From the equation above the reacting ratio of KClO3 to O2 is 2:3 therefore the number of moles of oxygen produced is ( 4 x3)/2 = 6 moles since four moles of KClO3 was consumed
mass=relative formula mass x number of moles
That is 32g/mol x 6 moles =192grams
Answer:
Chloroform= limiting reactant
0.209mol of CCl4 is formed
And 32.186g of CCl4 is formed
Explanation:
The equation of reaction
CHCl3 + Cl2= CCl4 + HCl
From the equation 1 mol of
CHCl3 reacts with 1mol Cl2 to yield 1mol of CCl4
From the question
25g of CHCl3 really with Cl2
Molar mass of CHCl3= 119.5
Molar mass of Cl2 = 71
Hence moles of CHCl3= 25/119.5 = 0.209mol
Moles of Cl2 = 25/71 = 0.352mol
Hence CHCl3 is the limiting reactant
Since 1 mole of CHCl3 gave 1mol of CCl4
It implies that 0.209moles of CHCl3 will also give 0.209mol of CCl4
Mass of CCl4 formed = moles× molar mass= 0.209×154= 32.186g
Answer:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Explanation:
To answer this question, we'll need the molar masses of nickel and vanadium:
Molar mass of nickel: 58.693g/mol
Molar mass of vanadium: 50.941g/mol
These values represent the mass of one mole of the element. A mole is the weight of Avogadro's number of atoms of an element (6.02 x 10^23 atoms).
We are given 58.693g of nickel, which is equivalent to one mole of nickel. Therefore, you will get the same number of atoms from one mole of vanadium, or 50.941g of vanadium.
Depending on the testing process being used, it may affect the object by making it shape differently, scratch, it or sometimes do absolutely nothing. hope this helps:)
