1 mol Au ---------------- 196.9665 g
0.150 mol Au ----------- ?
0.150 x 196.9665 / 1
= 29.54 g
hope this helps!
Answer:
Refractive index
Heat capacity
Density
Explanation:
Properties that are used to identify materials are called intensive properties. These intensive properties are characteristic of the material and does not depend on the amount of material present.
Thus, if i want to identify whether the three bars are made of the same metal, i can look out for the following properties;
Refractive index
Heat capacity
Density
These properties are intensive properties thus they can be used to identify an unknown substance.
Answer:
I Would bc it's the better opportunity
Answer:
Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F).
Answer:
The gas temperature increases.
Explanation:
The type of process is an ISOCHORIC process in which the volume is constant. The work done by the system is zero.
The gas will only gain internal energy from the heat energy transferred to the system externally.
The pressure also increases in this type of process.
