Question 27

elements that are gases, or are brittle solids, and are poor conductors at room temperature are

a)metals

b)nonmetals

c)metalloids

d)isotopes

Elements that are gases, or are brittle solids, and are poor conductors at room temperature are nonmetals

Explanation:

Elements that are usually gases or solids and are poor conductors at room temperature.

Metals not an option, because they aren't gasses. Most metals have a characteristic lustre and are good conductors of heat and electricity, at room temperature.

Metalloids are unique because they have properties of both metals and non-metals. But, most metalloids are poor conductors of heat and electricity. Metalloids aren't an option either.

Every element has isotopes. They can be gasses, solids,.. Can be good or bad conductors. Isotopes isn't an option either.

Solid nonmetals are not malleable or ductile, but brittle or powdery. Nonmetals are poor conductors of heat and electricity, because electrons are not free to move.

Elements that are gases, or are brittle solids, and are poor conductors at room temperature are nonmetals

answer; i believe the answer is hydraulic action;

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
