We have that for the Question "" it can be said that the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is
Amount of CO_2(g)=221.35g
From the question we are told
What is the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules?
Generally the equation for the is mathematically given as
[tex]No moles in 3*02*10^{24}=\frac{3.03*10^{24}}{6.023*10^-{23}}[/tex]
No moles in 3*02*10^{24}=5.03moles
Amount of CO_2(g)=5.03moles *44g/mol
Amount of CO_2(g)=221.35g
Hence
the mass (in grams) of 3.03 × 1024 molecules of carbon dioxide molecules is
Amount of CO_2(g)=221.35g

In 2006, scientists decided that Pluto
had more in common with
than the original 8 planets of the solar
system.
A: the other, newly discovered, dwarf planets
b: the moon
c: the asteroids
Scientists decided that Pluto are more in common with than the original 8 planets of the solar system will be the other, newly discovered, dwarf planets. Option A is correct.
In 2006, scientists redefined the definition of a planet, leading to the reclassification of Pluto as a dwarf planet. This decision was influenced by the discovery of other celestial bodies in the outer regions of the solar system that shared similar characteristics with Pluto.
The other, newly discovered, dwarf planets" is correct. Scientists recognized that there were other objects in the solar system, such as Eris, Haumea, Makemake, and Ceres, that shared similar characteristics with Pluto and were classified as dwarf planets alongside Pluto.
This reclassification highlighted the presence of a population of objects in the outer regions of the solar system known as the Kuiper Belt, which consists of numerous icy bodies similar to Pluto. By considering the properties and characteristics of these newly discovered dwarf planets, scientists concluded that Pluto had more in common with these objects than with the original eight planets of the solar system.
The moon and the asteroids are not accurate. While the moon and asteroids are significant celestial objects in the solar system, they do not represent the specific group of objects that are considered dwarf planets and have characteristics similar to Pluto.
Hence, A. is the correct option.

If the hydrogen ion concentration of a solution is 10M, is the solution acidic, alkaline, or neutral? Group of answer choices alkaline neutral acidic The answer cannot be determined.
Answer:
1) If the hydrogen ion concentration of a solution is 10–10M, is the solution is definitely alkaline. The thing I used to determine that fact is basic point - pH above 7 is always alkaine, and as a proof we can see from the task that the concentration of hydroxyl OH- is pretty higher than hydrogen H+, which is a direct charachteristic of alkain solution.
Explanation:Here is a tip for you, I bet it will be useful :
>7 = basic
<7 = acidic
7 = neutral

Consider the sugar below. Which term best describes this sugar? disaccharide monosaccharide polysaccharide saccharide
oh wait i wrote whole paragraphs let me fix this
okay so you mean this ?
a term for disaccharides would be double sugar or boise!
monosaccharides are simple sugars soluble in water. any class of sugars like glucose.
polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.
saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)
n. 2. n
To solve this we must be knowing each and every concept related to monosaccharide, polysaccharide and disaccharide. Therefore, monosaccharide is the term which describes the given sugar.
What is sugar?Sugar is the generic term for a variety of sweet-tasting, soluble sugars, many of which are utilized in food. Glucose, galactose, and fructose are examples of simple sugars, often known as monosaccharides.
Disaccharides comprise sugars (carbohydrate compounds) created when two simple sugars, or monosaccharides, combine to create a disaccharide.
Polysaccharides, also known as polycarbohydrates, are among the most common carbohydrates present in foods. They are polymeric long-chain carbohydrates made up of monosaccharide units linked together by glycosidic bonds.
Therefore, monosaccharide is the term which describes the given sugar.

Mariah wants to determine how much energy is needed to change 500 g of liquid water at 100°C to steam at 100°C. What information will BEST help her make this
calculation?
During the chemical reaction given below 21.71 grams of each reagent were allowed to react. Determine how many grams of the excess reagent are left over after the reaction is complete. 2SO2()+O2()⟶2SO3()
Answer: 16.32 g of [tex]O_2[/tex] as excess reagent are left.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} SO_2=\frac{21.71g}{64g/mol}=0.34mol[/tex]
[tex]\text{Moles of} O_2=\frac{21.71g}{32g/mol}=0.68mol[/tex]
[tex]2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)[/tex]
According to stoichiometry :
2 moles of [tex]SO_2[/tex] require = 1 mole of [tex]O_2[/tex]
Thus 0.34 moles of [tex]SO_2[/tex] will require=[tex]\frac{1}{2}\times 0.34=0.17moles[/tex] of [tex]O_2[/tex]
Thus [tex]SO_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
Moles of [tex]O_2[/tex] left = (0.68-0.17) mol = 0.51 mol
Mass of [tex]O_2=moles\times {\text {Molar mass}}=0.51moles\times 32g/mol=16.32g[/tex]
Thus 16.32 g of [tex]O_2[/tex] as excess reagent are left.

How much stock solution is needed to make 250 mL of a 6.0 M solution. The stock solution has a molarity of 18 M.
Answer:
83 mL
Explanation:
Use the dilution equation M1V1 = M2V2
M1 = 18 M
V1 = ?
M2 = 6.0 M
M2 = 250 mL
Solve for V1 --> V1 = M2V2/M1
V1 = (6.0 M)(250 mL) / (18 M) = 83 mL
