13.26 g has 4 significant figures
The solution would be like
this for this specific problem:
<span>Moles of carbon = 58.8 /
12 = 4.9 </span><span><span>Moles of hydrogen = 9.8 / 1 = 9.8 </span><span>Moles of oxugen = 31.4 / 16 m= 1.96 </span><span>Ratio 4.9 / 1.96 = 2.5 9.8 / 1.96 = 5.0 1.96 / 1.96 = 1 </span></span>
To know what happens with the concentration, we must calcute the limit of the function where t → ∞. The limit is the value that the function approach when t intend to a value. So:
Dividing both for "t"
The limit of 1/t when t intend to infity is 0, which is demonstrated in the graph below, so:
The concentration will approach 20 g/L.
When a mass of magnesium is burned it increases in mass due to the oxygen combining with the molecules. The amount of mass increase is proportional and predictable if you know the mass of the starting magnesium.
B. touch to transfer
hope this Helps.
