Answer:
P₂ ≅ 100 atm (1 sig. fig. based on the given value of P₁ = 90 atm)
Explanation:
Given:
P₁ = 90 atm P₂ = ?
V₁ = 18 Liters(L) L₂ = 12 Liters(L)
=> decrease volume => increase pressure
=> volume ratio that will increase 90 atm is (18L/12L)
T₁ = 272 Kelvin(K) T₂ = 274 Kelvin(K)
=> increase temperature => increase pressure
=> temperature ratio that will increase 90 atm is (274K/272K)
n₁ = moles = constant n₂ = n₁ = constant
P₂ = 90 atm x (18L/12L) x (274K/272K) = 135.9926471 atm (calculator)
By rule of sig. figs., the final answer should be rounded to an accuracy equal to the 'measured' data value having the least number of sig. figs. This means P₂ ≅ 100 atm based on the given value of P₁ = 90 atm.
Answer:
7,881 g/L
Explanation:
Iron volume = 30.58 mL - 29.40 mL = 1.18 mL
1.18 mL / 1000 mL = 0.00118 L
Iron density = mass/volume
= 9.3g / 0.00118 L
= 7,881 g/L
They turn blue litmus paper to red.
They also taste sour.
Explanation:
The two main categories of energy are potential energy (stored
energy) and kinetic energy (energy presently doing
work or causing change)...I hope this helps.
Na2So4 is the correct answer
