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

Redshift is observed when:(1 point)
A. a luminous object is stationary relative to an observer.
B. a luminous object is traveling alongside an observer.
C. a distant luminous object travels rapidly towards an observer.
D. a distant luminous object travels rapidly away from an observer.
Answer:it’s C
Explanation:
A distant luminous object travels rapidly away from an observer.
Redshift is observed when a distant luminous object travels rapidly towards an observer. Thus option C is correct.
What is luminous object?Luminous object is defined as the sun is an example of a luminous object, whereas a non-luminous object is one that cannot create light.
It is also defined as objects that can generate their own light energy.
Non luminous object is defined as one that does not generate its own light but can reflect light from other sources.
It can also defined as object which do not generate their own light.
Redshift is defined as when the wavelength of the light is extended, it seems to be shifted towards the red section of the spectrum.
Thus, redshift is observed when a distant luminous object travels rapidly towards an observer. Thus option C is correct.

classical,alchemical,medical and technological traditions were chemistry forerunners. identify the contributions which of these made to the development of chemistry
Answer:
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.

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

How much heat is needed to raise the temperature of 100g of an iron from 25°C to
110°C?
(The specific heat of iron is 0.45 J/g∙°C).
Answer:
382.5J
Explanation:
Use the formula:
E = mcΔθ or Q = mcΔT
m = 100g
c = 0.45 J/g°C
ΔT or Δθ = 110 - 25 = 85°
Sub in the values:
E = 100 × 0.45 × 85
= 382.5J
