Silicon is your answer i hope this helps
neonofarm [45]3 years ago

Answer: Silicon is classified as a metalloid.

Metalloids are those elements which have properties of metals as well as non-metals. This means that they are intermediate of metals and non-metals. They are also called as semimetals.

Silicon is the typical example of a metalloid. The physical property that it is lustrous is similar to metals, whereas it is easily cracked, therefore, it is brittle like non-metals.

Thus, it is classified as a metalloid.

Waters high heat protects organisms in ocean from what
Alja [10]

Answer:

Water's high specific heat allows it to absorb a large amount of heat without changing much in temperature, keeping a relatively constant temperature in oceans and lakes which is beneficial to marine life. If water did not have a high specific heat, then it would increase in temperature very quickly and oceans and lakes would have drastic changes in temperature in very short periods of time. This could harm or kill the organisms living in them.

using the equation cs2+3o2=co2+2so2 what is the percent yield of so2 if the burning of 12.5g of cs2 produces 15.12 g of SO2
vesna_86 [32]
<h3><u>Answer;</u></h3>

  = 71.96%

<h3><u>Explanation</u>;</h3>

1 mole of CS2 = 76.133 g

1 mole of SO2 = 64.06 g

1 mole of CS2 reacts with 3 moles of Oxygen to produce 2 moles of SO2

Moles of CS2 in 12.5 g = 12.5/76.133

                                      =  0.164 moles

Mass of SO2 = 0.164 mol × 2 × 64.06

                      = 21.01168 g

Therefore;

Percentage yield of SO2

  = 15.12/21.01168 × 100%

<u>   = 71.96%</u>

Describe the effects of succession has on genetic diversity​
Scorpion4ik [409]

Answer:

Succession is the natural evolution that occurs in an ecosystem by its own internal dynamics, that is, it refers to two stages of something that is (precisely) successive in time.

Explanation:

Genetic diversity occurs at various levels of the organization of the ecosystem, through the species that compose it, from its subspecific populations (provenances), family groups and individual genotypes, down to the molecular level of the gene. A succession consists of the process of change that an ecosystem undergoes over time, as a consequence of changes that occur both in the conditions of the environment and in the populations that comprise it, giving rise to an increasingly organized and complex ecosystem. The effects of a succession are the change in the structure and dynamics of an ecosystem over time, as a result of an interaction of physical forces that break in from the outside and development processes generated within the system. Also when the classes of ecological changes are controlled by the community, changes will occur in the physical substrate and the microclimate, altering the composition of species and diversity as a result of competition and other interactions of the populations. Species diversity tends to increase with succession, the species undergo mutations or transformations, given that the soil, air and even water (abiotic factors) have also undergone important transformations during the succession.

What is the condition in which the inner layers of arteries become irregular and thick due to the accumulation of plaque?
Sliva [168]

Answer:Atherosclerosis

Explanation:

It is the condition in which the patcy deposits of the fatty materials forms in the walls of the medium sized and large arteries which reduces the blood flow in the artery.

It is the problem associated with the people eating more fatty food. The cholesterol of such people also increases and having a blockage can be dangerous sign as it can lead to heart attack at later stages.
