Empirical formula for H2Cl2O6, Tetraphosphorus decoxide, Iron(III) phosphate and C6H12O2

HClO₃

Explanation:

Empirical formula of a chemical compound is defined as the simplest ratio of atoms presents in the compound (In whole numbers).

For the H₂Cl₂O₆ the empirical formula could be obtained dividing in 2 the formula. That is:

HClO₃ → This is the simplest ratio of atoms presents in the compound, that is, the empirical formula

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
