Answer:
The equation is Fe₂O₃ + CO ⇒ Fe + CO₂.
The balanced reaction equation is Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂.
Explanation:
First, we have to write our equation. It's actually pretty straightforward - first we look for our reactants (looks like it's Fe₂O₃ and CO), then we look for our products (Fe and CO₂). Then, we have to balance it so that both sides have the same number of both element.
Currently, we have the equation Fe₂O₃ + CO ⇒ Fe + CO₂. There are 2 Fe atoms, 4 O atoms, and 1 C atom on the left side. There is 1 Fe atom, 2 O atoms, and 1 C atom on the right side.
First thing we can do is give our Fe on the right side a coefficient of 2. This will make it equivalent to the 2 Fe atoms on the left side:
Fe₂O₃ + CO ⇒ 2Fe + CO₂
Next, we need to make sure that we have the same number of C and O atoms on each side. This takes a little bit of thinking, but what we have to do is give CO a coefficient of 3 and CO₂ a coefficient of 3. This gives us 6 O atoms on the left side (when we include the O₃) and 6 O atoms on the right side (since there are 3 O₂ atoms and 3 times 2 is 6). Here's what that looks like:
Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂
And that's how I balanced the equation. It can be confusing, but with enough practice, it will get easier and easier. :)
Percent yield = (Actual Yield/ Theoretical Yield) x 100
Given, Actual Yield of silver = 410 grams
Given, mass of copper = 127 g
Atomic mass of copper = 63.546 amu
Formula: Moles = mass / atomic mass
Moles of copper = 127 g/ 63.546 amu = 1.998 mol
Based on the given balanced chemical reaction, the molar ratio between Cu: Ag is 1:2
So 1.998 mol of copper should yield (2 mol Ag/ 1 mol Cu) x 1.998 mol of Cu = 3.996 mol
Calculated mol of Ag = 3.996 mol
Atomic mass of silver = 107.8682 amu
Mass of silver = moles x atomic mass = 3.996 mol x 107.8682 amu = 431 g
Based on the math, the theoretical yield = 431 g
Percent yield of silver = (410g/431g) x 100 = 95. 13%
The answer is 95. 13%
From among the subatomic particles available, we determine which element is presented by using the number of protons. The 49th element in the periodic table is Indium (In). The chemical symbol is In-62. 62 is the number representing the number of neutrons .
Answer: In-62
