Answer:
The three statements are true
Explanation:
For the reaction:
I₂O₅(s) + 5CO(g) → I₂(s) + 5CO₂(g)
State oxidation of iodine in I₂O₅ is:
5 O²⁻ = 10⁻
As you have 2 I and the molecule has no charge, <em>oxidation state of I is +5</em>.
The carbon in CO has an oxidation state of +2 and in CO₂ is +4. That means <em>the carbon is oxidized</em>
<em />
An oxidizing agent is a substance that produce the oxidation of the agent that reacts with this one. CO is oxidized because of I₂O₅ is producing its oxidation being <em>the oxidizing agent</em>
<em></em>
Thus,<em> the three statements are true</em>.
Answer: The specific heat of the unknown metal is 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed=
Joules
m= mass of substance = 86.8 g
c = specific heat capacity = ?
Initial temperature of the water = 
Final temperature of the water = 
Change in temperature ,
Putting in the values, we get:
The specific heat of the unknown metal is
The answer is C. The answer is C because if u increase the surface area, the more reactants u will get. and if u get more The reactants will move faster. Hoped that Helped!:-)
Answer:Write and balance the equation
4Fe + 3O2 -> 2Fe2O3
0.32 mol Fe x 2 mol Fe2O3 / 4 mol Fe =
0.16 mol of Fe2O3
