well live in da Holocene period I hope dis helps :3
Answer:
N2
Explanation:
CO freezing point is -337 F
CO2 freezing point is -109 F
N2 freezing point is -346F
Answer:
Explanation:
The law of conservation of mass states that "mass in a system remains constant and that the mass of the product is remains the same as that of the reactants".
Law of conservation of energy states that "energy is neither created nor destroyed in the course of chemical or physical change but can be transformed from one form to another".
Let us properly write the equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
For the conservation of mass:
C has 1mole on both sides
H has 4mole on both sides
O has 4 mole on both sides
For energy, during combustion process, the methane CH₄ burns to liberate heat energy. This is an energy conversion process in which chemical energy in methane releases heat energy.
Answer:
3.8 cm
Explanation:
Given data
- Initial pressure (P₁): 3.2 atm
- Initial volume (V₁): 65 cm³
Volume of a sphere: V = 4/3 × π × r³ = 4/3 × π × (2.5 cm)³ = 65 cm³
- Initial temperature (T₁): 5.4°C + 273.15 = 278.6 K
- Final pressure (P₂): 1.0 atm
- Final temperature (T₂): 25.0°C + 273.15 = 298.2 K
We can find the final volume using the combined gas law.
The final radius of the bubble is:
V = 4/3 × π × r³
223 cm³ = 4/3 × π × r³
r = 3.8 cm
The Capillary effect means water can "climb" up thin tubes and water plants. This is due to the surface tension nature of water.
Hope this helps:)
