The Noble Gases are the most unreactive b/c its outermost shell completes the energy level and is stable enough.
Elements in the each group have the same number of valence electrons.
plz mark me as brainliest :)
Answer:
7.61 m/s backwards
Explanation:
Initial momentum = final momentum
0 = (880 kg) v + (12.4 kg) (540 m/s)
v = -7.61 m/s
The cannon's recoil is 7.61 m/s backwards.
As per question the initial states of the gases are given as
INITIAL STATE: FINAL STATE:
AS per combined gas equation obtained from the combination of Boyle's law and Charles law [Basic ideal gas laws]
Hence
=
=190.3 K [ANS]
