Answer:

because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation

Explaination:

the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.

Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.

It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.

Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.

Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.

Oxidation state is defined as the total number of electrons that have been deleted or added to an element.

It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.

Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

Answer:

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.

Explanation:

:)

The number of atoms present in two water molecules is 6 atoms. 4 hydrogen atoms and 2 oxygen atoms.

Atoms are the basic unit of a substance. An atom is made of a nucleus, protons, neutrons and electrons. Different atoms combines to form a molecule and molecules combines to form compounds.

Water has the formulas H₂O, thus one molecule of water contains 2 hydrogen and one oxygen. Therefore, two molecules of water that is (H₂O)₂ have 4 hydrogen and 2 oxygens thus, a total of 6 atoms.

Hence, the number of atoms present in two molecules of water is 6.

Explanation:

Given parameters:

  Atomic number of zinc  = 30

  Mass number of zinc = 65

Unknown

  Number of neutrons  = ?

Solution:

The mass number of an atom is the sum of its protons and neutrons;

     Mass number  = Protons + neutrons

Atomic number is the number of protons in an atom;

   Atomic number  = Protons

So;

     Mass number  = Atomic number + Neutrons

Neutrons  = Mass number  - Atomic number

 Neutrons  = 65 - 30  = 35

The number of neutrons in the atom is 35

Answer:

Explanation:

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

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

From the question

The mass of one brick is 50 g

the volume of one brick is 10 cm³

Since the student had 5 bricks

Total mass = 5 × 50 = 250 g

total volume = 5 × 10 = 50 cm³

So the total density is

[tex]density = \frac{250}{50} = \frac{25}{5} \\ [/tex]

Answer:

He will not have hard-boiled eggs for breakfast

Explanation:

The given parameters are;

The elevation at which the base camp of the hiker is located = 5,300 meters

The boiling point of water at the elevation of the base camp = 82°C

The temperature required to cook the raw egg = 100°C

Therefore, we have;

The temperature of the boiling water at the given elevation of the base camp 82°C < The temperature required to cook the raw egg 100°C

Therefore, the eggs will not be hard boiled.

The hiker won't have hard-boiled eggs for breakfast as a result of the

boiling point of water being less than 100⁰C.

The boiling point decreases with an increase in altitude. The hiker was at

5,300 meters above sea level which made the boiling point of water to be

decreased to 82⁰C.

Since the water isn't able to achieve the boiling point of 100⁰C, then the raw

egg won't be hard boiled for breakfast.
