Gases take the shape of their container and have no definite volume because they can diffuse indefinitely. Answer C.
Answer:
Only Harry and Jena
Explanation:
Under federal regulations, an UST is any one or a combination of tanks such that the volume of an accumulation of regulated substances is 10% or more beneath the surface of the ground.
Any UST system holding a mixture of hazardous waste and other regulated substances are also are not covered by federal regulations regarding USTs.
Farm or residential tank of capacity more than 11 gallons used for storing motor fuel is covered by federal regulations regarding USTs.
According to the given question,
Only Harry and Jena are covered by federal regulations regarding USTs.
Oxygen to sulfur is less polar than comparable bonds to oxygen because sulfur is less electronegative than oxygen.
In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. Fluorine is the element with the greatest electronegative charge, whereas francium has a very low electronegative charge. Within a set of elements, electronegativity values drop from top to bottom. Moving from left to right along a period improves electronegativity. This is caused by a decrease in atomic size and a rise in nuclear charge, which allows a shared electron pair to be more attracted to one another.

The answer is labels on lead-based paint
Lead is highly toxic metal and it is very strong poison. Lead poising takes place when lead builds up in the body. A little amount of lead can also cause various health problems.
Labels on lead-based paint do not prevent lead poisoning as much as advised to not using such product.
Instead of using lead-based paint, people could use safer products such as titanium-white based paint, which is proved to be less toxic.
Thus, option (A) is correct answer i.e. labels on lead-based paint is not among the current strategies which is used to prevent lead poisoning.
