This problem is providing the ionic radius of an anion, A²⁻ as 0.290 nm and asks for that of the cation A²⁺ in comparison to the former.

Firstly, we need to recall the concept of ionic radius, as the distance between the nucleus and the outermost electron shell of an ion. In such a way, we can have two scenarios:

1. Anions result from the gain of electrons exhibited by a nonmetal, which means they turn out bigger than the neutral atom.

2. Cations result from the loss of electrons exhibited by a metal, which means they turn out smaller than the neutral atom.

With the aforementioned, we infer that the cation A²⁺, will me smaller than the anion A²⁻, which means it will have an ionic radius smaller than 0.290 nm.

1. Water carving out a limestone cave

2. Oxidation

3. Acid rain

(Got 100%)

Explanation:

The primary agents of chemical weathering are water, oxygen and acids. So acid rain is an agent of chemical weathering. Option C is correct.

Water, and many chemical compounds found in water, is the main agent of chemical weathering.  One of the most abundant rock-forming minerals, chemically reacts with water and water-soluble compounds to form clay.

Water contains many weak acids such as carbonic acid. The primary agents of chemical weathering are water, oxygen and acids.

These react with surface rocks to form new minerals that are stable in, or in equilibrium with, the physical and chemical conditions present at the earth's surface.

Hence, option C is correct.

B. The ballon will repel the paper

Answer:

that is impossible. the atomic number can only go up each group

Answer:

B

Explanation:

new oceanic crust will form.

The formation of a new oceanic crust will be the primary result of the continuation of the geologic processes. Therefore, option (B) is correct.

The oceanic crust can be described as the uppermost layer of the oceanic portion of the tectonic plates. The oceanic crust is composed of the upper oceanic crust, with pillow lavas complex, and the lower oceanic crust, made of troctolite, and ultramafic cumulates.

The oceanic crust lies above the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together compose the oceanic lithosphere.

The oceanic crust is rich in iron and magnesium and composed of mafic rocks. It is thinner than the continental crust less than 10 Km thick but it is denser with 3.0 g/cm³ as opposed to the continental crust.

The oceanic crust displays a symmetrical pattern of positive and negative magnetic lines emanating from the mid-ocean ridge.

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.

Explanation:

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.

Bohr model A

Explanation:

It has more valance electrons therefore has more interaction between the atoms and has more electronegativity.

Answer:

D. Na has a larger radius than Na+ because Na+ has lost its outermost energy shell.

Explanation:

The radius is larger because the diameter of Na+ is larger.

Sodium has smaller atomic  radius than sodium cation because sodium has expanded electron cloud.

Atomic radius is defined as the  distance between outermost shell and the nucleus. Atomic radius varies across the periodic table where in groups it increases due to the fact that new shells are added on moving sown the group.

While in a period it decreases from left to right across the periodic table as electrons are added to the same shell which causes contraction of the atom.In case of comparison between an atom and a cation an atom has smaller atomic radius due to presence of electrons while in case of ions atomic radius is smaller as they have less number of electrons.

Atoms have expanded electron cloud while the electron cloud in case ions is small , the reason being the presence of large number of electrons in case of atoms and less number of electrons in case of ions.

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
