Write the general formula of an alkane and use this to predict the 97th member
of the alkane series.

Answers

Explanation:

The general formula of an alkane is given as;

        CₙH₂ₙ₊₂

n is the number of the member;

 For the 97th member in the series;

 n  = 97;

 2n + 2  = 2(97) + 2  = 196

So, the 97th member is;

                C₉₇H₁₉₆

This is how to apply the formula of alkanes which are saturated hydrocarbons to find any member of the series.

Answers

the number of protons
The number of atoms

who know how to do this thank you

Answers

Number of neutrons :

Argon=22

Boron=6

Further explanation

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

Argon has an atomic number of 18 and a mass number of 39,948

number of neutrons =

[tex]\tt 39.948-18=21,948\approx 22[/tex]

Boron has an atomic number of 5 and a mass number of 10,811

number of neutrons =

[tex]\tt 10.811-5=5.811\approx 6[/tex]

What is the specific heat of a substance that absorbs 1000 joules of heat when a sample of 25 g of the substance increases in temperature from 10.0C to 60.0C

Answers

Answer:

1250000

Explanation:

Specific heat is mass times specific heat capacity times change in temperature to get chance in temperature minus the old temperature from the new temperature then complete equation hence 25g×1000j×(60-10)

25g×1000j×50

=1250000g/j/degree Celsius

Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?

Answers

Answer:

Explanation:

7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C

= 2.1 g of C .

This will be contained in 3.256 g of isopentyl acetate

3.156 g of H₂O will contain 2 x 3.156 / 18 g of H

= .351 g of H

This will be contained in 3.256 g of isopentyl acetate

Rest will be oxygen

amount of oxygen in 3.256 g of isopentyl acetate

= 3.256 - ( 2.1 + .351 )

= .805 g

ratio of C , H , O in isopentyl acetate

= 2.1 g : .351 g : .805 g

2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles

= .175 : .351 : .05  ratio of moles

= 3.5 : 7.02: 1

= 7 : 14 : 2

The reaction for the combustion of acetylene is shown. Explain why this reaction is a redox reaction by identifying the oxidation numbers that change, what is oxidized, what is reduced, and what happens to the electrons during the reaction. 2C2H2 + 5O2 → 4CO2 + 2H2O

Answers

Answer:

2 C2H2 (g) + 5 O2 (g) → 4 CO2 (g) + 2 H2O (l)

Explanation:

Redox reaction: In this type of reaction, oxidation and reduction reaction occurs simultaneously in same chemical reaction.

2C_2H_2+5O_2\rightarrow 4CO_2 + 2H_2O2C

This reaction is a redox reaction :

Removal of hydrogen or addition of oxygen is termed as oxidation. in above reaction, removal hydrogen from acetylene gives carbon-dioxide.

Removal of oxygen or addition of hydrogen is termed as reduction. in above reaction, removal of one oxygen atom from oxygen molecule with addition of two hydrogen atoms gives water

The oxidation number of carbon in acetylene is -2.

The oxidation number of carbon in carbon-dioxide= +4

Oxidation number of carbon increases after the reaction which means that carbon is getting oxidized.

The oxidation number of oxygen in oxygen gas = 0

The oxidation number of oxygen in water = -2

Oxidation number of oxygen decreases after the reaction which means that oxygen is getting reduced.

The electrons released during oxidation are transferred to the species which are undergoing reduction reaction.

Answer:

Just put this, or something like it:

The oxidation number of carbon changes from -1 to +4.

The oxidation number of oxygen changes from 0 to -2.

Carbon is oxidized.

Oxygen is reduced.

Electrons are transferred from carbon to oxygen.
