Explanation:

What volume of O2 would be required to react with 4.6 grams of Na

Answers

Volume of O₂ = 1.12 L

Further explanation

The reaction equation is the chemical formula of reagents and product substances  

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products  

Reaction

4Na+O₂ ⇒ 2Na₂O

Ar Na = 23 g/mol

mol Na :

[tex]\tt mol=\dfrac{4.6}{23}=0.2[/tex]

mol O₂ :

[tex]\tt \dfrac{1}{4}\times 0.2=0.05[/tex]

Assume at STP (0 C, 1 atm), 22.4 L for 1 mol , then volume of O₂ :

2. What type of bonding would be expected between the following atoms?
a. Li and F
c. I and Br
b. Cu and S
d. S and O

Answers

a.) covalent
c.) covalent
b.) ionic
d.) covalent

Considering the definition of covalent and ionic bond, the type of bonding that would be expected between the following atoms is:

Li and F: Ionic Bond I and Br: Covalent Bond Cu and S: Ionic Bond S and O: Covalent Bond

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.  

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Taking into account the previous definitions, it is first necessary to know if the elements are metallic or non-metallic:

Lithium Li: Metallic atoms Flour F: Non-metallic atoms Iodine I: Non-metallic atomsBromine Br: Non-metallic atomsCopper Cu: Metallic atoms Sulfur S: Non-metallic atoms Oxygen O: Non-metallic atoms

Now you can determine the type of bond of the following pairs of elements:

Li and F: Metallic atoms - Non-metallic atoms: Ionic Bond I and Br: Non-metallic atoms - Non-metallic atoms: Covalent Bond Cu and S: Metallic atoms - Non-metallic atoms: Ionic Bond S and O: Non-metallic atoms - Non-metallic atoms: Covalent Bond

You crumple a piece of paper in your hands. Not all of the kinetic energy from your hands is used to crumple the paper. Where does the rest of the energy go?
A. It is transformed into sound energy.
B. It is transformed into light energy.
C. It is transformed into electrical energy. D. It is transformed into magnetic energy.​

Answers

Answer:

A

Explanation:

When you crumble a piece of paper it make a sound plus i just did on apex

When we crumple a piece of paper in our hands, a part of the energy is transformed into sound energy. Therefore, option (A) is correct.

What is sound energy?

Sound transmits through the medium such as liquids, gases, and plasma in the form of longitudinal waves or compression waves. It requires a medium to propagate as it can travel through solids as both longitudinal and transverse waves.

Transverse sound waves exhibit waves of alternating shear stress perpendicular to the direction of propagation while Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction.

Generally, waves move matter up and down but do not carry along.  When we crumple the paper with our hands the kinetic energy of our hands is used to deform the paper but at the same time, we can listen to some sound which indicates that some energy is transformed into sound energy.

Why is it important for you to know the properties and chemical formulas of molecular and ionic compounds? How will this affect your ability to choose one product over another or make decisions about whether to use a certain substance like bleach or drain cleaner? How has learning about atomic structure and compounds changed your understanding of the world around you?

Answers

Answer:

See explanation

Explanation:

It is important to know the properties and chemical formulas of ionic and molecular compounds because, knowledge of the properties of a compound aids you in deciding how to use the compound, how to store it and how dangerous it can be. Knowledge of its formula is the first step towards identifying its properties since most chemicals occur in groups having similar chemical/physical properties.

Knowledge of the chemical properties and formula of bleach and drain cleaner will help you to decide which product is a better cleaning agent based on its chemical composition. This will help you as the user to make  better decision.

Most metals are NOT ____ ? Liquid at room temperature, ductile, malleable, good conductors of heat and electricity.

Answers

Liquid at room temperature

Most metals are not liquid at room temperature. Therefore, option A is correct.

Most metals are not liquid at room temperature, except for a few specific exceptions such as mercury (Hg) and gallium (Ga). These metals have relatively low melting points, which allows them to exist in a liquid state at or near room temperature.

The majority of metals, however, exhibit a solid state at room temperature. This solid state is characterized by a regular arrangement of atoms or ions in a crystal lattice structure. The strength of metallic bonds holds the atoms together, giving metals their solid and rigid form.

why is diamond hard​

Answers

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

Answer: Diamond is hard due to its giant covalent lattice and it has many strong covalent bonds.
