Answer:

Because the way the earth is titled the sun doesn't shine on them at the same time

The north pole is in constant daylight! When the northern half of Earth is tilted toward the Sun, the southern hemisphere is tilted away. People in the southern hemisphere experience the shorter day lengths and colder temperatures of winter. ... The seasons are not caused by how far Earth is from our Sun.

Ancient cyanobacteria released ______, which assisted in creating the atmosphere as we know it today.
andrey2020 [161]

Answer;

- Oxygen

-Ancient cyanobacteria released oxygen, which assisted in creating the atmosphere as we know it today.

Explanation;

-The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras.

-Cyanobacteria are aquatic and photosynthetic, meaning they live in the water, and can manufacture their own food. During the process of photosynthesis, energy from sunlight is used together with carbon (iv) oxide and water to form organic molecules that serve as nutrients for the organisms and also oxygen gas is released to the atmosphere.

Which chemical equation is balanced to show that mass is conserved during the reaction? *
Mazyrski [523]

Answer:

B  

Step-by-step explanation:

Equation B is balanced. It has four atoms of H and four of O on each side of the reaction.

A is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.

C is <em>wrong</em>. It has two atoms of O on the left and four on the right.

D is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.

Ainat [17]

Imidazole's cyclic structure is aromatic and the lone pair present at the N₁ atom available for donation. hence, according to question N₁ is the most basic atom in the structure.

<h3>What is resonating structure?</h3>
  • Two π bonds (between C₂-C₃ and N₁-C₅), as well as one lone pair on N₄, can interact with one another to generate a delocalized π system in the cyclic structure.
  • This delocalization is intriguing since it has the same number of delocalized electrons as benzene—six.
  • As a result, imidazole, like benzene, has a closed, delocalized ring with six π electrons. So, like benzene, it is regarded as an aromatic chemical with resonance stability.
  • N₄ is neutral since it cannot be donated because it needs to use its lone pair to be aromatic.
  • On the other hand, N₁ already forms a π connection, which helps the system become delocalized.
  • N₁ is sp² hybridized and has a trigonal planar basic form. Its lone pair cannot communicate with the delocalized π system since it is pointed away from the cyclic structure.
