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

Answer:
C. HCI(g)
Explanation:
The following equation between hydrogen gas (H2) and oxygen gas (O2) is given below:
H2(g) + Cl2(g) ►
Based on these unbalanced equation, the products of the reaction was not given, however, if one molecule of hydrogen and oxygen combine, hydrogen chloride (HCl) should be produced as the product of the reaction as in:
H2(g) + Cl2(9) ► 2HCl(g)
Answer:
B
Explanation:
The two compounds have different physical properties and different chemical properties despite the fact that they are formed from nitrogen and oxygen.
