what process in the natural world converts radiant energy into chemical energy?

Answer:

Plate tetonics theory is the idea that different tectonic plates, are constantly moving and changing the surface of our Earth. They can move in three ways, convergent, divergent, and transform. Seafloor Spreading is like an example of divergent movement. When the plates diverge from each other it can create various changes such as creating a new sea floor. You can use seafloor spreading as an example of the plate tetonics theory.

Hydroxychloroquine cannot be made from grapefruit and lemon rinds.

Hydroxychloroquine is not a natural compound, rather it can only be synthesized from quinoline molecule in the laboratories.

During the synthesis of hydroxychloroquine, several sequential chemical reactions and purifications are done.

Hydroxychloroquine is used in the treatment of:

But when grapefruit and lemon rinds are boiled in water, a natural chemical compound known as limonene is obtained.

Therefore, hydroxychloroquine cannot be made from grapefruit and lemon rinds,

Answer: The condensation is the process which causes distance.

Answer:

The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.

Remember these followings :-

Acid + Base = salt + water

Acid + metal = salt + hydrogen

Acid + carbonates = salt + water + carbon dioxide

Base + ammonium salt = salt + ammonia + water

Base + acidic oxide = salt + water

I hope that you will be clear via these formulas.

The empirical formula of a compound that consists of 0.039 moles of iron atoms combined with 0.052 moles of oxygen atoms is FeO[tex]\rmFeO_{2}[/tex].

The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula are two straightforward examples of this idea.

The simplest whole number ratio of each type of atom in a compound is its empirical formula. It can be determined from data on the mass of each component in a compound or from the composition's proportion.

calculation:

Fe = 56/0.039 = 150

O = 16/0.052 = 300

in simplest term ratio is 1:2

Thus, empirical formula is FeO[tex]\rmFeO_{2}[/tex].

Answer:

pro ca help defeat diseases, con the stem cell might cause harm

Explanation:

The stem cells are used in regenerative medicine to reproduce the body organs and replace the damaged orangs. The disadvantage of stem cells is that it is difficult to culture the stem cells, and they can be transformed into cancerous cells.

Embryonic stem cells can be described as pluripotent stem cells derived from the inner cell mass of a blastocyst. Human embryos can reach the blastocyst stage 4 to 5 days post fertilization, at which time they contain 50 to 150 cells.

Isolating the inner cell mass using immunosurgery results in the destruction of the blastocyst, a process that raises ethical issues,  at the pre-implantation stage have the same moral considerations as embryos in the post-implantation stage of development.

Potential uses of stem cells include the treatment of diabetes and heart disease. The cells are being analyzed or studied to be used in clinical therapies, genetic disorders, and cellular/DNA repair. However, adverse effects in the research processes and clinical processes such as tumors and unwanted responses have been reported.

Considering the reaction stoichiometry, the quantity of moles of H₂O produced is 3.02 moles.

The balanced reaction is:

CuO + H₂ → Cu + H₂O

The molar mass of the compounds present in the reaction is:

Then, by reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of mass of each compound participate in the reaction:  

Then, it is possible to determine the moles of H₂O necessary by the following rule of three:  If by reaction stoichiometry 79.55 grams of CuO produces 1 mole of H₂O, 240 grams of CuO produces how many moles of H₂O?

[tex]molesofH_{2} O=\frac{240 grams of CuOx 1 mole ofH_{2} O }{79.55 grams of CuO}[/tex]

The part that contains the information that a plant cell uses for growth and activities is known as Chromosome. Thus, the correct option for this question is C.

Chromosomes may be defined as thread-like structures that appear during cell division. These structures are present in the nucleus of the cell and are made up of DNA, RNA, histones, and some non-histone proteins.

Chromosomes were first discovered by E. Strasburger in 1875. But the term chromosome was given by Waldeyer in 1888. Ultimately, the nucleus of the cell contains all sorts of genetic information which are essential for the growth and activities of organisms.

The Nucleus contains DNA which is known as the genetic material of most organisms including plants.

Therefore, a chromosome is a part that contains the information that a plant cell uses for growth and activities. Thus, the correct option for this question is C.

Conclusion:  

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.  

Using two to three sentences, summarize what you investigated and observed in this lab. I investigated how chemical compounds work and what to use to put them together.  

Why do you believe knowing how elements and compounds react together is essential in everyday matters? So, you can cook and stop injuries, these two things happen a lot in day-to-day life.  

Some elements are more "reactive" than other elements; why do you think this is? Because certain elements in the compound may react more to fire or water and many other elements.  

Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. Because if you add all the atoms, put in that’s the total amount. For example, water has one hydrogen atom and one oxygen atom, so water has two atoms.  

Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds, or do we have many compounds in this world? Yes, it is possible like water and hydrogen peroxide. The formula of water is H20 but hydrogen peroxide has one more oxygen-H202.

In Iron (II) oxide, ratio is 1:1

In iron (III) oxide, ratio is 4:2

[tex].[/tex]

In Iron (II) oxide, ratio is 1:1

Iron oxides are very important components in most soils as they have major influence on chemical, physical, and microbial properties of soils. Because of their nanoparticulate size (usually 5-200 nm), iron oxides possess large specific surface area.

Generally, iron oxides are prevalent, widely used as they are inexpensive, and play an imperative role in many biological and geological processes. They are also extensively used by humans, eg, as iron ores in thermite, catalysts, durable pigments.

When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide. The iron oxide typically has a reddish, flaky appearance that becomes progressively worse over time.
