Assuming a 25% efficiency, how many Calories would a horse need to consume to work at 1.0 hp for 2.0 hh ?

Answers

Answer:

E = 7.11 × [tex]10^{-7}[/tex]  Cal

Explanation:

given data

efficiency = 25 %

solution

first we get here E by the power that is express as

p = [tex]\frac{E}{t}[/tex]     ...........1

E = p × t

E = 1 ×  2 × [tex]\frac{1hp}{746w} \times \frac{1hr}{3600 s}[/tex]  

E = 7.447 × [tex]10^{-7}[/tex] J

and

Ein is get by efficiency

Ein = [tex]\frac{Eout}{\eta }[/tex]        ..................2

Ein = [tex]\frac{7.447 \times 10^{-7}}{.25 }[/tex]

Ein = 29.788 × [tex]10^{-7}[/tex]  J

so required energy is

E = 29.788 × [tex]10^{-7}[/tex]  ×  [tex]\frac{1Cal}{4.184J}[/tex]

E = 7.11 × [tex]10^{-7}[/tex]  Cal

6. What is the equilibrium constant for the following reaction?
C+02 = CO2

Answers

[tex]\tt Kc=\dfrac{[CO_2]}{[C][O_2]}[/tex]Further explanation

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]

Assuming that only the listed gases are present, what would be the mole fraction of oxygen gas be for each of the following situations?

A gas sample of 2.31 atm of oxygen gas and 3.75 atm of hydrogen gas that react to form water vapor. Assume the volume of the container and the temperature inside the container does not change.​

Answers

The mole fraction of oxygen gas : 0.381

Further explanation

Given

2.31 atm Oxygen

3.75 atm Hydrogen

Required

The mole fraction of Oxygen

Solution

Dalton Law's of partial pressure

P tot = P₁ + P₂ + ..Pₙ

Input the value :

P tot = P O₂ + P H₂

P tot = 2.31 atm + 3.75 atm

P tot = 6.06 atm

The mole fraction of O₂ (X O₂):

P O₂ = X O₂ x P tot

X O₂ = P O₂ / P tot

X O₂ = 2.31 /6.06

X O₂ = 0.381

The mole fraction of oxygen gas in the given mixture of oxygen and hydrogen gas is 0.381.

How do we calculate mole fraction?

If the details is present in terms of partial pressure then by using the below equation, we can calculate the mole fraction as:

p = (x)(P), where

p = partial pressure

P = total pressure

x = mole fraction

Total pressure of the mixture will be calculated by adding the partial pressure of oxygen and hydrogen gases as:

P = 2.31 + 3.75 = 6.06 atm

Now mole fraction of oxygen will be calculated as:

x = 2.31 / 6.06 = 0.381

Hence mole fraction of oxygen is 0.381.

How much volume (in cm3) is gained by a person who gains 12.3 lb of pure fat?

Answers

Answer:

So we are given with the mass while we are asked for the amount of volume. So this means, we must need an information on the density. From literature, the density of human fat is 0.918 g/cm³. Convert grams to lb by the conversion that 1,000 g = 2.2 lbs.

Density = 0.918 g/cm³ * (2.2 lbs/1,000 g) = 0.0020196 lb/cm³

Volume = Mass/Density = 12.2 lb / 0.0020196 lb/cm³

Volume = 6,040.8 cm³

A. A student was given an unknown sample of a pure metal to identify. Its mass was 116
g. He determined that 511 J of energy raised the temperature of the sample from 21.6°C
to 40.5°C. Based on his measurements, what kind of metal was the sample? (4 points)

Answers

Answer:

Silver

Explanation:

Given parameters:

Mass = 116g

Energy  = 511J

Initial temperature  = 21.6°C

Final temperature  = 40.5°C

Unknown:

Specific heat capacity and the type of metal = ?

Solution:

To solve this problem, we need to find the specific heat capacity of the metal given,

         H  = m x c x Ф  

H is the energy

m is the mass

c is the specific heat capacity

Ф is the change in temperature

        511  = 116 x c x (40.5 - 21.6)

         511  = 2192.4c

           c  = 0.233J/g°C

The specific heat capacity of silver is similar to this.

Answer:

READ THE EXPLAINATION

Explanation:

It says show your work.

40.5°C – 21.6°C = 18.9°C

So, the metal was raised 18.9 deg Celsius.  

It took 511 J of energy to raise the metal 18.9 deg Celsius.

511/ 18.9 = 27.03  

It takes 27.03 J to raise 116 g of the metal 1 degree.    

27.03/116 = .233

It takes .233 J to raise 1 gram of the metal 1 degree.

Therefore, the specific heat capacity of the metal is .233 J

According to the Specific heat values table, Silver has a specific heat capacity of .233.

The metal is silver.

K = [Ca²⁺] [OH¯]² / [Ca(OH)₂]

2. Iron reacts slowly with hydrochloric acid to produce iron (II) chloride and hydrogen gas.

What mass of hydrogen chloride is required to react with 3.56 g of Iron?

Answers

Mass of Hydrogen chloride : 4.672 g

Further explanation

Given

Reaction

Fe + 2HCl ⇒ FeCl2 + H2

3.56 g of Iron

Required

mass of Hydrogen chloride

Solution

mol of Iron (Ar = 56 g/mol) :

mol = mass : Ar

mol = 3.56 : 56

mol = 0.064

mol HCl from the equation :

= 2/1 x mol Fe

= 2/1 x 0.064

= 0.128

Mass HCl :

=mol x MW HCl

= 0.128 x 36.5

Of the following substances, only _____ has London dispersion forces as its only intermolecular force.

A) CH3OH B) NH3 C) H2S D) CH4 E) HCl

Explain the reasoning. (PLEASE EXPLAIN!!!!!!)

Answers

Answer:

A

Explanation:

a) C6H14, C8H18 – London-dispersion force

Since both substances have the same intermolecular force, the substances with the

larger molecular mass with have the higher boiling point. In this case, C8H18 will

have the higher boiling point.

b) C3H8 – London-dispersion force

CH3OCH3 –Dipole-dipole

The higher boiling point belongs to CH3OCH3 because is has the stronger

intermolecular force, dipole-dipole interaction.

c) CH3OH – Hydrogen bonding

CH3SH – Dipole-dipole interaction

Hydrogen bonding is the strongest intermolecular force, so CH3OH will have the

higher boiling point.

d) NH2NH2 – Hydrogen bonding

CH3CH3 – London-dispersion force

Hydrogen bonding is the strongest intermolecular force, so NH2NH2 will have the

higher boiling point.

The only intermolecular interaction present in the methane molecule is London dispersion forces.

The following points can be considered:

The electronegativity of the carbon and hydrogen is closer in values. Therefore the carbon to hydrogen bond in the methane molecule is not polar. The only intermolecular interaction present in the molecule is a weak London dispersion force.Methanol is having dipole-dipole interactions, hydrogen bonding interactions. Ammonia is a polar molecule and hence there are dipole-dipole interactions. Hydrogen sulphide possesses a change in the electronegativity of sulphur and hydrogen. So the molecule is polar in nature. The HCl molecule is polar in nature, possess dipole-dipole interactions.

Therefore, the correct answer is D)CH4 that is methane.
