Fe2O3+2Al ~2Fe+Al2O3

Chemistry
1 answer:
wolverine [178]4 years ago
4 0
<span>I presume that you mean 15.0 g of iron(III) oxide

moles Fe2O3 = 15.0 g /159.694 g/mol= 0.0939

the ratio between Fe2O3 and Al2O3 is 1 : 1

moles Al2O3 = 0.0939

mass Al2O3 = 0.0939 mol x 101.963 g/mol= 9.57 g </span>

What happens to the equilibrium between NO2(g) and N2O4(g) in inert argon when the volume is increased and additional argon is a
Korvikt [17]

Answer:

Equilibrium will be shifted towards NO2 as it has the most of the moles in the reaction.

Explanation:

Hello there!

In this case, according to the equilibrium reaction between NO2 and N2O4, we are able to write:

2NO_2(g)\rightleftharpoons N_2O_4(g)

We can recall the LeCha-telier's principle to realize that the increase of volume promotes the formation of the most of the moles, this is for NO2 because it has a coefficient of 2 and N2O4 a coefficient of 1; in such a way, we infer that the addition of argon, to increase the pressure, will shift the equilibrium towards NO2.

Regards!

The decomposition of N_2O_5(g) following 1st order kinetics. N_2O_5(g) to N_2O_4(g) + ½ O_2(g) If 2.56 mg of N_2O_5 is initially
Crank

Answer: The rate constant is 0.334s^{-1}

Explanation ;

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  = ?

t = age of sample  = 4.26 min

a =  initial amount of the reactant  = 2.56 mg

a - x = amount left after decay process  = 2.50 mg

Now put all the given values in above equation to calculate the rate constant ,we get

4.26=\frac{2.303}{k}\log\frac{2.56}{2.50}

k=\frac{2.303}{4.26}\log\frac{2.56}{2.50}

k=5.57\times 10^{-3}min^{-1}=5.57\times 10^{-3}\times 60s^{-1}=0.334s^{-1}

Thus rate constant is [tex]0.334s^{-1}

EXPLAIN the steps you would take to complete this conversion problem.
Alex

Answer:

Next, the lb will be canceled at 2.2 lb and the kg would be canceled at 1 kg. You cross, multiply, then. 46 x 1 x 1000 is 46000, only moving to the decimal point. 1 x 2.2 x 1 will stay the same, so you'd have 46000 over 2.2.

5. Balance the equation and state the limiting reagent in the following reaction:
mr Goodwill [35]

Answer:

5. 2 Al  3 Cl2 and 2 AlCl3

Cl2 is limiting

(It has the highest coefficients, but that's not always true. If they give you the number of grams for each make sure to work the math out)

6. C

(As the pressure increases there is less volume for the molecules to move around, therefore the molecules will be closer together, allowing for more collisions.)

7.  b

(if the temperature is increases so will the rate of the reaction. The increase in temperature will allow for the molecules to move at a faster rate, allowing for more collisions (reactions) between them.

8. d

(dynamic equilibrium is the state at which the reaction is consistently moving, there fore the amounts should remain the same)

9. A

(a catalyst will lower the the pathway of activation energy because it's meant to speed up a reaction)

bro youre on your own after this, im tired
