_
Kryger [21]

Answer:

<em>The correct option is b. new species make the environment less suitable for previous ones.</em>

Explanation:

In ecology, succession can be described as the changes in a species structure over a period of time. In a community, newer species tend to have better characteristics and adaptations to survive in a community as compared to the older ones. As a result, the new species begin to take over the land and the older ones gets removed. It is due to ecological succession that climax communities are formed from pioneer species.

What is the percent yield of NaCl if 31.0 g of CuCl2 reacts with excess NaNO3 to produce 21.2 g of NaCl?
IRISSAK [1]
Number of moles  CuCl₂ :

mass solute / molar mass

31.0 / 134.4520  => 0.230 moles of CuCl₂

Mole ratio :

CuCl₂ + 2 NaNO₃ = 2 NaCl + Cu(NO₃)₂<span> 
</span>
1 mole CuCl₂ -------- 2 moles NaCl
<span> 0.230 moles -------- ? moles NaCl
</span>
moles NaCl = 0.230 x 2 / 1

moles NaCl = 0.46 / 1

= 0.46  moles of NaCl ( molar mass 58.44 g/mol )

Mass of NaCl:

1 mole ---------- 58.44 g
0.46 moles ----- ( mass of NaCl in theory )

mass of NaCl = 0.46 x 58.44 / 1

mass of NaCl = 26.8824 / 1

= 26.8824 g of NaCl

<span>yield of NaCl :
</span>
NaCl produce / NaCl in theory  x 100 %

( 21.2 / 26.8824 ) x 100 

( 0.788 ) x 100 => 78.8 %

hope this helps!
