Answer: Graphite is nonpolar carbon which associates with the nonpolar hexanes. The cellulose in the exposed paper contains polar regions that are attracted to the polar water.
Explanation:
Answer:
0.5077 moles
Explanation:
Data Given:
Moles = n = <u>???</u>
Temperature = T = 300 K
Pressure = P = 380 mmHg = 0.50 atm
Volume = V = 25 L
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹
Solving Equation for n,
n = P V / RT
Putting Values,
n = (0.50 atm × 25 L) / (0.082057 atm.L.mol⁻¹.K⁻¹ × 300 K)
n = 0.5077 moles
The equation is L = m/M
First, covert 10. grams of AgNO3 to moles which is 0.059 moles.
Divide 0.059 moles by 0.25M which is 0.24 liters.
Although soils are capable of resisting pH changes, there are some circumstances where the pH of the water can result in alterations.
<h3>Will Soil pH Be Affected by Water pH?</h3>
The texture of soil affects how susceptible it is to the pH of the surrounding water. Smaller soil particles, such as clays and clay loams, have a greater impact than larger, sandier soils. There are more colloids, which are extremely minute particles, in fine-textured soils. Positively charged ions are maintained at these colloids. The cation exchange capacity of a soil refers to its capacity to hold onto these ions. Ions on the colloidal particles trade places with ions in the soil solution. The pH of the soil is less affected by negative ions in the soil solution.
