To determine the most similar element identify the atomic number of the element and other properties such as state of the matter, color, conductivity, or boiling point.

In the period table, elements are arranged based on two main factors:

Now, if you know both the atomic number or the properties you can determine which element is the most similar to the element that you have.

Explanation:

Though both the molecules contain carbon and oxygen, the general difference between them lies in their number of oxygen of atoms carried by them; as carbon dioxide (CO2) has one carbon atom and two oxygen atoms, while carbon monoxide (CO) has one carbon and one oxygen atom.

Carbon Dioxide is naturally present in our atmosphere and as it is excreted out during the process breathing by the animals and humans. On the other hand, Carbon Monoxide is toxic, and it produces suffocation if it builds while incomplete combustion of coal, fossil fuels, etc.

In the layman language, both the terms are sometimes used interchangeably and create confusion. As they have few similarities and incorporates carbon and oxygen as well, and are the byproducts of the things which carry carbon like fuels, coals, woods, and natural gas.

We all are aware of the three states of matter, which are Solid, Liquid and Gas. In this context, we will be discussing the two most common gases present in our atmosphere, how they vary from each other, their effects and their similarities. These gases are Carbon Dioxide and Carbon Monoxide.

Answer:

The major similarities between molecules of carbon monoxide, diatomic oxygen and carbon dioxide is that they all exist in gaseous states in their natural forms. Each of them also have low molecular weight of less than 70g/mol.

The difference between them is that the carbon monoxide is formed from incomplete combustion and is a toxic gas while carbon dioxide is an end product of respiration and is used by plants for photosynthesis. Oxygen on the other hand is essential for respiration and is the end product of photosynthesis.

Carbon dioxide and Carbon monoxide look most alike as they have the same elements which include Carbon and Oxygen but only different in the number of atom composition

The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s

2

It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.

Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s

2

will lose the two 7s electrons to form the cation with +2 charge.

Answer:

German chemist G.E. Stahl

Explanation:

this theory was first articulated in 1697

G. E. Stahl in 1697 is the scientist who is  credited with early, quantitative data on redox reactions.

The Redox reactions comprise of two parts a reduced part and an oxidized part, which occur simultaneously . The part which is reduced gain electrons and hence there is a increase in oxidation state of the species.

While, the part which is oxidized looses electrons and hence there is a decrease in oxidation state of the species.During redox reactions, there is no net change in the number of electrons . Electrons which are given off in oxidation are used up in reduction.

The ion or molecule which accepts electrons is called as oxidizing agent while the ion or molecule which donates electrons is called as a reducing agent.

Answer:

Alkali metals are highly reactive metals. These metals are that much reactive that they can even explode in the air as well. When alkali metals and water react with each other, there is a formation of metal hydroxide and the evolution of hydrogen gas.

The general representation of metal is A. so, the general equation for the reaction of an alkali metal with water is given below.

2A(solid)+2H2O(liquid) -------> 2AOH(aqeous)+H2(gas)

The term “alchemy” brings to mind a cauldron-full of images: witches hovering over a boiling brew, or maybe sorcerers in smoky labs or untidy libraries. Despite these connotations of the mythic and mystical, alchemical follow contend a crucial role within the evolution of contemporary science.

Historically, alchemy refers to each the investigation of nature and an early philosophical and religious discipline that combined chemistry with metal work. Alchemy additionally encompassed physics, medicine, astrology, mysticism, spiritualism, and art.

Alchemy was scientific however it absolutely was additionally a religious tradition. a number of its practitioners had selfless intentions. for example, if alchemists might learn the key of “purifying” base metals into gold, they could gain the flexibility to purify the human soul. At an equivalent time, alchemy has typically been seen as a get-rich-quick theme and plenty of alchemists as charlatans and pretenders. however several alchemists were really serious-minded practitioners whose work helped lay the groundwork for contemporary chemistry and medication.

Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.

Answer:

maybe 25 joules

Explanation:

please mark me as a brainlist

If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.

Energy is referred to by scientists as the capacity for work. People have figured out how to transform energy from one form to another and then use it to accomplish tasks, making modern civilization possible.

Walking and bicycling, driving cars on roads and boats through water, cooking meals on stoves, making ice in freezers, lighting our homes and workplaces, producing goods, and sending astronauts into space all require the usage of energy.

Energy is capable of changing its forms. For instance, a person's body stores chemical energy from the food they consume until they may use it as kinetic energy when working or playing.

Therefore, If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.
