Explanation:

In the given version of an Einstein's equation:

\Delta m = \frac{E}{c^2}

\Delta m = Mass defect

E = Nuclear binding energy of an atom which holds the nucleus of an atom together.

c = speed of the light =3\times 10^8 m/s

From the given version one can determine the mass defect which is a binding force of a nucleus in an atom if nuclear binding energy is known.

<u>Answer</u>

mass


<u>Explanation</u>

E=mc² explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass.

It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.

E=mc²

m = E/c²

From the version in the question the value to be found directly is mass.

How many 250 mg tablets of metronidazole are needed to make 150 ml of suspension containing 100 mg/ml?
Viktor [21]
The  number  250 mg  tablets of Metronidazole  that  are needed to make  150  ml  of suspension containing 100 mg/ml

250mg= 150 ml

what  about 100 ml = ? Mg

by cross multiplication

150 ml x 250 mg/100 ml = 60 Mg   of  250 mg   is needed

To a 25.00 mL volumetric flask, a lab technician adds a 0.250 g sample of a weak monoprotic acid, HA , and dilutes to the mark w
Basile [38]

Answer: The number of moles of the weak acid in the solution is 0.00396

Explanation:

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}      

a) {\text{Moles of}KOH=0.0846M\times 0.04683L=0.00396mol

The balanced chemical reaction is:

HA+KOH\rightarrow KA+H_2O  

1 mole of base uses = 1 mole of HA  

0.00396  moles of base use = \frac{1}{1}\times 0.00396=0.00396 moles of HA  

Thus the number of moles of the weak acid in the solution is 0.00396

The rate of SN2 reaction of the type Nu- RX -&gt; R-Nu X- can be increased Select one: a. using a solvent of high polarity b. us
Gnoma [55]

Answer:

using higher concentration of the nucleophile

Explanation:

In SN2 reaction, the attack of the nucleophile on the substrate occurs simultaneously as the leaving group departs. The entering group normally attacks through the back side of the molecule. The reaction is concerted and bimolecular. This implies that the concentration of the nucleophile is important in the rate equation for the reaction. Hence increasing the concentration of the nucleophile will increase the rate of SN2 reaction.
