A perfect cube of aluminum metal was found to weigh 20.00 g. The density of aluminum is 2.7 g/ml. What are the dimensions of the
denis23 [38]

Answer:

             Height  = 1.9493 cm

             Width =  1.9493 cm

             Depth  =  1.9493 cm

Solution:

Data Given:

                  Mass  =  20 g

                  Density  =  2.7 g/mL

Step 1: Calculate the Volume,

As,

                                        Density  =  Mass ÷ Volume

Or,

                                        Volume  =  Mass ÷ Density

Putting values,

                                        Volume  =  20 g ÷ 2.7 g/mL

                                        Volume  =  7.407 mL or 7.407 cm³

Step 2: Calculate Dimensions of the Cube:

As we know,

                                        Volume  =  length × width × depth

So, we will take the cube root of 7.407 cm³ which is 1.9493 cm.

Hence,

                                        Volume  =  1.9493 cm × 1.9493 cm × 1.9493 cm

                                        Volume  =  7.407 cm³

Western regions Facts
babunello [35]
This region has both the state with the smallest population (Wyoming) and the largest population (California).
Alaska's land area is much bigger than any other state, but it has one of the lowest populations.
The western US takes up about half of the land of the United States.

The western United States is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier.


Hope this helps :)

Have a great day!

A combustion reaction occurs between one molecule of methane (CHa) and two molecules of oxygen (O2).
SCORPION-xisa [38]

The total number of atoms make up the products :

D) 1 carbon, 4 hydrogen, and 4 oxygen

<h3>Further explanation </h3>

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O

Hydrocarbon combustion reactions (especially alkanes)

For combustion of methane (CH₄) and two molecules of oxygen (O₂).

\tt CH_4+2O_2\rightarrow CO_2+2H_2O

The number of atoms make up the products

CO₂ : 1 carbon, 2 oxygen

2H₂O : 4 hydrogen , 2 oxygen

State the type of bonding—ionic, covalent, or metallic—you would expect in each:<br> (b) MgCl₂(s);
IceJOKER [234]

MgCl2 is an ionic compound because chemical bonds in the molecule are formed by the transfer of electrons among Mg and Cl atoms.

<h3>What is chemical bond ?</h3>

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."

The positively charged protons in the nucleus and the negatively charged electrons in its orbit are attracted to one another by the basic electromagnetic force.
