The mass of HNO3 will be 17.8 kg.
Further Explanation:
More than one element bonded together is known as a compound.Sum of total mass of molecule measure in gram which constitutes the atom of molecule known as molar mass. Gram per mole is an S.I. unit of molar mass.Molarity of a solution define as the number of moles of solute per litre solution.
For the provided reaction:
[tex]4{\text{N}}{{\text{O}}_2}({\text{g}})+{{\text{O}}_2}({\text{g}})+2{\text{N}}{{\text{O}}_2}({\text{l}})\to4{\text{N}}{{\text{O}}_3}({\text{aq}})[/tex]
Oxygen and water found in abundance. So, the NO2 is known as a limiting reagent as it is responsible for limiting the product formation. The moles of NO2is calculated with the help of the formula:
[tex]\begin{gathered}{\text{Number of moles=}}\frac{{{\text{given mass}}}}{{{\text{molar mass}}}}\hfill\\\begin{array}{*{20}{l}}{{\text{Given mass }}=14{\text{ kg}}=14000{\text{ grams}}}\\{{\text{Molar mass}}=46{\text{g/mol}}}\end{array}\hfill\\\end{gathered}[/tex]
Inserting the values in the formula,
[tex]\begin{aligned}{\text{Moles of N}}{{\text{O}}_2}=\frac{{14000}}{{46}}\\=304.34\end{aligned}[/tex]
By the help of Stoichiometry,
4 moles of NO2 will generate 4 moles of HNO3
This means that 304.34 moles of will generate,
[tex]\begin{gathered}=\frac{4}{4}\times304.34\hfill\\=304.34\hfill\\\end{gathered}[/tex]
In order to calculate the mass of HNO3, first equation can be used and we will get,
[tex]\begin{aligned}{{\text{Molar mass of HN}}{{\text{O}}_3}&={\text{ }}63{\text{ g/mol}}}\\{&=304.34\times63}\\{&=19173.42\text{ g}{\text{ or }}19.17{\text{ Kg}}}\end{aligned}[/tex]

The mass of HNO3 that can form from the given amount of NO2 pollutant is 19.24 kg.
Explanation:To find the mass of HNO3 that can form from the given amount of NO2, we need to use stoichiometry and the balanced equation for the reaction.
From the balanced equation: 4 mol NO2: 4 mol HNO3
To convert the given mass of NO2 to moles, we need to divide by the molar mass of NO2:
14 kg NO2 * (1 mol NO2 / 46.0055 g NO2) = 0.304 mol NO2
Therefore, using stoichiometry, the 0.304 mol NO2 will react to form 0.304 mol HNO3.
To find the mass of HNO3, we can use the molar mass of HNO3:
0.304 mol HNO3 * (63.01284 g HNO3 / 1 mol HNO3) = 19.24 kg HNO3

what is the energy released during cell respiration
How do you think the amount of light affects how plants grow
The amount of light greatly affects how plants grow through photosynthesis. Insufficient or excessive light can have negative effects on plant growth. Different plants have different light requirements.
Explanation:In biology, the amount of light greatly affects how plants grow through the process of photosynthesis. Photosynthesis is the process by which plants convert light energy into chemical energy, in the form of glucose, which is used for growth and development. Light provides the energy needed for this process to occur. Plants need a certain amount of light to thrive and grow properly.
For example, insufficient light can lead to weak, spindly stems and pale, small leaves, while excessive light can cause leaf burn and other damage. Plants have different light requirements depending on the species. Some plants, like cacti, can survive and grow in low light conditions, while others, like sunflowers, require full sun to thrive. Understanding a plant's light needs is important for successful cultivation.

Plates move apart at ____ boundaries. a. convergent c. divergent b. stable d. transform
Plates move apart at divergent boundaries. Divergent boundaries are locations where tectonic plates are pulling away from each other.
The correct option is C.
At divergent boundaries, tectonic plates move apart from each other. This movement is driven by the underlying forces of mantle convection and the upwelling of molten material from the Earth's mantle.
Divergent boundaries are commonly found along mid-ocean ridges, where new oceanic crust is formed. The process of seafloor spreading occurs as two tectonic plates move in opposite directions, creating a gap or rift between them. Magma from the underlying mantle rises to fill the gap, solidifies upon contact with the cold seawater, and forms new crust. This continuous upwelling and solidification of magma along the divergent boundary leads to the widening of the seafloor and the creation of new oceanic crust.
Hence , C is the correct option

What is the number in a chemical formula that tells the number of specific atoms in the molecule?
which statement best explains why muscle cells and skin cells do not look and act the same?
1.) The two types of cells have different genes
2.) There is no similarity in the chromosomes of the two types of cells
3.) All of the same genes are being expressed in both types of cells
4.) The genes in each type of cell are being expressed differently
Answer: Option 4 The genes in each type of cell are being expressed differently
Explanation:
Both skin cells and muscle cells are somatic cells i.e the cells that make up the body parts.Since, both of them are somatic cells they both contain the same number of chromosomes which in case of humans is 23 pairs.The set of genes present in each type of cell in the body is the same and therefore, both muscle cell and skin cells have the same genes.The reason why muscle cells and skin cells do not look and act the same is that even though these cells contain the same genes, there is differential expression of genes in these cells.Differential expression of genes basically means that different combination of genes are activated in a cell which plays a role of defining the purpose of the cell. This means that the set of genes that are activated in the skin cells are different from that of the muscle cells.As the genes are being expressed differently in the muscle and skin cells, both these cells acquire different characteristics and thus, look different and perform different functions.So out of all the options, option 4 is the correct one.
How is over-irrigation damaging to soil? a. It reduces the amount of organic material in soil. b. It results in the accumulation of salt near the soil surface. c. It increases the acidity of soil. d. It removes water from the water table. Please select the best answer from the choices provided A B C D
it is B.
It results in the accumulation of salt near the soil surface. hope this helps
Over irrigation is a mistake made by farmers which results in the accumulation of salt near the soil surface. Therefore, option (B) is correct.
What is over-irrigation?Farmers frequently overirrigate their fields, especially when soil moisture monitoring equipment is not being used.
Regular irrigation with too much water raises the groundwater level and produces more solvent salts. Salts from saline groundwater evaporate and condense on the soil's surface. Additionally, irrigation water becomes more salted as a result of canal water seepage.
Your soil's aeration and salinity are both impacted by excessive irrigation. It implies that your plants' roots will lose important nitrogen and absorb more salt. Your plants' and flowers' growth may be hampered by the fact that most plants dislike growing in saline soil.

If you stained both, onion cells and cheek cells what would stain the quickest and why?
Onion cells would stain quicker due to their thick cellulose wall that binds readily to stains, unlike the delicate plasma membrane of cheek cells.
Explanation:If you stain both, onion cells and cheek cells, the onion cells would stain quicker. This is largely due to the fact that onion cells have a thick and rigid cell wall made of cellulose, which readily binds to stains.
On the other hand, cheek cells are animal cells and have a thinner, more delicate plasma membrane, which can make staining more difficult and time-consuming.
This is especially evident when using a common biological stain like iodine. Iodine stains cellulose in the onion cell wall quickly, turning it a dark color that's easy to see under a microscope. In contrast, cheek cells, lacking cellulose walls, take longer to show reaction with the stain.
