Answer : The volume of gas will be, 113.5 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 60 atm
= final pressure of gas = 30 atm
= initial volume of gas = 29 L
= final volume of gas = ?
= initial temperature of gas = 115 K
= final temperature of gas = 225 K
Now put all the given values in the above equation, we get:
Therefore, the volume of gas will be, 113.5 L
Given the length of each side of a cube and its mass, the density can be obtained which can then help identify the type of material it's made of. This is because density is a unique and intrinsic property of materials. For this problem, the density is determined to be 10g/cm^3. Looking at a table of densities, the metal is most likely actinium, which has an exact density of 10 g/cm^3.
Alias: Mercuric Hydrogen Carbonate; Mercury(II) Bicarbonate
Formula: Hg(HCO3)2
Molar Mass: 322.6237
The answer to your question is the option D, it moves crust plates around
Number of atoms = moles of magnesium x 6.02x10^23
= 5x6.02x10^23
= 3.01x10^24 atoms.
Hope this helps!
