Answer: 15.99 x2g

Explanation:

The empirical formula of the compound (calcium bromide) is CaBr₂

From the question given above, the following data were obtained:

Ca = 4.02 g

Br = 15.95 g

Divide by their molar mass to obtain their mole

Ca = 4.02 / 40 = 0.1005 mole

Br = 15.95 / 80 = 0.199 mole

Divide by the smallest to obtain the mole ratio

Ca = 0.1005 / 0.1005 = 1

Br = 0.199 / 0.1005 = 2

Therefore, the empirical formula of calcium bromide is CaBr₂

Answer:

The situation given here is imaginary such that the life of Rock has to be found using the half-life of the element lokium that has been found inside the rock.

Half-life of any material is the amount of time taken by that particular material to decay. Now the amount of lokium found in rock can show after how many half-lives this amount has been left out.

The time elapsed will be log (L) atoms X half-life.

J.J. Thomson's experiments with cathode-ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. I would describe the structure of an atom as the plum pudding model.

Answer:

But when there is too much phosphorus and nitrogen into water systems, it can speed up the process of eutrophication ( increase in the concentration of minerals and nutrients, which enhances the growth of algae, which causes algal blooms). Due to this, dissolved oxygen level is declined as not enough light penetrates in the water body.

Corey made his solar oven by lining the inside of a shoe box with black paper, placing a piece of plastic wrap over the bottom of the shoe box, and lining the lid of the box with aluminum foil. He used a pencil to prop the lid open at an angle. The food will go on the black paper under the plastic wrap. The image shows Corey's shoe box oven.

Janelle's and Corey's designs both use aluminum foil, black paper, and either a plastic bag or plastic wrap so that means that they both absorb and they will retain and is u ever do it do not put it under a shave

The cart accelerated at a constant rate of approximately 0.8 m/s². Option (B) is correct.

Option B is the best description based on the graphed position data during the 7-second time interval. The cart's acceleration can be determined by analyzing the shape of the position-time graph.

If the cart was stationary, the position-time graph would be a horizontal line (option C). If the cart moved at a constant velocity, the graph would be a straight line inclined at a constant angle (option D).

However, the graph likely shows a curved line, indicating changing position over time. This suggests that the cart experienced acceleration. To further confirm, calculate the acceleration:

Acceleration (a) = Δv / Δt,

where Δv is the change in velocity and Δt is the change in time.

Given the time interval is 7 seconds, and the initial and final velocities are likely different, you can calculate the average acceleration. If the average acceleration is approximately 0.8 m/s², then option B is correct.

The graphed data aligns with the scenario of constant acceleration, supporting option B.

All the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Thus, all the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

Explanation:

DCO2/H2 = 44/2 = 22............................

Answer:

In today's world, the periodic table is very valuable for both students and scientists since it allows them to forecast the sorts of chemical reactions in which a specific element is likely to engage. Rather than memorizing facts and figures for each element, students and scientists can learn a great deal by simply looking at the table. They can learn about an element's reactivity, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics by simply looking at the table.

Groups are made up of elements that are in the same column as one another and have attributes that are comparable to one another. If we look at the first column (the alkali metals), for example, we see that they are all metals that have a 1+ charge in reactions, react quickly with water and combine easily with nonmetals.

Periods are made up of elements that are arranged in a row next to one another and have the same maximum unexcited electron energy level as one another.

The periodic table also has the advantage of providing all the information you need to balance chemical processes at a glance, which is a very valuable feature. The atomic number and, in most cases, the atomic weight of each element are included in the table. The group of an element indicates the characteristic charge of that element.
