Answer:
50g
Explanation:
At the end of the burning process, the mass of the jar and smoke should be 50g after the candle burning is done.
In most systems, the law of conservation of matter finds expression. According to this law "matter is neither created nor destroyed but atoms are rearranged".
In this kind of system, no matter is allowed to escaped and the starting mass of the reactants compared to that of the product will be the same.
You could write about a fear you may have had as a child, eg. the dark, or underneath the bed, etc...
Atomic weight of fluorine is 19 g/mol.
We know that, 1 mol (19 g) of Fluorine will have Avagadro number (6.022 X 10^23) of Fluorine atoms
Thus, we have 6.022 X 10^23 atoms of F ≡ 19 g of F
Therefore, 1.35 x10^23 atoms of F ≡ 4.259 g of F
Now, 19 g of Fluorine ≡ 1 mole
∴, 4.259 g of Fluorine ≡ 0.224 mole
Answer: 0.224 <span>moles are in 1.35 x10^23 representative particles of Fluorine</span>
The periodic table- find the molecular weight of water (g/mol), and divide the mass of water in g by the molecular weight to give moles of water
This is easy the answer is b forming a mixture your welcome hope this helps and good luck
