A car manufacturer needs to assemble the maximum number of cars using the following equation: 1 body frame + 4 wheels + 2 headli
larisa [96]

The wheels will be completely used up and  it is the limiting reactant in this case.

<h3>What is a limiting reactant?</h3>

The limiting reactant is the reactant that is completely used up in a reaction, and thus determines when the reaction stops.

  • 60 breaks will be used for 30 engines and 30 body frame
  • 80 wheels will be used for 20 engines and 20 body frame
  • 64 headlights will be used for 32 engines and 32 body frame

The wheels will be completely used up and  it is the limiting reactant in this case.

3- Gas in a piston has a volume of 6.6 L, a temperature of 115 °C. If the final
Maru [420]

Answer:

d- 7.58 L

Explanation:

According to Charles's law, the temperature in Kelvin is proportional to the volume of a dry gas when the pressure is constant.

Mathematically, V1/T1 = V2/ T2

V1= initial volume= 6.6 L

T1= Initial temperature= 115 °C= (115 °C +273)=388K

V2= final volume

T2= final temperature= 173 °C= ( 173 °C+ 273)= 446K

Substitute the values,

V2=( V1 × T2)/ T1

= (6.6×446)/388

= 2943.6/388

= 7.6L
