Answer:
c) spontaneous
Explanation:
According the equation of Gibb's free energy -
∆G = ∆H -T∆S
∆G = is the change in gibb's free energy
∆H = is the change in enthalpy
T = temperature
∆S = is the change in entropy .
And , the sign of the ΔG , determines whether the reaction is Spontaneous or non Spontaneous or at equilibrium ,
i.e. ,
if
- ΔG < 0 , the reaction is Spontaneous
- ΔG > 0 , the reaction is non Spontaneous
- ΔG = 0 , the reaction is at equilibrium
From the question ,
The value for ΔG is negative ,
Hence ,
ΔG < 0 , the reaction is Spontaneous
Answer:
0.502mol
Explanation:
The balanced chemical equation of the reaction described in this question is as follows:
2KClO3 → 2KCl+ 3O2
According to the equation above, 2 moles of KClO3 will produce 2 moles of KCl.
Using mole = mass/molar mass to convert mass of KClO3 to moles
Molar mass of KClO3 = 39 + 35.5 + 16(3)
= 39 + 35.5 + 48
= 122.5g/mol
mole = 61.5 g ÷ 122.5g/mol
mole = 0.502mol
Since 2 moles of KClO3 will decompose to produce 2 moles of KCl.
0.502 mol of KClO3 will decompose to produce 0.502 × 2/2
= 0.502mol of KCl.
In short, I’d say the answer is C.
In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.
<h2>
Reacting Substances</h2>
To determine what would occur when two substances react, we must identify their charges.
There is what's called the criss-cross method where we put the substances with their charges side by side, and criss-cross their charges to get the number of atoms there are for each substance.
<h2>Solving the Question</h2>
We're given:
Mg has a charge of +2 and Cl has a charge of -1:
⇒
Criss-cross the charges:
⇒
Therefore, for every 1 atom of magnesium, there would be 2 atoms of chlorine.
<h2>Answer</h2>
For every 1 atom of magnesium, there would be 2 atoms of chlorine.
