Since you have a

⋅

6 moles of water

1 mole glucose

⋅

18.0 g

1 mole water

=

g

This represents your theoretical yield. If the percent yield is 100%, the actual yield will be equal to the theoretical yield. However, after you do the experiment you discover that only 6.50 g of water were produced.

Since less than what was calculated was actually produced, it means that the reaction's percent yield must be smaller than 100%. This is confirmed by

When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. So, the correct option is C, attraction. This is because opposite magnetic poles attract each other, while like magnetic poles repel each other.

A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of charged particles, such as electrons, protons, and ions. A magnetic field can be produced by a magnet, an electric current, or a changing electric field.

When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. This is because the magnetic field lines of the two magnets interact in such a way that they try to align with each other. Since opposite magnetic poles attract each other, the North Pole of one magnet will be attracted to the South Pole of the other magnet.

The magnetic force between the two magnets depends on the strength of the magnetic field and the distance between the magnets. The closer the magnets are, the stronger the magnetic force will be.

Therefore option C, attraction is correct.

Answer:

[tex]186.5\ \text{K}[/tex]

Explanation:

[tex]V_1[/tex] = Initial volume = 0.05 L

[tex]V_2[/tex] = Final volume = 0.1 L

[tex]T_1[/tex] = Initial temperature

[tex]T_2[/tex] = Final temperature = 373 K

From the ideal gas law we have

[tex]PV=nRT[/tex]

So

[tex]V\propto T[/tex]

[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\Rightarrow T_1=\dfrac{V_1}{V_2}\times T_2\\\Rightarrow T_1=\dfrac{0.05}{0.1}\times 373\\\Rightarrow T_1=186.5\ \text{K}[/tex]

The intial temperature is [tex]186.5\ \text{K}[/tex].

The modern periodic table consists of the elements which are arranged in the increasing order of their atomic numbers. The element 'C' belongs to 14th group of the periodic table. The correct option is A.

The orbital diagrams are the pictorial representation of the electrons in an atom. The orbital diagrams are mainly based on the Auf Bau principle, Pauli's exclusion principle and Hund's rule of maximum multiplicity.

According to Auf Bau principle, the electrons are arranged in the orbitals in the increasing order of their energies. The pauli's exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers.

The hund's rule states that the unpaired electrons in the orbitals have parallel spins. The atomic number of 'C' is 6, and its electronic configuration is 1s²2s²2p².

Thus the correct option is A.

2. ground state Fe :  [Ar] 4s² 3d⁶

Aufbau rule

Electrons occupy orbitals of the lowest energy level

Charging electrons in the sub-shell uses the following sequence:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  

So the correct choice of answer is B.

Ground state is the state of electrons filling skins with the lowest energy levels.

Excited state is the state of electrons which occupy a higher energy level

The atomic number of Fe = 26, so electrons=26

Ground state configuration of Fe : [Ar] 4s² 3d⁶ or
