Answer:

Energy of an electron is quantinized means the electrons can possess only specific individually separated values.

These energy levels are stable and are stationary along with different energy value.  The electron remains in the state until energy is absorbed or released.

The electrons absorb energy when it moves from lower energy state to higher energy state. The electrons lose energy when it moves from higher energy state to lower energy state and thus emit radiations corresponding to the energy gap and is called as quanta.

Answer:

68133080.02 g

Explanation:

I believe that the question is to find the mass of air in the room and not the molar mass of air since the molar mass of air was already given in the question as 28.97 g/mol.

Now, if 1 mole of a gas occupies 22.4 L

x moles of air occupies 52,681,428.8 Liters

x = 1 * 52,681,428.8 /22.4

x = 2351849.5 moles of air

Now, number of moles = mass/ molar mass

but molar mass = 28.97 g/mol

2351849.5 = mass/28.97

mass = 2351849.5 * 28.97

mass = 68133080.02 g

Explanation:

Answer:

a) 2.632 kg

b) 41.36 kg

Explanation:

Given data:

Mass of CO react = ?

Mass of Fe formed = 3.50 Kg (3.50 /1000 =3500 g)

Mass of CO₂ formed = ?

Solution:

Chemical equation;

Fe₂O₃ + 3CO     →   2Fe + 3CO₂

Number of moles of Fe:

Number of moles = mass/molar mass

Number of moles =  3500 g/55.85 g/mol

Number of moles = 62.67 mol

now we will compare the moles of iron with CO.

            Fe         :       CO

             2          :       3

          62.67     :        3/2×62.67 = 94 mol

Mass of CO:

Mass = number of moles × molar mass

Mass = 94 mol × 28 g/mol

Mass = 2632 g

In kilogram:

2632g × 1 Kg /1000 g

2.632 kg

Now we will compare the moles of Fe with CO₂

                 Fe         :           CO₂

                  2          :           3

               62.67     :        3/2×62.67 = 94 mol

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 94 mol × 44 g/mol

Mass = 4136 g

In kilogram:

4136g × 1 Kg /1000 g

41.36 kg

Answer:

1s²2s²p⁶3s²p⁴

Explanation:

An atom that is in the ground state has not lost or gained electrons. If we look at the Periodic Table, we can see that the electron configuration of the sulfur atom (S) is [Ne]3s²p⁴. Since the electron configuration of Ne is 1s²2s²p⁶, the complete electron configuration is 1s²2s²p⁶3s²p⁴.

B. insulator

The materials which prevents flow of electric current through it is called insulators. Thus, option B is correct. The materials which allow the current are conductors.

There are three types of substances based on their conducting nature. The materials which are highly conducting electrically at normal condition are called conductors. For example: metals.

Materials which does not conduct electricity at any condition are called insulators. Insulators prevent the flow of free electrons and thus are resistant to electric shock, example: wood

Some materials which does not conduct at normal temperature but, will conduct at higher temperature and also upon  mixed with other materials are called semiconductors. example:  silicon. Therefore, option B is correct.

Answer:

work and power increases or decreases opposite of the mass

Explanation:

This Is beacuse Work is the product of Mass, Gravity, and Height

Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree celsius of one gram of a substance. Therefore, the initial temperature of water is  27.0°C.

Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.

Mathematically,

Enthalpy=mass of solution× specific heat capacity of solution ×Change in temperature.

Enthalpy=1000 J

mass of water=0.05kg

Change in temperature=50-initial

specific heat capacity of solution=4.2

Substituting all the given values we get

1000 J= (0.05kg)(4.2)(50-initial)

initial temperature= 27.0°C

Therefore, the initial temperature of water is 27.0°C.

Explanation:

Hehe I remembered how...

Answer:

See explanation

Explanation:

Dalton's atomic theory furnished us with a basis to discuss the theory of atoms. However, not all his ideas holds up under the scruitiny of morden science.

He postulated that atoms were 'indivisible' the discovery of subatomic particles indeed show that there are smaller particles than atoms.

His postulation that atoms can neither be created nor destroyed does not hold water today because atoms are being created in nuclear reactors.

He said that atoms of all elements are exactly alike. Today we know there are isotopes of elements which are not exactly alike.

We can see that the Dalton's atomic theory did not take cognisance of the important role of subatomic particles in studying the structure of the atom. Modern atomic theory tries to look at the importance of these particles in the understanding the structure of the atom.

C. oxidation ..........

The given reaction is the breaking of the carbohydrate C₁₂H₂₂O₁₁ into 12 C and 11 H₂O. Hence, it is a decomposition reaction .

A decomposition reaction is a type of chemical reaction in which a compound breaks down into two or more simpler substances, either through heat, light, or an electrical current.

In a decomposition reaction, a single reactant is converted into two or more products, which can be elements or compounds.

The general equation for a decomposition reaction can be written as:

AB → A + B

where AB is the reactant and A and B are the products.

Decomposition reactions are important in many chemical processes, such as the breakdown of organic matter in soil, the production of industrial chemicals, and the functioning of biological systems.

P4O10 + 6H2O → 4H3PO4

so 1,6,4

The balanced equation is :

                                P₄O₁₀ + 6 H₂O ⇒ 4 H₃PO₄

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

The unbalanced equation is -

                              P₄O₁₀ + H₂O ⇒ H₃PO₄

There are 4 P on the reactant side, to balance P atom we need to add P on the product side also.

                             P₄O₁₀ + H₂O ⇒ 4 H₃PO₄

To balance the O atom on both sides, add coefficient 6 in front of water and this gives the balanced equation is written as -

                              P₄O₁₀ + 6 H₂O ⇒ 4 H₃PO₄

Therefore,

The balanced equation is :
