Answer:

yes, the amount doesn’t change, only the mass changes

Answer: Is this a true or false question? if it is I believe the answer is True

Explanation:

This is a true statement. Objects with more mass have a larger gravitational force, and stars have many, many times more mass than planets.

Answer:

Carbon pool

Earth's carbon pools.

The ocean (~37,000 GtC).

Terrestrial ecosystems (~3,000 GtC).

Earth's crust (sedimentary rocks ~75,000,000 GtC).

The atmosphere (~830 GtC).

Answer:

One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.

The number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms

From the question,

We are to determine the number of atoms present in 1.5 moles of iron.

From the formula,

[tex]Number\ of\ moles = \frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]

Then, we can write that

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of iron present = 1.5 × 6.022×10²³

Number of atoms of iron present = 9.033 ×10²³ atoms

Number of atoms of iron present ≅ 9.0 ×10²³ atoms

Hence, the number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms

Answer:

D

Explanation:

Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.

Starch is classified as a option  D. polysaccharide. Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units, which are simple sugar molecules.

Starch is a type of carbohydrate that is made up of many smaller sugar molecules.

It is made up of many smaller sugar units called glucose molecules that are attached together. Starch is a way for plants to store energy. It can be found in seeds, tubers, and other parts of plants. It is an important part of what we eat, especially in foods like potatoes, rice, and grains.

Hence option d is correct.

1 km per 10 minutes

Explanation:

Based on the map that's my conclusion

Answer:

It's actually 6 km/h and for b) it's 10 minutes

Explanation:

At 30 minutes the distance was 3km, so you multiply it by 2 to get 6km.

And then it's 10 minutes for part B)

Answer:

N₂   + 3H₂  →  2NH₃

Explanation:

To obey the law of conservation of mass, the number of atoms on both sides of the expression, must be the same.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

To express this in chemical reaction, the number of atoms must be the same in going from reactants to products.

                      N₂   + 3H₂  →  2NH₃

We have 2 atoms of Nitrogen on both sides of the expression.

Also, we have 6 atoms of hydrogen on both sides.

Answer:

Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.
