Consider the reaction I2O5(g) 5 CO(g) -------> 5 CO2(g) I2(g) a) 80.0 grams of iodine(V) oxide, I2O5, reacts with 28.0 grams
Allisa [31]

Answer:

Maximum mass of I_2 produces=50.8g;

Explanation:

Firstly balance the chemical reaction,

I_2 O_5+5CO=5CO_2+I_2

Molecular weight of I_2 O_5=334g/mole;  

Molecular weight of CO =28g/mole;

Number of mole of I_2 O_5 given=80g/(334g/mole)=0.239mole;

Number of mole of CO given=28g/(28g/mole)=1 mole  

Moles are:

Number of mole of I_2 O_5=0.239

Number of mole of CO=1;

From the balanced equation,

1 mole of I_2 O_5 reacts with 5 moles of CO;

Hence;

0.239 mole of I_2 O_5  will react with 5*0.239 moles of CO means

Moles of CO that reacts with I_2 O_5  =1.2 mole but we have given 1 mole therefore

I_2 O_5 Will be excess reagent and CO will be the limitting reagent  

And mass of product depends on limiting reagent i.e. mass of CO.

5 mole of CO produces 1 moleI_2 of I_2;

1 mole of CO  produces 1/5 mole of I_2;

Maximum mass of I_2  produces=mole*molecular weight;

Molecular weight of I_2=254g/mole;

Maximum mass of   produces I_2= (1/5)*254=50.8g;

Maximum mass of I_2 produces=50.8g;

Kinetic energy and gravitational potential energy are both forms of which type
scoundrel [369]

Answer:

<em>C. Potential energy</em>

Explanation:

Kinetic energy and gravitational potential energy are both forms of potential energy. Potential energy is stored energy, when an object is not in motion it has stored energy. When an object is an motion it has kinetic energy. An object posses gravitational potential energy when it is above or below the zero height.
