When fireworks go off, they produce smoke, which is evidence of a new substance being created.
b is fastest, having the lowest activation energy (35 kJ) and is an exothermic reaction, releasing energy in the form of heat
c is slowest, having the highest activation energy (55 kJ) and is an endothermic reaction, taking in energy from its surroundings
Molar mass:
KOH = 56.0 g/mol
Number of moles of KOH :
5.93 / 36.5 => 0.1624 moles
<span>KOH + HCl = KCl + H₂O
</span>
1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?
moles HCl = 0.1624 x 1 / 1
= 0.1624 moles of HCl
V ( HCl ) = moles / molarity
V(HCl) = 0.1624 / 0.183
V (HCl) = 0.887 L x 1000 = 887 mL
hope this helps!
