Answer:
The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules

Answer:
Explanation: Because electrons are delocalized around positively charged nuclei, metallic bonding explains many properties of metals. ... Further, because the electrons are free to move away from each other, working a metal doesn't force together like-charged ions, which could fracture a crystal through the strong repulsion.
Answer:
The unknown substance is rhodium.
Explanation:
Heat lost by hot substance will be equal to heat gained by the water
Mass of substance=
Specific heat capacity of substance=
Initial temperature of the substance =
Final temperature of substance=
Mass of water = M
Volume of water ,V= 35 ml
Density of water = d = 1.00 g/mL
Mass of water=
Specific heat capacity of water=
Initial temperature of the water =
Final temperature of water =
On substituting all values:
we get,
The value of heat capacity of the substance is equal to that of rhodium metal.Hence, the unknown substance is rhodium.
