Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 13.91 - 12 = 1.91 mL

We have

[tex]density = \frac{15}{1.91} \\ = 7.853403141...[/tex]

We have the final answer as

C 1 and 3

Explanation:

Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.

Crystals grow because salt molecules in the solution meet up and interlock. As they do so, they fit together like puzzle pieces, arranging themselves in a lattice structure, thus creating a crystal nucleus. ... it crystallizes.

Answer:

Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins. c Food provides the amino acids needed to make body proteins.

Answer:

A Mineral can be identified if they have the following properties:

1) Naturally occurring: it should be present in nature on its own, steel is not a   mineral because it is made manually.

2) Inorganic it should not be produced by any organism

3) Solid It should not be in liquid or gaseous state, water is not a mineral because its liquid.

4) Definite chemical composition it should have a limited variation in its chemical properties.

5) Ordered internal structure it should have definite internal repeating structure that does not varies much.

Answer:

9.28moles

Explanation:

Given parameters:

volume  = 11.1L

pressure  = 204atm

temperature  = 24°C = 24 + 273  = 297K

Unknown:

Number of moles of air in the cylinder  = ?

Solution:

To solve this problem, we apply the ideal gas equation;

         PV = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant  = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

Now insert the parameters and find n;

     204 x 11.1  = n x 0.082 x 297

    226.4  = 24.4n

        n  = 9.28moles

The number of moles of air in the cylinder is 92.98 moles

From the following parameters given, we are to determine the number of moles of air in the cylinder.

Given that:

The number of moles of air can be determined by using the relation for the ideal gas equation which can be expressed as:

where

Making (n) the subject of the formula:

[tex]\mathbf{n = \dfrac{PV}{RT}}[/tex]

[tex]\mathbf{n = \dfrac{204 \ atm \times 11.1 L}{0.082 \ L .atm/mol .K \times 297 \ K}}[/tex]

n = 92.98 moles

Answer:

No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

Answer:

Cl has 7 dots

if its Cl2; Cl-Cl it will contain 14 dots

Explanation:

The electron-dot formula of the chlorine molecule Cl₂is shown in the attached diagram below.

A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.

Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.

As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.

First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.

As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

Explanation:

BECAUSE DONT ASK

Answer:

Molecules in solids are tightly packed because the atoms are freezed together. Molecules in liquids are loosely packed because atoms are broken down and can move anywhere. Molecules in gases are free; the atoms can move or spread anywhere.

Solids do not move; hence no speed.

Liquids move and slide past past each other.

Gases move freely at high speeds

1)Oxygen atoms have 8 electrons and the shell structure is 2.6. The ground state electron configuration of ground state gaseous neutral oxygen is [He]. 2s2. 2p4 and the term symbol is 3P2.

Explanation:

2)If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state
