From the equation above the reacting ratio of KClO3 to O2 is 2:3 therefore the number of moles of oxygen produced is ( 4 x3)/2 = 6 moles since four moles of KClO3 was consumed
mass=relative formula mass x number of moles
That is 32g/mol x 6 moles =192grams
For the answer to the questions above,
a) Ag2CO3(s) => Ag2O(s)+CO2(g)
<span>b) Cl2(g)+2(KI)(aq) => I2(s)+2(KCl)(aq) (coefficients are for balanced equation) </span>
<span>net ionic is Cl2(g)+2I- => I2(s)+2Cl-(aq) </span>
<span>c) I2(s)+3(Cl2)(g)=>2(ICl3)
</span>I hope I helped you with your problem
Answer:
Increases
Explanation:
As ice melts into liquid water, the kinetic energy of the particles increases.
This is because to melt ices, heat energy is supplied.
- The sum total of all the average speed of the particles in a substance is the heat energy.
- Heat is a form of kinetic energy.
- As more heat is added, the particles moves rapidly and the kinetic energy increase.
