True or false, The four units that must always be used when using the ideal gas are 44.0 liters

Answer: Crystal habit and cleavage.

Explanation:

When two physical properties of minerals both bring about smooth, flat surfaces that has specific angles between them.such that the first property is externally visible and is the result of how the mineral forms while the second property is internal and is the result of breaking a sample of the mineral, it should be noted that the properties are refered to as the crystal habit and cleavage.

It should be noted that the cleavage refers to the tendency of crystalline materials to be able to split along the structural planes.

Answer:

Simple squamous epithelium

This type of epithelia lines the inner surface of all blood vessels (endothelium), forms the wall of alveolar sacs in the lung and lines the body cavities (mesothelium). The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.

Answer:

D.[Ne] 3S2 3P2

Explanation:

The electron configuration for silicon is  [Ne] 3s² 3p². Hence Option (C) is correct.

Electronic configuration, also called electronic structure or electron configuration, the arrangement of electrons in orbitals around an atomic nucleus.

The electron configuration of an element describes how electrons are distributed in its atomic orbitals.

Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.

Silicon belongs to group 14th and 3rd period.Therefore, The electron configuration for silicon is  [Ne] 3s² 3p². Hence Option (C) is correct.

In this reaction, nitrogen acts as the oxidizing agent. Mg is a reducing agent.

Answer:

Energy is absorbed, so the mass is increased. Energy is released, so the mass is increased

Answer:

Below!

Explanation:

Lithium (Li) is more reactive than Beryllium (Be). This is because Lithium lacks the valence electron that Beryllium has. Elements with a lower amount of valence electrons are less stable than those with full valence shells, causing it to react more easily. Because Lithium only contains 1 valence electron, it is easily transferred/given up to create bonds and form compounds.

Hope this helps ya! Best of luck <3

Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Reactivity in chemistry is a gauge of the ease with which a substance reacts chemically. The chemical may react independently or in combination with other atoms and compounds, and in either case, energy will typically be released. The most reactive substances and elements have the potential to spontaneously or explosively ignite.

They typically ignite when exposed to oxygen in the atmosphere and water. Reactivity is temperature-dependent. The available energy for just a chemical reaction increases with temperature, often increasing its likelihood. The noble gases are the least reactive elements. Hydrogen is the least active catalyst in this group and doesn't produce any stable compounds. Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Therefore, compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

a compound is a pure substance made up of two or more elements chemically combined a molecule is defined as the smallest particle of an element which can exist separately elements are pure substances which can not be split into simple substances by chemical means the atom is defined as the smallest particle of an element which can take part in a chemical change so I think the difference between the molecule of a compound is bigger than the molecule of a compound

A measurement is the action of measuring something, or some amount of stuff. So it is important to measure certain things right, distance, time, and accuracy are all great things to measure. By measuring these things or in other words, by taking these measurements we can better understand the world around us.

Answer:

Measurement is the process of comparison of an unknown physical quantity with a known physical quantity.

It is important because measurement is needed in every day life we need measurement in simply cooking food to designing a house and many more other works.

Answer:

+3

Explanation:

The name of this compound would be nickel (III) oxide. Oxygen typically has a charge of -2. Given there are 3 oxygen atoms, that would equal a charge of -6. The nickel is the cation and must equal the charge of the anion, so must have a charge of +6. Since there are 2 nickel atoms, the charge on each must be +3.

[tex]{ \underline{ \sf{O _{2} \: is \: reduced}}}[/tex]

Explanation:

Reduction means when a reactant loses oxygen or gains hydrogen.

In the equation:

Hydrogen molecule, it neither gains nor loses hydrogen, but it gains oxygen. so :

[tex]{ \sf{H _{2} \: is \: excluded}}[/tex]

Oxygen molecule loses one oxygen atom, and gains four hydrogen atoms, hence it is reduced.

Answer:

KI

Explanation:

From the question, we can see that a qualitative analysis of the compound shows that it has a lilac flame colour. The lilac flame colour corresponds to the potassium ion (K^+).

Again, the test of addition of HNO3(aq) and AgNO3(aq) to a solution is a test for halogens. If the result is a green precipitate, then the ion present is the iodide ion (I^-).

Hence, the compound must be KI.
