Answer:

6. 53 is the answer. Hope this helps:)

The number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.

An atomic number may be defined as the number of protons in the nucleus of an atom that significantly represents the characteristic of a chemical element and determines its specific place in the modern periodic table.

According to the modern periodic table, an element that has an atomic number of 53 is known as Iodine. Its electronic configuration is [tex]1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^1^0, 4p^6, 5s^2, 4d^1^0, 5p^5[/tex]. Thus, according to this electronic configuration, the total number of d electrons are [tex]3d^1^0 and 4d^1^0[/tex].

Therefore, the number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.

Answer:

The heat is transferred from your hand to the ice, this is because, as we know, heat gets transferred from a hot object to a colder object.

In this case, our hand is clearly hotter than the ice cube.

Therefore, the heat is transferred from your hand to the ice cube.

Answer:

1. linear (A)

2. trigonal-planar (C)

3. tetrahedral (B)

4. linear (A)

Explanation:

Just did it on Edge 2020

The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

The Valence Shell Electron Pair repulsion theory gives us a basis for predicting the shape of molecules. The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

In the image shown, We can see that in HCN , carbon is the central atom and is surrounded by two atoms and no lone pairs. Since there are two electron domains around the central atom, the molecule is linear.

In the second structure, BH3 has boron as its central atom. Three electron domains surround the central atom hence the molecule is trigonal planar.

The volume of cylinder = 7.948 cm³

Further explanation

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the aquarium is almost the same as the beam namely:

V = length x width x height

The volume of a cylinder can be formulated :

r = radius

h = height

Diameter of cylinder = 1.25 cm

Answer: 5 orbitals

Explanation:

Each d subshell has 5 orbitals, with 10 electrons. So it's like for every orbital, there are 2 electrons. Look at orbital diagrams (if your teacher made you draw them), and you will see that an arrow pointing both UP AND DOWN represent 2 electrons (arrow upward=1 electron, arrow downward=1 electron)

Here, we are required to determine how many orbitals does the d subshell have, and how many electrons can fit in the d subshell.

The d subshell is first recorded in the shell with energy level 3.

The orbitals in an atom are organized into different layers or electron shells. The d subshell has 5 orbitals in it.

This is evident from the formular; 2l + 1.

where l = 2 for the d subshell.

As with any sub-orbital, the sub-orbitals in the d-subshell also contain 2 electrons each.

According to Pauli's exclusion principle, the two electrons in each must have opposing spin.

Using the molar mass of Gold (given in a periodic table) which is 196.97g/mol

you have

[tex](3.60*10^-5 g) *\frac{1moles}{196.97g}[/tex]

you always arrange the equation in a way to cancel whatever you don't want (grams) and leave what you do want (moles). Here grams cancel (top and bottom), so you're left with:

Explanation: just took the test

Since water has a high specific heat, that results in water being able to store/require more energy in order to change it’s temperature. Since San Francisco is so close to water, that would mean that it’s temperature should vary less since water would be able to keep the temperature around the same value even if there was an increase or decrease in thermal energy.  

Answer:

18

Explanation:

The volume of the gas should be 1. 18.0 L

Since A sample of a gas occupies 6.00 liters at a temperature of 200 K. If the pressure remains constant and the temperature is raised to 600 K

So here the volume of the gas should be

= 600 * 6 /200

= 18.0 L

hence, the first option is correct.

A lion preying  on a herd of gazelle is not an example of how biotic factors interact with abiotic factors in an ecosystem.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

Molecular Mass

Explanation:

It's asking for the numerical quantity. That quantity would be the Molecular Mass. Take the sample mass and divide it by the molecular mass to get the number of moles.

(14g N * 2) + (1g H *4) = 32g / mol of N2H4

To get # of moles, divide the sample mass by the molecular mass

25g / 32g = 0.78125 moles
