Answers

Answer 1
I’m pretty sure it c hope that helped
Answer 2

Answer:

E. A conductor is needed for electricity to flow in a circuit.

Explanation:

Electric current can flow without a resistor, as in short circuit.

A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.

Without a switch, electricity can flow in a circuit, switch is only used to close or open the circuit.

Thus, the only correct option is  E

E. A conductor is needed for electricity to flow in a circuit.

Repeat this calculation using Slater's rules to estimate the screening constant, S, and calculate Zeff for these two ions. Express your answers using two decimal places. Enter your answers numerically separated by a comma. 50 A 6 A 0 21 ? S. Zeff C, Zeff K+ =

Answers

Answer:

Cl^- = 5.75

K^+ = 7.75

Explanation:

Now let us calculate the effective nuclear charge four K^+ and Cl^- from Slater's rule.

Given that Cl^- and K^+ has electronic configuration of; [Ne] 3s2 3p6 (they are isoelectronic species)

We compute S as follows;

For n - 2 level, S= 1

For n - 1 level, S= 0.85

For ns,np level S= 0.35

Note: S= screening or shielding constant

1s2, S=2 ×1 = 2

2s2 2p6, S= 8×0.85 = 6.8

3s2 3p6, S= 7 × 0.35 = 2.45

The electron under study is not considered hence seven out of eight electrons in the shell are considered

Hence

S= 2 + 6.8 + 2.45 = 11.25

Since Cl^- has 17 electrons;

Zeff(Cl^-) = 17 - 11.25 = 5.75

For K^+

Zeff = 19 - 11.25 = 7.75

Which compound contains nitrogen with an oxidation number of +3?

Answers

Answer:

Nitrous Acid [tex]N_{2}O_{3}[/tex]

Nitrogen is in the +3 oxidation state in N2O3. Nitrous acid is a weak acid.

The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂. Nitrous acid is a weak acid.

What do you mean by oxidation state ?

The term oxidation state is defined as the total number of electrons that an atom either gains or loses in order to produce a chemical bond with another atom. The oxidation state is also called as oxidation number.

The formula for calculating oxidation states would be : The Highest Oxidation State for a Transition metal = Number of Unpaired electrons + Two s-orbital electrons.

The compound contains nitrogen with an oxidation number of +3 is N₂O₃ because it can acquire three electrons to form a chemical bond and to complete its outermost orbit (octet).

Thus, The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂.

Which is the state of matter shown in this figure ?

Answers

Answer:

It looks like a solid because they are densely packed kind of like an ice cube

Explanation:

The state of matter shown in this figure is solid state, because the particles are arranged densely in the form of cube.

What is solid state ?

The state of matter known as a solid has a definite form, mass, and volume. Changing the temperature causes extremely little variations in volume to be seen. For instance, sand, wood, copper, ice, etc., cannot be crushed.

One of the three fundamental states of matter, along with liquid and gas. Since atoms' energy drops when they adopt a comparatively organized, three-dimensional structure, solids can emerge from liquids or gases.

Because solids have specific mass, volume, and form, their component particles are arranged compactly. Between molecules, there is little intermolecular space. As a result, there is a strong force between the constituent particles (atoms, molecules, or ions).

Thus, option A is correct.

What is the relationship between the atomic mass of an element and a mole of that element's atoms?

Answers

Answer:

Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).

Explanation:

The relationship between the given terms is provided below throughout the below segment.

One mole of such a component's atomic weights is approximately equivalent to that component's atomic mass. This same atomic mass of the oxygen element, for example, is about 16g. As a result, one mole containing oxygen atoms equals 16g of oxygen ([tex]O_2[/tex]). 1 mole containing oxygen atoms weighs 16g.

We can say that,

→ [tex]1 \ mole \ in \ gram \ of \ an \ element = Atomic \ mass \ of \ an \ element[/tex]

Which of the following models best demonstrates the law of conservation of mass??
(LOOK AT THE PICTURES)!!

Answers

Answer:

i think its D

Explanation:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Taking into account the law of conservation of mass,

The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "The mass is not created or destroyed, only transformed."

This means that the reagents interact with each other and form new products with different physical and chemical properties than those of the reagents. And this is because the atoms of the substances are ordered differently.

But the quantities of the masses involved in a given reaction must be constant throughout it, that is, they will not have changed in their proportions when the reaction ends. Then the mass before the chemical reaction is equal to the mass after the reaction.

The exception to the rule is nuclear reactions, in which it is possible to convert mass into energy and vice versa.

Finally, the correct answer is option A. because the atoms of the substances are ordered differently, this is the reagents interact with each other and form new products.

Answers

Answer:

Explanation:

M(s) → M (g ) + 20.1 kJ --- ( 1 )

X₂ ( g ) → 2X (g ) + 327.3 kJ ---- ( 2 )

M( s) + 2 X₂(g) → M X₄ (g ) - 98.7 kJ ----- ( 3 )

( 3 ) - 2 x ( 2 ) - ( 1 )

M( s) + 2 X₂(g) - 2 X₂ ( g ) - M(s)  → M X₄ (g ) - 98.7 kJ -  2 [ 2X (g ) + 327.3 kJ ] - M (g ) - 20.1 kJ

0 = M X₄ (g ) - 4 X (g ) - M (g ) - 773.4 kJ

4 X (g ) +  M (g ) =  M X₄ (g ) - 773.4kJ

heat of formation of M X₄ (g ) is - 773.4 kJ

Bond energy of one M - X bond =  773.4 / 4 =  193.4 kJ / mole
