Answer:

Unbalanced= Fe + H2SO4 Fe2(SO4)3 + H2

Balanced with same coefficients in the same order= 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2

Explanation:

Balancing a chemical equation means having the same number of atoms of an element on the reactant side as on the product side in accordance to the law of conservation of mass. To do this, coefficients (number behind the element) are used.

In this question,the below balanced equation was given

2CO2 + 3H20 ---> C2H6O + 3O2

Four other unbalanced equations were also given to be balanced and see which will have the same coefficients in the same order as the template equation. Let's start balancing each equation.

1. FeCl3 + NH4OH ---> Fe(OH)3 + NH4Cl (unbalanced)

Atoms of nitrogen, hydrogen, oxygen and Chlorine are unequal in both sides. Hence, we have

FeCl3 + 3NH4OH ---> Fe(OH)3 + 3NH4Cl (balanced)

2. CH4 + O2 ---> CO2 + H2O (unbalanced)

Atoms of hydrogen and oxygen are unequal in both sides. We have;

CH4 + 2O2 ---> CO2 + 2H2O (balanced)

3. Fe + H2SO4 ---> Fe2(SO4)3 + H2 (unbalanced)

Atoms of iron, sulphur, and oxygen are unequal in both sides. Hence,

2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 (balanced)

4. PCl5 + H2O ---> HCl + H3PO4 (unbalanced)

Atoms of chlorine, hydrogen, and oxygen are unequal in both sides. Hence,

PCl5 + 4H2O ---> 5HCl + H3PO4 (balanced).

From the above balanced equations, it can be observed that; 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 has the same coefficients in the same order as 2CO2 + 3H20 ---> C2H6O + 3O2

That is, coefficient 2---- 3 ---- 1 ----- 3.

Taking into accoun the law of conservation of matter, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

In first place, you have the balanced equation:

2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

The coefficients of the balanced reaction in order are: 2 -3- 1- 3

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Considering the law of conservation of matter, you must balance the chemical equation.

For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

On the other side the coefficients located in front of each molecule indicate the amount of each compound for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Considering what was expressed above and the reactions given, the following balanced reactions are obtained:

The coefficients of each balanced reaction in order are:

Finally, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

Below image is the phylogenetic tree for the four sequences.

A phylogenetic tree is a branching diagram or a tree that depicts the evolutionary relationships among different biological species or other entities based on similarities and differences in their physical or genetic traits. It is also known as an evolutionary tree or phylogeny. A single phylogenetic tree that represents the common ancestry of all life on Earth.

Each node in a rooted phylogenetic tree reflects the inferred most recent common ancestor of each descendant, and in some trees, the edge lengths can be interpreted as time estimates. The term "taxonomic unit" refers to each node. Due to their inability to be physically observed, internal nodes are typically referred to as hypothetical taxonomic units.

In biological disciplines like bioinformatics, systematics, and phylogenetics, trees are helpful. Unrooted trees don't require knowledge of or inference from the ancestral root; they just show how the leaf nodes are linked.

The statement "Earthquakes often form at plate boundaries" is true about the formation of earthquakes.

The root cause behind earthquakes lies within tectonic plate action. Whenever two or more of these massive pieces of Earths surface clash together or slide parallel to each other it sometimes results in them becoming wedged together - thereby increasing stress at their touchpoints until they abruptly break apart via seismic energy release.

This process creates seismic waves which travel outward from their epicenter through our planets surface while causing local vibrations along the way.

The most accurate statement that explains the difference between heart cells and liver cells in terms of their production of the protein cardiac myosin is "Heart and liver cells express different genes."

In multicellular organisms, different cell types have specific functions and characteristics that are determined by the genes they express. Genes are segments of DNA that contain the instructions for producing specific proteins. Each cell type expresses a unique set of genes that enable them to carry out their specialized functions.

In the case of heart cells and liver cells, they have different gene expression profiles. Heart cells specifically express the genes responsible for producing cardiac myosin, a protein essential for the contraction of the heart muscle. This allows the heart to effectively pump blood throughout the body.

On the other hand, liver cells do not express the genes for cardiac myosin production, as the liver has different functions unrelated to heart muscle contraction. The statement that heart cells contain different genes from liver cells is essentially expressing the same idea. Heart cells and liver cells have distinct gene expression patterns, leading to the production of different proteins and ultimately different cellular functions.

Both heart cells and liver cells utilize DNA as the genetic material that contains the genes responsible for protein production. RNA molecules are transcribed from DNA and play a crucial role in protein synthesis, but the distinction between heart and liver cells lies in the specific genes they express, not the reliance on different genetic materials.

A 45% CaCl2 Solution has a mass of 67.4 g of CaCl2 and contains 45 g of solute per 100 mL of solution.

The formula for mass concentration is mass of solute (g)/volume of solution (L)

100 mL of solution is equal to 100 * 1 L/1000, or 0.1 L.

45 g/0.1 L of the solution's mass equals 450 g/L.

Mass concentration divided by molar mass gives a solution's molar concentration.

CaCl2's molar mass is 111 g/mol.

450 g/L / 111 g/mol = 4.05 mol/L is the molar concentration.

Number of moles of CaCl2 in 150 ml of a 4.05 mol/L solution is equal to the molar concentration times the volume (L). For example, 4.05 * 150 * 1 L/1000 equals 0.6075 moles of CaCl2.

Number of moles * Molar Mass = mass of CaCl2 present in 0.6075 moles = 0.6075 * 111 = 67.4 g of CaCl2.

b). At least two intron must be present in gene Y

c). It is impossible to determine whether there are any introns in gene Z.

Explanation:

Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.

In the context, we get :

a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.

b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.

Answer:

The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.
