Acid + alkali > salt + water
the acid and alkali neutralise each other
This was clear chemical reaction. The Potassium Chlorate reacted with Oxygen in a combustion reaction to change the chemical structure so that it was able to react with Silver Nitrate.
7=cells
9= The Central Nervous system

Having a definite volume but not a definite shape.
2 Na(s) + Cl₂(g) = 2 NaCl(s) 22,4 L in STP
Number of moles :
n = m / molar mass
Na = 103.0 / 22.98
Na = 4.48 moles
Cl₂ ( is limiting reagent )
13 L / 22,4 L = 0.580 moles Cl₂
2 ( Sodium stoichiometric coefficient)* 0.580 = 1.16 mol NaCl
Molar mass NaCl = 58.44 g/mol
1.16 * 58.44 = 67.7904 g of NaCl
hope this helps!
