First, let's compute the number of moles in the system assuming ideal gas behavior.
PV = nRT
(663 mmHg)(1atm/760 mmHg)(60 L) = n(0.0821 L-atm/mol-K)(20+273 K)
Solving for n,
n = 2.176 moles
At standard conditions, the standard molar volume is 22.4 L/mol. Thus,
Standard volume = 22.4 L/mol * 2.176 mol =<em> 48.74 L</em>
Answer:
predation
Explanation:
Predation An interaction in which one organism kills another for food. Prey An organism that is killed and eaten by another organism.
In order to balance this, you have to count each
element where the elements in the reactants side and the product side should
have equal number of molecules. The balanced reaction is as follows:
2HCl + Ca(OH)2 = CaCl2 + 2H2O
Yes. The model represents atoms rearranging to produce a new compound.
<h3>What chemical reactions?</h3>
They are reactions involving the breakage of bonds and rearrangement of atoms in reactants to form products.
In the model, the bonds between hydrogen and chlorine were broken. Thereafter, each hydrogen and chlorine molecule linked up to form hydrogen chloride.
Thus, the model shows atoms rearranging to produce a new compound.

#SPJ1
Answer:
F
Explanation:
Halogens may interact with the benzene ring via inductive or resonance effects. Halogens deactivate the benzene ring by inductive effect rather than by resonance effects.
The lone pairs of electrons present on the halogen atoms may be donated to the ring by resonance, but an opposite effect, the inductive pull (-I inductive effect) of the halogen atoms on electrons away from the benzene ring due to the high electro negativity of the halogens leads to a deactivation of the ring towards electrophilic substitution.
Hence inductive electron withdrawal by the halogen atom predominates over electron donation by resonance effect and the benzene ring g is deactivated towards electrophilic substitution at the ortho and para positions.
