A Bunsen burner usually burns methane gas (CH4) using words, write the chemical equation for this reaction.

The general chemical equation for the complete combustion (or burning) of some hydrocarbon fuel is, in words, as follows:

hydrocarbon fuel and oxygen gas react to produce carbon dioxide gas and water vapor,

or, using chemical notation,

where

Don't worry if that looks daunting. In our case, we are given the identity of the fuel (methane, or CH₄), so our equations will be straightforward.

In words: Methane gas and oxygen gas react to produce carbon dioxide gas and water vapor (or methane gas + oxygen gas → carbon dioxide gas and water vapor).

In chemical notation:

idk what is it? is this a question that you know the answer or u dont

(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
