Why is a pyramid shape used to represent the energy in an Ecosystem?​
Salsk061 [2.6K]

Answer:

An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

Which two changes would make this reaction favor the formation of products? 2502 +02= 2503 + energy A. Raising the temperature B
Alisiya [41]

C. Decreasing the temperature

D. Raising the pressure​

<h3>Further explanation</h3>

Given

Reaction

2SO₂+O₂⇔2SO₃+energy

Required

Changes to  the formation of products

Solution

The formation of SO₃ is an exothermic reaction (releases heat)

If the system temperature is raised, then the equilibrium reaction will reduce the temperature by shifting the reaction in the direction that requires heat (endotherms). Conversely, if the temperature is lowered, then the equilibrium shifts to a reaction that releases heat (exothermic)  

While on the change in pressure, then the addition of pressure, the reaction will shift towards a smaller reaction coefficient  

in the above reaction: the number of coefficients on the left is 3 (2 + 1) while the right is 2

As the temperature decreases, the equilibrium will shift towards the exothermic reaction, so the reaction shifts to the right towards SO₃( products-favored)

And increasing the pressure, then the reaction shifts to the right SO₃( products-favored)⇒the number of coefficients is greater

7 Which physical characteristic of a solution may
Nuetrik [128]

Answer:

2= its color

Explanation:

Transition elements are present in the middle of periodic table. These are d-block elements.

These are 38 elements.

All transition elements have partially filled d orbitals.

They showed color in compound because of d-d transition.

During the d-d transition electron absorbed the energy and emit the reminder energy. The emission is usually in the form of color light.

The color of ion is complementary to the absorbed color.

The transition elements are used as a catalyst in industries such as polymer, petroleum industries.

They are ductile, conduct heat and electricity.
