Toxaphene is a kind of pesticides used to protect crops specially cotton crops.
It is present in both solid and gas form.
It has a piney odor.
The physical appearance of toxaphene is yellow in colour amber waxy form.
It is an organochloride insecticide.
In 1940 it was manufactured.
It is a different composition of 670 chemicals.
According to questions,
Given,
Mass of toxaphene = 10^-5 gm
Mass of soil = 100 gm
Toxaphene soil concentrations = 10^-5 / 100 = 10^-7 gm/gm
1 gm/gm = 109 ppb
Concentration in units of ppb =10^-7 * 109 ppb = 100 ppb

UV exposure that leads to sunburn is proven in developing melanoma, the most dangerous of the three most common types of skin cancer.
It’s the water method that helps it
H2SO4(aq)+NaOH(s)----->NA2SO4 + H20
Answer:
2.82 L
T₁ = 303 K
T₂ = 263 K
The final volume is smaller.
Explanation:
Step 1: Given data
- Initial temperature (T₁): 30 °C
- Initial volume (V₁): 3.25 L
- Final temperature (T₂): -10 °C
Step 2: Convert the temperatures to Kelvin
We will use the following expression.
K = °C + 273.15
T₁: K = 30°C + 273.15 = 303 K
T₂: K = -10°C + 273.15 = 263 K
Step 3: Calculate the final volume of the balloon
Assuming constant pressure and ideal behavior, we can calculate the final volume using Charles' law. Since the temperature is smaller, the volume must be smaller as well.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 3.25 L × 263 K/303 K = 2.82 L
