Answer:
5.81L
Explanation:
N1 = 1.70 moles
V1 = 3.80L
V2 = ?
N2 = 2.60 moles
Mole - volume relationship,
N1 / V1 = N2 / V2
V2 = (N2 × V1) / N1
V2 = (2.60 × 3.80) / 1.70
V2 = 9.88 / 1.70
V2 = 5.81 L
The volume of the gas is 5.81L
<span>the change in entropy is positive and change in enthalpy is negative.and potential energy is lower.and the reason is materials in nature naturaly want to get stabler and more chaotic.
for the second question there is a big formula.Equilibrium θ=mcθ1(water)+mcθ1(metal) /mc(water)+mc(metal) just put numbers and it is easy to solve.equlibrium temperture is 23.5</span>
The answer to that would be connective tissue!
