Row or periods have in common is the valence electron count. The valence electron count goes up as you move across the periodic table. Also atomic size gets smaller as you move from left to right
Answer:
The soil has a percentage of water by mass of 27.8 %.
Explanation:
Keeping in mind that
- Mass of Clay = Mass of water + Mass of Dry Soil
we can <u>calculate the mass of water</u>:
- 1350 g = Mass of Water + 975 g
We can then <u>calculate the mass percentage of water in the soil</u>:
- 375 / 1350 * 100% = 27.8 %

Answer:
112 L
Explanation:
Since the pressure is being held constant, you can use the following variation of the Ideal Gas Law to find the new volume:

In this equation, "V₁", "T₁", and "N₁" represent the initial volume, temperature, and moles. "V₂", "T₂", and "N₂" represent the final volume, temperature, and moles.
V₁ = 87.2 L V₂ = ? L
T₁ = 425 K T₂ = 273 K
N₁ = 2.5 moles N₂ = 2.5 + 2.5 = 5.0 moles
