Answer:

53.93 g Ag

Explanation:

3.011x1023 atoms  Ag x  <u>   1 mole  Ag     </u>   x   <u>107,8683  grams</u>  =

                                      6.022x10^{23} atoms           1 mole Ag

use the periodic table fo find Ag atomic mass and use Avogadro´s number

Consider the following equation in chemical equilibrium. C2H4(g) + H2(g) mc009-1.jpg C2H6(g) + 137 kJ What happens to the amount
Novosadov [1.4K]
The correct answer is a) the amount of ethane decrease.
because this reaction is an exothermic reaction and the heat is a product of this reaction, So when the number of temperature increases so (more heat will be added) so the reaction will go leftward (toward reactants ) so the amount of C2H4 & H2 will increase and the amount of ethane C2H6 will decrease.

In the step gradient separation, four separate fractions were collected. How were these related to the polarities of the column
max2010maxim [7]
<span>  These related to the polarities of the column and of the eluting solvent </span><span>When you run a column are 
 1) always start with a more non-polar solvent ratio and SLOWLY increase the polarity of the solvent.
1) Columns are generally made with silica which is highly polar, so compounds that are more polar in nature will interact with the silica more than those that are non-polar.
 3) The first fractions to come out should be most non-polar, with each fraction collected after that being more and more polar.
hope this helps</span>

As a star gives off energy in a thermonuclear reaction, the mass of the star
Law Incorporation [45]
Decreases. Mass and energy may be converted, but neither created nor destroyed. If you convert an amount of mass into energy, then that mass is lost as energy.
