The efficiency of the machine which has an energy loss of 10% is 90%

<h3>What is efficiency? </h3>

This can be defined as the capacity to achieve a given task with little or no waste. Mathematically, it can be expressed as

Efficiency = (output / input) × 100

<h3>How to determine the efficiency </h3>

We shall assume the following:

  • Input = 100 J
  • Output = 100 – 10 = 90 J
  • Efficiency =?

Efficiency = (output / input) × 100

Efficiency = (90 / 100) × 100

Efficiency = 90%

Hi!! please help :( lots of points !
andreev551 [17]

Answer:

<u><em>Structure:</em></u>

<em>Differences-  </em>A polymer is a collection of a large number of molecules whereas a monomer is a single molecule.

A monomer is a single molecule, which has the ability to chemically bond with other monomers in a long chain. A polymer is a chain that is made when monomers bind with other monomers.

<em>Similarities-</em>  They are both molecules

<u><em>Properties:</em></u>

<em> Differences- </em>Monomers have polyfunctionality, which is the capacity to form chemical bonds to at least two other monomer molecules. Polymers are chemically unreactive, solids at room temperature, malleable, tough, and are electrical insulators.

<em>Similarities- </em>They both makeup larger forms of matter.

<u><em>Intermolecular Forces</em></u>

<em>Differences: </em>Polymers are held together by covalent bonds, hydrogen bonds, and dispersion bonds. Monomers are <u><em>only</em></u> held together by hydrogen bonds.

<em>Similarities: </em>They can both be bonded together by hydrogen bonds.

22.00 g of CO2 has a volume of 50.00 L and a pressure of 0.8210 atm. What must be the
creativ13 [48]

Answer:

T = 9.875K

Explanation:

The ideal gas Law is PV = nRT.

P = Pressure

V = Volume

n = amount of substance

R =  8.314 J/(K. mol)

T = Temperature in Kelvin

22g CO2

CO2 Molar Mass = 44g/mol

C = 12g/mol

O = 16g/mol

P = 0.8210atm

V = 50L

PV = nRT

0.8210 x 50 = 8.314 x 0.5 x T

41.05 =  4.157T

T = 41.05/4.157

T = 9.875K
