Explanation:

I looked it up it's been answer 29 times same answer

Answer with Explanation:

The units used to express the densities of gases are different from those of solids and liquids because the particles in gas are widely separated from each other, unlike the particles in solid and liquid which are almost the same. The particles in solid are very close together. Considering it melts (if it's an ice), it will turn into a liquid and the change in volume is slightly greater only. However, if the liquid evaporates and transitions into a gas, the volume becomes largely different from its solid and liquid state. This is because the particles are much farther apart and free to move.

See answer below

Explanation:

As you are asking for chemical formula and ionic equation, then, I will assume that after the station #5 below, are the solutions you are requiring.

You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.

Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.

1. Solution 1 Barium Chloride:

In this case we have Barium on one side, and Chlorine on the other side, the symbol for those are Ba and Cl. As Barium have the +2 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Chlorine it will be -1, so, the formula will be:

BaCl₂

And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:

Ba²⁺ + 2Cl⁻ ------> BaCl₂

2. Solution 2 and 3, Copper (II) nitrate and Copper(II) sulfate:

In this case I will work with both, because both of the solution have copper and the only difference is the anion, which is nitrate in one, and sulfate on the other. In this cases, we have a tertiary salt, The copper's symbol is Cu, and is working with it oxydation state +2. Nitrate is an anion and have the formula NO₃ working with the oxydation state -1. Sulfate is SO₄ and works with oxydation state -2 instead.

The chemical formula and ionic equation for both will be:

Copper(II) nitrate: Cu(NO₃)₂

Copper(II) sulfate: CuSO₄

And the net equations:

Copper nitrate: Cu²⁺ + 2NO₃⁻ ------> Cu(NO₃)₂

Copper sulfate: Cu²⁺ + SO₄²⁻ -------> CuSO₄

Hope this helps

Answer:

d.

Explanation:

Answer:

Correct answer is A.

Explanation:

Frequency is the number of oscillations that a wave have per unit time. Since time is measured in seconds, the wave with the highest frequency must register the highest number of oscillation per second. Hence, correct answer is A.

Explanation:

Renatta Gass is out with her friends. Misfortune occurs and Renatta and her friends find themselves getting a workout. They apply a cumulative force of 1080 N to push the car 21,800 cm to the nearest fuel station. Determine the work done on the car.

Step 1: Given data

Step 2: Convert "d" to meters

We will use the conversion factor 1 m = 100 cm.

21,800 cm × 1 m/100 cm = 218 m

Step 3: Calculate the work done (W)

We will use the following expression.

W = F × d

W = 1080 N × 218 m = 2.35 × 10⁵ J

Answer:

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson.

Explanation:

Answer: He is modeling the condensation process in the water cycle.

An atom with one electron in its valence shell will tend to lose that electron to achieve the noble gas configuration and becomes a cation.

Cations are positively charged ions and are formed when an atom loses its electrons. They lose one or more electrons from their valence shell but do not lose any protons. Therefore, they get a net positive charge. Some examples of cations are  Potassium (K⁺), Calcium (Ca²⁺), and hydrogen (H⁺).

Anions and cations are both ions and have opposite electrical charges. They feel attraction for each other. A cation repels another cation whereas an anion repels another anion.

An atom that has one electron in its valence shell will always tend to lose that electron to get completely filled electronic configuration. So the atom will convert into a cation to attain the more stable noble gas configuration.

For example, sodium has an electronic configuration 1s²2s²2p⁶3s¹. It has one electron in its valence shell, so it converts into Na⁺ by losing one electron and attains a configuration similar to Neon noble gas.

The volume of O₂ : 21 L

Given

8.7 grams of C₂H₄

Required

Volume O₂

Solution

Reaction

C₂H₄ + 3 O₂ ⇒ 2 CO₂ + 2 H₂O

mol C₂H₄(MW= 28 g/mol) :

= mass : MW

= 8.7 g : 28 g/mol

= 0.311

From the equation, mol  O₂ :

= 3/1 x mol C₂H₄

= 3/1 x 0.311

= 0.933

At STP, 1 mol gas=22.4 L, so for 0.933 mol :

= 0.933 x 22.4 L

= 20.899 L ≈ 21 L

Explanation:

An element is a distinct substance that cannot be split-up into simpler substances. Such substances are only made up of one kind of atom.

A compound is composed of two or more kinds of atoms joined together in a definite  grouping.

A homogenous mixture is a mixture in which its constituents exists in just one phase.

A heterogeneous mixture is one whose constituents exists in at least two different phases.

S₈ is a compound

CH₄ is a compound

Salt water is a homogenous mixture

Distilled water is a compound
