Describe how glacier mice are complete ecosystems, even though they are tiny.
GIVING BRAINIEST

Answers

Answer: The clumps, known as glacier mice, have been found to contain miniature ecosystems

Explanation: Because glaciers are in constant, if slow, motion and are frequently blasted by strong winds.

The clumps, known as glacier mice, have been found to contain miniature ecosystems. And even in freezing temperatures, scientists found, the inhabitants manage to thrive. In high winds glacier mice, which form when clumps of dust and organic debris develop a layer of moss over time, hop across vast sheets of ice.

What organisms live in glacier mice?

These included springtails (small insect-like animals), water bears (also known as tardigrades, the only animals known to have survived in space), and roundworms. Globally, glacier mice are rare.

Answers

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.

which scientist is credited with early, quantitative data on redox reactions?

Answers

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.

What are 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.

. Describe the differences and similarities between the molecules of carbon monoxide, diatomic oxygen and carbon dioxide. Which two appear most alike?

Answers

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

Answers

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:

Their atomic number or the number of protons: This means the first element has the lowest atomic number (1) and the last element Ogannesson has the highest atomic number (118).Their properties such as conductivity, boiling point, among others: Elements are organized in sub-groups such as metals, halogens, etc. based on their elements.

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.

Note: This question is incomplete because there is no information bout the element "oregano"; due to this, I answered it based on general knowledge.

My sprinkler reaches from 0 feet to 16 feet away from the sprinkler. The data are given in Table 1. The sprinkler distributes water in a circular pattern, so I assumed that points the same distance from the sprinkler received the same amounts of water. One way to use the data in Table 1 to estimate how many cubic feet of water my lawn got from my sprinkler in one hour is to write down an integral for the volume of water using the method of shells, and then use a right-endpoint Riemann sum to approximate this integral.
