I try but I don’t find the answer sorry
While voltage does pose a threat, it's mostly the current that causes damage. There must be voltage available to motivate electrons to flow through a victim. Resistance to current causes (in the case of the victim being human or having flesh) burnt tissues, muscles freezes, and fibrillates hearts.
Answer:
14.29g
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below below:
4Fe + 3O2 —> 2Fe2O3
Next, let us calculate the mass of Fe that reacted and the mass of Fe2O3 produced from the balanced equation. This is shown below:
Molar Mass of Fe = 56g/mol
Mass of Fe from the balanced equation = 4 x 56 = 224g
Molar Mass of Fe2O3 = (56x2) + (16x3) = 112 + 48 = 160g/mol
Mass of Fe2O3 from the balanced equation = 2 x 160 = 320g
From the balanced equation,
224g of Fe produced 320g of Fe2O3.
Therefore, 10g of Fe will produce = (10x320)/224 = 14.29g of Fe2O3
From the calculations made above, 10g iron(Fe) produced 14.29g of iron(iii) oxide (Fe2O3)
