Answer:
So, I don't know if this is 100% correct, but, I believe it's <u><em>B.photosynthetic organisms to herbivores to carnivores and decomposers.</em></u> I'm so sorry if it's wrong!
Explanation: looked all over go ogle.
Have a good morning, afternoon, or night!

As given:
Initial moles of P taken = 2 mol
the products are R and Q
at equilibrium the moles of
R = x
total moles = 2 + x/2
Let us check for each reaction
A) P <-> 2Q+R
Here if x moles of P gets decomposed it will give 2x moles of Q and x moles of R
So at equilibrium
moles of P left = 2- x
moles of Q = 2x
moles of R = x
Total moles = (2-x) + 2x + x = 2 +2x
B) 2P <-> 2Q+R
Here x moles of P will give x moles of Q and x/2 moles of R
So at equilibrium
moles of P left = 2- x
moles of Q = x
moles of R = x/2
Total moles = (2-x) + x + x/2 = 2 + x/2
C) 2P <-> Q+R
Here x moles of P will give x/2 moles of Q and x/2 moles of R
So at equilibrium
moles of P left = 2- x
moles of Q = x /2
moles of R = x/2
Total moles = (2-x) + x + x = 2
D) 2P <-> Q+2R
Here x moles of P will give x/2 moles of Q and x moles of R
So at equilibrium
moles of P left = 2-x
moles of Q = x/2
moles of R = x
Total moles = (2-x) + x/2 + x = 2 + x/2
Answer:then he has a lot of gas
Explanation
A is correct. If an atom has more protons than electrons it is positively charged, if more electrons than protons it is negatively charged. An equal number of each will make it neutral
<span>Mass of KCl= 88.4g
</span>Molar mass of KCl=39+35.5
<span> =74.5
</span><span> The Moles of KCl= 88.4/74.5
</span> =1.186
<span>If for the 2 moles of KCl there are 3 moles of oxygen
</span>so
<span>1 mole of KCl will give=3/2=1.5 moles of oxygen
</span>
<span>1.186 moles of KCl will give =1.5*1.186=1.779 oxygen
</span><span>32 the molar mass of oxygen
</span>so its mass will be
<span>1.779 *32=56.928
</span>enjoy
