Is change in atmospheric co2 levels likely to impact marine life

1 answer:

4 0

The addition of carbon dioxide to the atmosphere takes place due to human activities like the burning of fossil fuels. The oceans play an essential role in maintaining the carbon cycle of the Earth in balance. With the elevation of carbon dioxide in the atmosphere, more absorption of carbon dioxide takes place by the oceans.

In the ocean, carbon dioxide reacts with seawater to produce carbonic acid, this ultimately leads to an increase in acidity of seawater, also known as ocean acidification.

With the increase in acidity, it becomes tougher for corals to construct skeletons and for shellfish and other creatures to manufacture the shells they require for protection. The corals are mainly essential as they offer habitation to various sea creatures.

Methane gas and oxygen gas react to form water vapor and carbon dioxide gas. What volume of water would be produced by this reac

yanalaym [24]

volume of H₂O = 7.2 L

Explanation:

The combustion reaction of methane (CH₄):

CH₄ + 2 O₂ → CO₂ + 2 H₂O

Now we calculate the number of moles of methane using the following formula:

number of moles = volume / 22.4 (L/mole)

number of moles of CH₄ = 3.6 / 22.4

number of moles of CH₄ = 0.16 moles

Taking in account the chemical reaction, we devise the following reasoning:

if 1 mole of CH₄ produce 2 moles of H₂O

then 0.16 moles of CH₄ produce X moles of H₂O

X = (0.16 × 2) / 1 = 0.32 moles of H₂O

And now we can calculate the volume of water (H₂O) produced by the reaction:

number of moles = volume / 22.4 (L/mole)

volume = number of moles × 22.4 (L/mole)

volume of H₂O = 0.32 × 22.4

volume of H₂O = 7.2 L

Which element is most likely to form a cation? <br> sodium, silicon, sulfur, argon

Harrizon [31]

<h3>Answer:</h3>

Sodium

<h3>Explanation:</h3>

To answer the question we need to know a few things.

What are cations?

Cations are positively charged ions that are formed when an atom of an element loses an electron(s).

What elements form cations?

Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
For example, alkali metals such as sodium form cations with a charge of +1.
In this case, sodium will form a cation with a charge of + 1, Na⁺

What are negatively charged ions?

Negatively charged ions are known as anions.
They are formed by non-metallic elements such as sulfur, argon, silicon, etc.
