Answer:

C₅H₁₀SO₂

Explanation:

From the given information:

The objective is to identify the empirical formula of the compound.

To start with determining the mass of carbon from carbon dioxide; we have:

[tex]Mass \ of \ Carbon = \dfrac{molar \ mass \ of \ C }{molar \ mass \ of \ CO_2}\times mass \ of \ CO_2[/tex]

Mass of carbon = 12/44 × 57.271  mg

Mass of carbon = 0.2727 × 57.271  mg

Mass of carbon = 15.6178 mg

The mass of hydrogen is:

[tex]Mass \ of \ Hydrogen= \dfrac{molar \ mass \ of \ H }{molar \ mass \ of \ H_2O}\times mass \ of \ H_2O[/tex]

[tex]Mass \ of \ Hydrogen= \dfrac{2\times 1.008 }{18}\times 23.444 \ mg[/tex]

Mass of hydrogen = 2.6257 mg

The mass of sulphur is:

[tex]Mass \ of \ Sulphur = \dfrac{molar \ mass \ of \ S }{molar \ mass \ of \ SO_2}\times mass \ of \ SO_2[/tex]

Mass of Sulphur = [tex]\dfrac{32.07}{64.06} \times \dfrac{9.656}{1} \times \dfrac{32.149}{ 22.345}[/tex]

Mass of Sulphur = 6.9550 mg

The Mass of oxygen can now be = mass of (Sample - Carbon - Hydrogen - Sulphur)

= (32.149 - 15.6178 - 2.6257 - 6.9550)g

= 6.9505 g

Recall that:

number of moles = mass/molar mass

Thus:

The moles of C : H : S : O are:

[tex]= \dfrac{15.6178}{12} : \dfrac{2.6257}{1.008} : \dfrac{6.9550}{32.07} : \dfrac{6.9505}{16}[/tex]

= 1 : 2 : 0.2 : 0.4

Divide by the smallest; we have:

= 1/0.2 : 2/0.2 : 0.2/0.2 : 0.4/0.2

= 5 : 10 : 1 : 2

Thus, the empirical formula is = C₅H₁₀SO₂

Answer:

1) 3Fe + 2O(2, this is the subscript) - Fe(3)O(4)

2) 2Sr + O(2) - 2SrO

3) Sn + 2NaOH - Na(2)SnO(2) + H(2)

4) 2K + Br(2) -2KBr

5) 2C(8)H(18) + 25O(2) - 16CO(2) + 18H(2)O

Answer:

same number of protons differnt number of nuetrons

Explanation:

Atoms of manganese- 55, iron-56, and nickel-58 have same number of neutrons and  different number of protons.

It is same as the atomic number of an element.

It is the difference between the mass number and atomic number or number of protons.

No. of protons =  25

No. of neutrons = 30

No. of protons =  26

No. of neutrons = 30

No. of protons =  28

No. of neutrons = 30

Thus, the number of neutrons in all the atoms is same i.e. 30.

Answer: Chemical bond. Two atoms in the same molecule are linked together by a chemical bond. Write "bond" in the blank.

Two atoms in the same molecule are linked together by a chemical bond.

A chemical bond is defined as the formation of a chemical compound by the union of  two or multiple atoms, ions, or molecules, the firmness can be evaluated by the type of its chemical bond.

Ionic Bond is a type of chemical bond where relocation of electrons from one atom to alternative atom,  one atom creates a negative charge called as anion while another atom creates a positive charge called cation.

The covalent bond defines the distribution of electrons among atoms, it can be either polar or non polar in nature and the electrons are united unevenly in polar covalent chemical bonding.

Hydrogen Bonding is  a fragile procedure of chemical bonding, this type of polar covalent bonding occur between oxygen and hydrogen where  hydrogen develops a partial positive charge in the formation of the water.

Answer:

D

Explanation:

Answer:

A. A galvanic cell generates electrical current, and an electrolytic cell uses electrical energy to cause redox reactions to occur.

Explanation:

A galvanic cell produces electrical energy through the conversion of chemical energy whereas the electrolytic cell carries out the conversion of the electrical energy/current supplied to it into chemical energy. The reaction that takes place in the galvanic cell is spontaneous which is responsible for the electrical energy that is produced. The redox reaction in the electrolytic cell is not spontaneous. Electrical energy has to be supplied to it in order to initiate the reaction.

Answer: B.

Explanation:

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

Explanation:

Helium has two electrons in its energy shell, while argon and neon have 8 electrons in their valence shells. As these have maximum number of electrons in their valence shells, they do not have any tendency to combine with other elements. Hence, they have a valency equal to zero.

There are 2.06 x 10²⁴ atoms

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³  particles

Moles can also be determined from the amount of substance mass and its molar mass

Answer:

it takes more than 12g of nitrogen gas to make a mole

Answer:

0.86 mol N

Explanation:

To convert between grams and moles, you need the molar mass of the substance. The molar mass of nitrogen is 14.01g/mol. This is used as the unit converter.

[tex]12gN*\frac{1molN}{14.01gN} = 0.85653 mol N[/tex]

Then round the answer to the lowest number of significant figures = 0.86 mol N.

10 J = 2.39 cal = 2.39 x 10⁻³ kcal

The joule is one unit of energy. energy itself can be expressed in units such as calories, BTU, kg⋅m²s⁻²

An example of energy calculation is the calculation of heat in heat transfer

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

10 J if we convert into calories and kcal

[tex]\tt 1~J= 0.239~cal\\\\10~J=2.39~cal\\\\2.39~cal=2.39\times 10^{-3}~kcal[/tex]

Answer:

Explanation:

Let final temperature be T .

vapor is at 102⁰C

loss of heat by vapor in turning into water at 100⁰C

= 2.6 x 2 x 1.996 + 2.6 x 2260 = 5886.37 J

loss of heat to lower temperature to T

2.6 x 4.186 x ( 100 - T )

1088.36 - 10.88 T

Total heat loss = 5886.37 + 1088.36 - 10.88 T

= 6974.73 - 10.88 T

heat gain by silver to gain temperature from 1⁰C to T⁰C

= 1250 x ( T - 1 ) x .235 = 293.75 T - 293.75

heat gain = heat loss

293.75 T - 293.75  = 6974.73 - 10.88 T

304.63 T = 7268.48

T = 23.86°C .
