25 kj absorbed by dissolving 1 mole of NH4NO3
1kj is absorbed by dissolving = 1/25.7 = 0.03891 moles
what about 73 kj absorbed by dissolving
0.03891 x73= 2.8404 moles
<span>The
Pair Of Compounds that Are Isomers are CH3COCH3 and CH3CH2CHO. The answer is
number 4. Isomers have the same formula but different structures. In number 4,
both compounds contains three carbon atoms, one oxygen and 6 hydrogen atoms
that makes them isomers.</span>
Answer:
The protons and electrons in each element are equal. The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons. 16 neutrons
Explanation:
Answer:
Reaction quotient, Q, is 0.44
Explanation:
For the reaction:
C(s)+H₂O(g) ⇌ CO(g)+H₂(g)
Reaction quotient Q, at any course of the reaction, is defined as:
Q = [CO][H₂] / [H₂O]
Concentration of reactants is:
[CO] = 3.20mol / 3.75L = 0.853M
[H₂] = 8.20mol / 3.75L = 2.187M
[H₂O] = 15.9mol / 3.75L = 4.24M
Replacing, Q is:
Q = [0.853][2.187] / [4.24]
<em>Q = 0.44</em>
