How much electronic waste does Orlando produce ?

Answer:francium

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Explanation:

The least measure of the energy needed to remove the loosely bound electron of an atom or a molecule is called ionization energy.

The correct order from lowest to highest first ionization energy is:

This can be explained as:

Therefore, Cesium will have the least ionization energy as compared to sodium, aluminium and argon.

Answer:

(1) conversion of mass to energy

Explanation:

Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.

The primary result of a nuclear fission reaction is the conversion of energy to mass.

Hence, option 2 is the answer.

Explanation:

Answer:

Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust. (Basalts are a sima rocks.) Oceanic crust is dense, almost 3 grams per cubic centimeter (1.7 ounces per cubic inch).

Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other. As magma that wells up from these rifts in Earth’s surface cools, it becomes young oceanic crust. The age and density of oceanic crust increases with distance from mid-ocean ridges.

Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.

At convergent plate boundaries between continental and oceanic lithosphere, the dense oceanic lithosphere (including the crust) always subducts beneath the continental. In the northwestern United States, for example, the oceanic Juan de Fuca plate subducts beneath the continental North American plate. At convergent boundaries between two plates carrying oceanic lithosphere, the denser (usually the larger and deeper ocean basin) subducts. In the Japan Trench, the dense Pacific plate subducts beneath the less-dense Okhotsk plate.

Answer:

its turgor pressure decreases

Explanation: This is also important because this function regulates water loss within the plant. Lower turgor pressure can mean that the cell has a low water concentration and closing the stomata would help to preserve water. :-)

When a leaf loses much-needed water, its turgor pressure would decrease. Hence Option A is Correct

Turgor Pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.

When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.

Thus, the turgor pressure created by the presence of water is lost by the absence of water.

The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

Answer:

25 atoms

Explanation:

Given data:

Total number of atoms = 400 atom

Atoms remain after 4 half lives passed = ?

Solution:

At time zero = 400 atom

At first half life = 400 atom/2 = 200 atom

At 2nd half life = 200 atom/2 = 100 atom

At 3rd half life = 100 atom/2 = 50 atom

At 4th half life = 50 atom/2 = 25 atom

Thus, 25 atoms are remained after 4 half lives.

25 atoms of the radioactive atoms will remain after 4 half lives.

    Given in the question,

Expression for the amount remaining of a radioactive element after 'n' half lives is given by,

[tex]N=N_0(\frac{1}{2})^n[/tex]

Here, [tex]N_0=[/tex] Initial amount

[tex]n=[/tex] Number of half lives

By substituting the vales of [tex]N_0[/tex] and [tex]n[/tex] in the question,

[tex]N=400(\frac{1}{2})^4[/tex]

   [tex]=\frac{400}{16}[/tex]

Answer:

C

Explanation:

Just look at the reactants.

2AgCl + BaBr2

The first reactant is made of 2 elements.

The second reactant is made of 2 elements.

It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like

2MgO ===> 2Mg + O2

is a decomposition.  One compound breaking down into 2 elements Mg and O.

It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like

C3H8 + 5O2 ==> 3CO2 + 4H2O

That would be what a combustion looks like

It can't be a single replacement. They look like

Mg + CuO ===> Cu + MgO

There are elements on both sides of the reaction.

Explanation:

Answer:

[tex]\boxed {\boxed {\sf FeBr_3}}[/tex]

Explanation:

We can assume that this is a neutral compound, meaning the charges of the ions are balanced.

We are given: Iron (III) Bromide.

We want to find the chemical formula.

First, find the symbols of the elements.

Next, find the charges on the ions.

The Roman Numeral 3 in parentheses (III). This indicates the iron cation has a charge of +3.

We need to balance out the charge of +3 with the bromine. Bromine can have a charge of +5, +1, and -1. Since we already have a cation (positive ion), bromine must be an anion (negative ion). We also know the charge must be negative to balance out the compound.

But, the charge is only -1. That would still leave the compound unbalanced. Therefore, we must have 3 bromine atoms to balance out the iron. The 3 will become a subscript.

So, put all the information together and write the formula:

FeBr₃

A chemical formula lists the constituent elements of a compound together with the number of atoms in each element's smallest unit, such as a molecule or formula unit. Here the formula for Iron (III) Bromate is FeBr₃.

A compound's chemical composition is symbolically represented by its chemical formula. Chemical formulas reveal the elements that make up a compound's molecules as well as the ratio in which their atoms combine to create those molecules.

The sorts of atoms and their numbers in an element or compound are described by a chemical formula. Each element's atoms are denoted by one or two distinct letters. a collection of chemical symbols indicating the constituent elements and their corresponding ratios.
