Find the element. Plz help!

Answer:

Explanation:

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

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

From the question

mass of metal = 10.5 g

volume = 13 cm³

We have

[tex]density = \frac{10.5}{13} \\ = 0.8076923...[/tex]

We have the final answer as

Hope this helps you

Answer:

0.807

Explanation:

mass/volume = density

10.5/13 = 0.807

Answer:

no it's part of chemistry to play thing exploring OR not.

Explanation:

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

Answer:

0.690666... g/cm^3

Explanation:

density=mass/volume. mass is 2.331 g and using the length we can determine that the volume of the cube is 3.375 cm^3. 2.331/3.375= 0.6906666....

Answer:

B When the molecule contains polar bonds.

Explanation:

AP-EXpert

The shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

The polarization of a molecule greatly depends on the shape of the molecule. The net dipole moment occurs only due to the uneven distribution of electrons between the two atoms.

So we can conclude that the shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

Answer:

0.032 lbs

Explanation:

Divide the mass value by 454.

Answer:

FALSE

Explanation:

Answer:

8.75×10¹³ mg

Explanation:

From the question given above, we obtained:

Mass (in Kg) = 8.75×10⁷ Kg

Mass (in mg) =?

Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:

1 Kg = 1000 g

Therefore,

8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg

8.75×10⁷ Kg = 8.75×10¹⁰ g

Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.

Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:

1 g = 1000 mg

Therefore,

8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g

8.75×10¹⁰ g = 8.75×10¹³ mg

Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

The geometry of PBr₃ is trigonal pyramidal. Therefore, option A is correct.

Trigonal pyramidal geometry refers to the molecular geometry around a central atom in a molecule or ion where there are three bonded atoms and one lone pair of electrons. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one non-bonding pair of electrons.

The term "trigonal" refers to the arrangement of the three bonding pairs, which are positioned in a flat, triangular shape around the central atom. The term "pyramidal" indicates that the lone pair of electrons occupies the fourth position, giving the molecule a three-dimensional pyramid-like shape.

[Rn]7s25f14

Explanation:

[tex][Rn]5f^{14}7s^2[/tex] is the electron configuration for nobelium (No).

Explanation:

Given:

The element nobelium.

To find:

The electronic configuration of nobelium

Solution:

The atomic number of nobelium is 102.

The number of protons = Atomic number = 102

The number of electrons = Number of protons = 102

There are 102 electrons in atom nobelium and they will be filled according to the Aufbau rule that the electron will be filled in a subshell with lower orbital energy.

The electronic configuration of nobelium :

[tex][No]=1s^22s^22p^63s^23p^63d^{10}4s^24p^64d^{10}5s^25p^64f^{14}5d^{10}6s^26p^65f^{14}7s^2[/tex]

Or we can also write the above electronic configuration as:

[tex][No]=[Rn]5f^{14}7s^2[/tex]

[tex][Rn]5f^{14}7s^2[/tex] is the electron configuration for nobelium (No).

Neon is transparent opaque as it is light, colorless and order less inert noble gas.

Noble gas are defined as the element that belong to group 18 of the modern periodic table.

It is also known as inert gas or aerogene.

Noble gas are light, transparent, colorless and order less gases.

They are the group of six inert or non reactive gases.

Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.

Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.

Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.

Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg.

Explanation:

The following data were obtained from the question:

Mass in Kg = 67 kg

Mass in mg =.?

Thus, we can obtain the mass in milligrams (mg) as follow:

1 kg = 1×10⁶ mg

Therefore,

67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg

Therefore, 67 kg is equivalent to 6.7×10⁷ mg
