If the pressure increases to 300 KPa and the volume remain constant the temperature will be
900K
it is calculated using the gays lussac law formula that is P1/T1=P2/T2
P1= 100Kpa
p2=300Kpa
T1=300k
T2=?
by making T2 the subject of the formula T2 =P2T1/P1
=300KPa x300 k/100 kpa = 900 K
Answer:
D they are quickly replenished. I get this question a good bit so i know the answer.
Explanation:
Carbon 14 because it has an approximate half life of 5000 years.
NaBr gives fully seperated ions as Na⁺(aq) and Br⁻(aq) while AgBr gives partially dissociated ions as Ag⁺(aq) and Br⁻(aq).
NaBr(aq) →Na⁺(aq) + Br⁻(aq)
0.200 0.200
AgBr(s) ⇄ Ag⁺(aq) + Br⁻(aq)
Initial - -
Change -X +X +X
Equilibrium X X
Ksp = [Ag⁺(aq)] [ Br⁻(aq)]
7.7 × 10⁻¹³ = X * (0.200 + X)
7.7 × 10⁻¹³ = X² + 0.200X
0 = X² + 0.200X-7.7 × 10⁻¹³
X1 = 3.8 x 10⁻¹²
X2 = -0.2
X = molar solubility of AgBr.
hence, X cannot be a negative value.
molar solubility of AgBr is 3.8 x 10⁻¹² M.
