops and when place above the battery and magnet. Give it a slight push and it should spin because of the reaction
