Answer:
C when lungs expand they fill with air from the atmosphere
Slicing carrotsin a chemical reacționat the reactants, which are on the left side of the equation should become something else which are the products on the right side of the equation!
You get nothing but also carrot when slice it up but for example frying an egg due to the heat, chemical energy, you get scrambled egg or whatever!
Answer:
4.78 g/cm³
Explanation:
Density is expressed as mass per unit volume:
D = m/V
D = (24.02 g) / (5.02 mL) = 4.78 g/mL
The density should be expressed in g/cm³, so mL must be converted to cm³. The conversion ratio is 1 mL = 1 cm³.
(4.78 g/mL)(1 mL/1 cm³) = 4.78 g/cm³
Data Given:
Initial Volume = V₁ = 36.7 L
Initial Pressure = P₁ = 145 kPa
Initial Temperature = T₁ = 65 °C + 273 = 338 K
Final Volume = V₂ = ?
Final Pressure = P₂ = 101.325 kPa (Standard Pressure)
Final Temperature = T₂ = 273 K (Standard Temperature)
Formula used:
As number of moles are constant, so Ideal Gas equation in following form is used,
P₁ V₁ / T₁ = P₂ V₂ / T₂
Solving for V₂,
V₂ = P₁ V₁ T₂ / T₁ P₂
Putting Values,
V₂ = (145 kPa × 36.7 L × 338 K) ÷ (273 K × 101.325 kPa)
V₂ = 1798667 ÷ 27661.25
V₂ = 65.02 L
