Answer: bacteria, archaea, plants, protists, animals, and fungi
Explanation: Throughout the history of evolution, cellular respiration has been a central element of many organisms' functioning. Even as species have developed and changed through the process of natural selection, all of the successful, surviving individuals have kept the genes that allow them to produce the enzymes needed for cellular respiration.
Answer:
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
Example: For the given chemical equation:
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms which is a conjugate acid.
Thus the chemical symbol that is commonly used to represent a "proton" in the context of Bronsted-Lowry acids and bases is
There is a missing portion of this question which shows the reaction that needs balancing:
"In a balanced equation, the same number of each kind of atom is shown on each side of the equation. Calculate the number of iron (Fe), oxygen (O), and carbon atoms (C).
Fe2O3+ 3CO --> 2Fe + 3CO<span>2
</span><span>Based on these values, is the equation balanced?</span><span>"
</span>
To check if this equation is balanced we simply compare the number of each element on each side of the equation.
On the reactant side of the equation we have:
2 Fe atoms
6 O atoms
3 C atoms
On the product side of the equation we have:
2 Fe atoms
6 O atoms
3 C atoms
Therefore, both side of the reaction have the correct and equal number of each atom, so the equation is balanced.
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by
For a general chemical reaction:
The is written as:
There are 3 conditions:
- When ; the reaction is product favored.
- When ; the reaction is reactant favored.
- When ; the reaction is in equilibrium.
At equilibrium, the ratio of concentration of reactants to the concentration of products is equal to 1.
At equilibrium, the rate of forward reaction is equal to rate of backward reaction.
Hence, the correct answer is Option D.
