what did the law of octaves state about the elements​

Answers

Law of octaves states that when the elements are arranged in ascending order of atomic mass, every eighth element has comparable properties.

What are the characteristics of law of octaves ?

Features of law of octaves -:

Newland Octaves arranged the known 62 elements into 8 groups of 8 each. The elements were in increasing order of atomic weight.Every element shared properties with the 8th element after it.

Some limitations were made into this -:

It left no space for new elements to be discovered. It grouped some dissimilar elements together, e.g. halogens with metals. It worked well only up to Calcium.

The law of octaves state about the elements​ that there must be 8 electrons in the outermost or valance shell of the electron to obtained the stability.

What is octaves rule?

when the elements are arranged in the increasing order of atomic mass, every eighth element has comparable properties and  that  was the first time an atomic number was introduced  to each element of the periodic table.

To become the stable according to rule element must complete it octave otherwise it cannot be considered the stable one.

7. (50 points) If you have 25 grams of Aluminum (Al), how many moles of hydrogen
gas (H) can you make? Show work!

Answers

Hello,

I believe this is (25 g Al) * (1 mol H / 1.008 g H) = 24.8015 mol H

Hopefully that was the right approach.
I thought that if one mole of Al is
26.982 g, then the numbers of moles for H (1.008 g/mol) would be about 25 mol.
If it doesn’t make sense or if you have resources/notes to which I can refer, I’ll see what I can do!

3. How many atoms of oxygen are present in 50g of Fe(H20)2(S04)3? Please answer fast

Answers

Answer:

1. 7.227x10²⁴ O atoms

2. 0.1944 mol

3. 3.18x10²³ atoms

Explanation:

1. To solve this problem we need to use Avogadro's number, which states the number of molecules that are in 1 mol of a substance:

0.04 mol NaNO₃ * 6.023x10²³ molecules/mol = 2.409x10²⁴ molecules NaNO₃

There are 3 O atoms per NaNO₃ molecule, thus the answer is (3* 2.409x10²⁴) 7.227x10²⁴ atoms.

2. First we convert 10.5 g of N₂O₅ into moles, using its molar mass:

10.5 g N₂O₅ ÷ 108 g/mol = 0.0972 mol N₂O₅

There are 2 N moles per N₂O₅ mol, thus the answer is (2*0.0972) 0.1944 mol.

3. First we convert grams into moles:

50 g Fe(H₂O)₂(SO₄)₃ ÷ 379.85 g/mol = 0.132 mol

Then we use Avogadro's number:

0.132 mol * 6.023x10²³ molecules/mol = 7.95x10²² molecules Fe(H₂O)₂(SO₄)₃

There are 14 O atoms per Fe(H₂O)₂(SO₄)₃ molecule, so the answer is (7.95x10²² * 4) 3.18x10²³ atoms.

will mark brainlest 1) Now that you have studied the facts about the Severn River, you are ready to make a decision. What questions would you want answered if you were to determine whether to build a tidal power plant at the Severn River?

Answers

Answer:

The questions I would like to answer are:

Will the productivity of the river severn offset the cost of installing the plant?

Is it possible to build a dam on site?

Is it possible to establish submerged turbines in this location?

How would human life and nature be impacted by the plant?

Explanation:

Tidal power plants are signals that use tidal energy to generate electricity. The installation of this type of plant is quite expensive and involves the establishment of dams on site to take advantage of the differences between high and low tides and the establishment of submerged turbines to take advantage of sea currents.

To decide whether I would decide to build a tidal plant on the Severn River, I would need to evaluate a few things to make sure that the project is viable. For that I would ask myself some questions like:

Will the productivity of the river severn offset the cost of installing the plant? (If the installation costs are greater than the capacity of this river to promote high generation of electricity, it would be better to abandon the project)

Is it possible to build a dam on site? Is it possible to establish submerged turbines in this location? (It is necessary to consider the physical and chemical characteristics of the place to know if it is possible to install these two equipment and in a way that they work efficiently)

How would human life and nature be impacted by the plant? (Projects like this include major environmental and social impacts. These impacts must be analyzed and ways to mitigate them must be considered and included in the project.)
