How Do The Percent Compositions For C3H6 And C4H7 Compare?A. They Are The SameB. C4H8 Has A Higher Percentage

Answers

Answer 1

A. They are the same

Further explanation

Given

C3H6 and C4H8

Required

The percent compositions

Solution

C₃H₆(MW = 42 g/mol)

%C = 3.12/42 x 100% = 85.71%

%H = 6.1/42 x 1005 = 14.29%

C₄H₈(MW=56 g/mol)

%C = 4.12/56 x 100% = 85.71%

%H = 8.1/56 x 100%=14.29%

So they are the same, because mol ratio of C and H in both compounds is the same, 1: 2

To convert between units, you need to know the relationship between units. For example, one mile equals 5280 feet. This relationship can now be used as a conversion factor, set up as required by the question. For each conversion, choose the correct arrangement of the conversion factor and complete the calculation 1. Convert 7860 feet to miles 7860 feet x (A)
A: 1 mile
B: 5280 feet 7860 feet miles 2. Co 0.5 miles to feet 0.565 miles x (C) TD
C: Choose...
D: Choose 0.565 miles feet

Answers

Answer:

1. 7860 Feet = 1.488 miles

A= 1

B= 5280

2. 0.565 miles = 2983.2 feet

C= 0.565

D= 1

Explanation:

1. Convert 7860 feet to miles

1 miles= 5280 feet

1 Feet= 1/ 5280 miles

7860 Feet= 7860 ( 1/ 5280) miles

7860 Feet = 1.488 miles

A= 1

B= 5280

2. Convert 0.565 miles to feet

1 mile= 5280 feet

0.565 miles = 5280 feet * (0.565/1)

0.565 miles = 2983.2 feet

C= 0.565

D= 1

We see that when we have to convert feet into miles we divide the number by 5280 because feet are smaller than miles. Similarly when we have to convert miles into feet we multiply by the given number because miles are greater than feet.

The above method used is called the unitary method but we should always keep in mind that conversion from smaller to bigger units require divsion and from bigger to smaller units require multiplication.

Answers

Given

Reaction

C+02 = CO2

Required

The equilibrium constant

Solution

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction  

pA + qB -----> mC + nD  

[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]

2 NaOH (s) + CO2(g) → Na2CO3 (s) + H20 (I) How many grams of water can be produced with 1.85 moles of NaOH​

Answers

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Moles of H2O = 1.85mol * (1/2) = 0.925mol.

Mass of H2O = 0.925mol * (18g/mol) = 16.65g.

Answer:

16.65 grams of water can be produced with 1.85 moles of NaOH.

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Number of moles of water = (1/2)×1.85= 0.925 moles

Molar mass of water (H2O) = 18g/mol

Mass of the right water = 18g/mol×0.925 mol=16.65 grams

What is creating our Earth's Magnetic field?
1) Our Earth's iron liquid outer core rotating around the solid inner core
2) Our Earth having a stationary inner core
3) Our Earth having rocky center
4) All of the above

Answers

Answer:

1) Our Earth's iron liquid outer core rotating around the solid inner core

Explanation:

The earth's magnetic field or the geomagnetic field is produced as a result of the earth's iron liquid outer core rotating around the solid inner core.

This produces the earth's magnetic field.

The earth's core is made up of solid and liquid region. Only the densest elements are found within this region. So, the core is made up of metals which are mainly iron and nickel. The outer core is liquid or molten iron and the inner core is solid. The molten iron and nickel in the outer core moves around the inner core and generates the currents which induces a magnetic field round the earth.

The following chemical reaction takes place in aqueous solution:
AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)
Write the net ionic equation for this reaction.

Answers

The net ionic equation : Ag⁺(aq)+l⁻(aq) ⇒ Agl(s)

Further explanation

Given

Reaction

AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)

Required

The net ionic equation

Solution

The equation of a chemical reaction can be expressed in the equation of the ions

In the ion equation, there is a spectator ion that is the ion that does not react because it is present before and after the reaction  

When these ions are removed, the ionic equation is called the net ionic equation  

AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)

Ag⁺(aq)+F⁻(aq)+Na⁺(aq)+l⁻(aq) ⇒ Agl(s)+Na⁺(aq) + F⁻(aq)

Ag⁺(aq)+l⁻(aq) ⇒ Agl(s)
