7. A

The energy pyramid is simply going from the bottom having the most energy, and the top having the least. The most energy in the energy pyramid is provided by the producers. The producers are at the bottom of the energy pyramid. They are the basis of all ecosystems. The producers have the most energy because they are the ones that manage to produce food for themselves, thus they provide 100% energy, while all other levels have 10% of the previous level of the energy pyramid.

8. coyote

The trophic levels are simply divided into autotrophs, which are the ones that produce the food for themselves, primary consumers, which are feeding on the producers, and secondary consumers, which are feeding on the primary consumers. In the category of secondary consumers we have the predators. The predators are the ones that eat the primary consumers, and the coyote is falling into this category. The coyote is a predator, from the canidae family, being a carnivore that preys upon herbivores.

9. True

The invasive species are the species that have managed to reach and inhabit places that are not their native territory. This can happen in a natural way, or because of the humans. The invasive species are usually much more competitive than the native species. They manage to take their food sources, prey upon them with ease, reproduce much quicker, as well as introducing new diseases. All of that results in in easy expansion of the invasive species, while the native species decrease or even go extinct.

10. It would decrease because the greenfly population would decrease

The ladybird, or ladybug, is falling into the category of secondary consumers, thus they are predators. They feed upon small insects, mostly that are considered as pests, such as the greenfly. The greenfly is feeding on the berries. If the berry population starts to decrease, then the greenfly population will decrease as well, as the food source will be smaller. The ladybird population will too start to decrease, as the greenfly population, its prey, will be decreasing because of the decrease in the berry population.

Consider the following reaction. Zn(s) 2agno3(aq) --> 2ag(s) zn(no3)2(aq)when 16. 2 g of silver was produced, _____ mole(s) o
Crazy boy [7]

The required amount of silver nitrate to produce 16.2g of silver is 25.48 grams.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

Moles of silver = 16.2g / 107.8g/mol = 0.15mol

From the stoichiometry of the given reaction it is clear that, same moles of silver nitrate is required to produce same moles of silver. So 0.15 moles of silver nitrate is required.

Mass of silver nitrate = (0.15mol)(169.87g/mol) = 25.48g

Hence required mass of silver nitrate is 25.48g.

The following equation represents the type of reaction called
Mazyrski [523]

Answer:

Reduction

Explanation:

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Mn⁺⁷ +3e⁻    →    Mn⁴⁺

Mn gets three electrons , its oxidation state reduced from +7 to +4 so Mn gets reduced.

Examples:

Consider the following reactions.

4KI + 2CuCl₂  →   2CuI  + I₂  + 4KCl

the oxidation state of copper is changed from +2 to +1 so copper get reduced.

CO + H₂O   →  CO₂ + H₂

the oxidation state of carbon is +2 on reactant  side and on product side it becomes  +4 so carbon get oxidized.

H₂S + 2NaOH → Na₂S + 2H₂O

The oxidation sate of sulfur is -2 on reactant side and in product side it is also -2 so it neither oxidized nor reduced.

Vaselesa [24]

Answer: 1.6L

Explanation:

V1 = 1.50 L,

V2 =?

n1 = 3mol

n2 = 3 + 0.2 = 3.2mol

From PV = nRT

V1 /n1 = V2/n2

1.5/3 = V2 /3.2

V2 = (1.5/3/) x 3.2 = 1.6L
