Answer:
C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.
The unbalanced reaction:
I₂ + O₂ -----> I₄O₉
<u>Reactants</u>: 2 iodine, 2 oxygen
<u>Products</u>: 4 iodine, 9 oxygen
The balanced equation:
4 I₂ + 9 O₂ -----> 2 I₄O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
Any elements in the same periodic group as oxygen such as sulfur, as elements are grouped together through similar properties
The amount of energy required to remove the most loosely bound electron in1 mole of an atom in its neutral gaseous state. Atomic radius is smaller, great nuclear charge (pulling power of protons on less electrons)
Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
