True or False, if false correct the statement:
A 10X solution (500mM Tris pH 8.0, 100mM ATP,) contains 1mM ATP at it's normal working concentration of 1X.
The given statement is FALSE.
As 10X concentration of solution contains 100mM ATP.
Now the concentration is reduced to 1X i.e., by a factor 1/10. Therefore the amount of ATP wii also reduced by a factor 1/10.
So, the solution will contain 10mM ATP at it's normal working concentration of 1X.

The composition of a 10X restriction enzyme buffer us: 500mM Potassium Acetate; 200 mM Tris-acetate; 100mM Mg Acetate; 1 mg/ml BSA. a) If you set up a reaction with 25 uL final volume, what volume of 10X buffer would you add to obtain 1X? b) In reference to the above, what is the final concentration of BSA in the 25 uL reaction?
Answer by true or false - if
false correct the statement.
( 7-) The mixture of equi 0.2M solution of sodium acetate and acetic acid has lower buffer capacity than the mixture of equi 0.5M NaCl and HCI. 8- Electron pair donor) is the definition of Lewis acid. false= acceptor if acid donor if base (9-) Ka of NH4OH is 5.376x10-10. (10- pH for 0.1 M Acetic acid ( Ka = 1.8 x10 -S) is 1.73.
Question II- Answer by False or True , if a statement is False , please correct it. 1- H2PO4 is a conjugate base of HPO42 and also amphoteric. 2- Benzoic acid( Ka = 6.5 x105) can be used to prepare efficient buffer of pH =6. 3- If excess NaOH dissolves Al(OH)only in a Mixture of Fe(OH)3/ Al(OH)3 this means that Fe(OH)3 is amphoteric substance. 4- Addition of NH4 CI(CI,NH4+) to a solution of NH4OH (NH4+, OH) will enhances its ionization....
True or False? If a solution having a pH = 7 is diluted 10 times by adding water, the new pH is 8. (correct answer: F) NH3 is a Lewis base. (correct answer: T) Al3+ is a Lewis acid.

Modified TRUE-FALSE. Write true if the statement is correct and if incorrect, change the underlined word to make the statement correct. IR spectra show absorption bands that enable to determine if certain functional groups are present in a molecule. IR spectra are expressed in wave number. Transmitted light have greater absorbance. (Emission) Absorption spectrum is the light of specific wavelength that is emitted when the atoms relax. When atoms absorb light of specific wavelength that causes the electrons to go...
