[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).

A. 2s is incorrect, the right arrow should be pointing downwards.

B. In 2p, the last box has 3 arrows. This is invalid. Each box can only store 2 arrows(electrons).  The last arrow should be moved to a 3p orbital (new box).

C. In this one, the arrows switched directions (left is down and right is up). You could fix each box or just the last one (in 3p) to point downwards.

Answer:

x100.

Explanation:

Na2CO3 (aq) + CaCl2(aq) → CaCO3 (s) + 2 NaCl (aq)

For example, if we use 2.00 g CaCl2 x 1 mole = 0.0180 mole CaCl2

111 g CaCl2

and mix it with 2.00 g Na2CO3 x 1 mole = 0.0189 mole Na2CO3

106 g.

AB + CD → CB + AD, where A and C are cations and B and

D are anions

Answer:

x100 this is the answer I didn't do explanation sorry for that

Explanation:

Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.

Both the kinetic energy and potential energy are directly proportional to the mass of the object. Hence, increasing the mass will increase the kinetic and potential energy of the pendulum.

The kinetic energy of an object is generated by virtue of its motion. Whereas, the potential energy is generated by virtue of its position. hen the object is at rest, the energy is stored in it in the form of potential energy. When the object starts moving, its potential energy starts to converts to kinetic energy.

The kinetic energy of an object is related to its mass and velocity by the equation:

Ke = 1/2 mv²

Potential energy  P = mgh

where, g is the acceleration due to gravity and h is the height of the object from the surface.

Hence, both potential energy and kinetic energy are directly proportional to the mass of the object. An increase in mass increase both form of energy of the object.

Therefore, the kinetic and potential energy of the pendulum increases with mass.

The crystals of igneous rock are formed due to different chemical composition, size and structure of the rocks

The crystals of an igneous rock are used to classify its own because the crystals of igneous rock are formed due to different chemical composition as well as size and structure. Igneous rocks are the type of rocks which are formed when magma cools and change into solid state.

They are classified on the basis of grain size, silica content, and silica saturation. The igneous rock is depend on the rate of cooling i.e. slow cooling causes the formation of large crystals whereas fast cooling produces small crystals. The igneous rocks are classified according to their chemical composition.

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.

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.
