Answer:

\boxed {\boxed {\sf 1058.3 \ L}}

Explanation:

We are asked to find the new volume of a gas after a change in temperature. We will use Charles's Law, which states the volume of a gas is directly proportional to the temperature. The formula for this law is:

\frac {V_1}{T_1}= \frac{V_2}{T_2}

The gas was heated to 150 degrees Celsius and had a volume of 1587.4 liters.

\frac {1587.4 \ L }{150 \textdegree C} = \frac {V_2}{T_2}

The temperature was 100 degrees Celsius, but the volume is unknown.

\frac {1587.4 \ L }{150 \textdegree C} = \frac {V_2}{100 \textdegree C}

We are solving for the volume at 100 degrees Celsius, so we must isolate the variable V₂. It is being divided by 100°C and the inverse of division is multiplication. Multiply both sides of the equation by 100°C.

100 \textdegree C *\frac {1587.4 \ L }{150 \textdegree C} = \frac {V_2}{100 \textdegree C} * 100 \textdegree C

100 \textdegree C *\frac {1587.4 \ L }{150 \textdegree C} = V_2

The units of degrees Celsius cancel.

100  *\frac {1587.4 \ L }{150 } = V_2

100 *10.58266667  \ L = V_2

1058.266667 \ L = V_2

The original measurement of volume has 5 significant figures, so our answer must have the same. For the number we calculated, that is the tenth place. The 6 in the hundredth place to the right tells us to round to 2 up to a 3.

1058.3 \ L = V_2

The volume of the gas at 100 degrees Celsius is approximately <u>1058.3 liters.</u>

Describe how the molecular structures of alkenes and alkynes differ from the structure of alkanes
evablogger [386]

Alkanes are saturated hydrocarbon that contains only single bonds, whereas Alkenes and Alkynes are unsaturated hydrocarbons which contain one or more double bond and triple bonds.

<u>Explanation:</u>

  • A saturated hydrocarbon with an only single bond is called alkanes. Ethane consisting of two carbon atoms that are bonded with a single bond and six hydrogen atoms sharing the other valence electron of carbon atoms. The molecular structure of alkane is CnH2n+2.
  • An unsaturated hydrocarbon with a two bond is called alkenes. Ethene consisting of two carbon atoms double-bonded to each other. The molecular structure of alkene is CnH2n.
  • An unsaturated hydrocarbon with a triple bond is called as alkynes. It involves sharing three pairs of electrons. The molecular structure of alkyne is CnH2n-2.

Forces that change an object motion by touching the object are _______ forces
strojnjashka [21]

Forces are pushes and pulls that may change the motion of an object. Balanced forces result in an object remaining at rest or moving at a constant speed. Unbalanced forces result in the acceleration of an object. An object's motion depends on how it changes position.
