Answer:
Explanation:
Hello,
In this case, the increase in the temperature involves the addition of heat that is defined in terms of mass, heat capacity and temperature:
In this case, the heat capacity of iron is 0.450 J/(g*K), thus the heat results:
In such a way, since the temperature is increased heat is added, that is why it is positive.
Best regards.

Answer: Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as
<u>Chiral Molecules</u>.
Explanation: Chiral molecules have stereogenic centers. When plane polarized light is fall on these compounds they rotate the light either in clockwise or anti clockwise direction. The mirror images of chiral moleculecules are non-superimposable. Below few examples for molecules containing chiral centers are given.</span>
Answer:
0.055g/mL
Explanation:
Data obtained from the question include:
Molar Mass of the gass sample = 71g/mol
Volume of the gas sample = 1300 mL
Density =?
The density of a substance is simply mass per unit volume. It is represented mathematically as:
Density = Mass /volume.
With the above equation, we can easily obtain the density of sample of gas as illustrated below:
Density = 71g / 1300 mL
Density = 0.055g/mL
Therefore, the density of the gas sample is 0.055g/mL
