The formation of nitrogen dioxide and oxygen,

Chemistry
1 answer:
kvasek [131]3 years ago
7 0

Answer:

The rate of reaction changes by a factor 6.

Explanation:

Given the reaction is first order.

Let us assume the initial concentration of NO is A and the initial concentration of O_3 is B.

So, we can write the rate of the reaction as

R=k[A][B]

Where,

R is the rate of reaction. And k is the rate constant.

Also, the initial concentration of NO has been increased by 0.5, and the initial concentration of  O_3 was increased by factor 4.

So, we have

R'=k[1.5A][4B]\\R'=6k[A][B]\\R'=6R

We can see the rate of reaction changes by a factor 6.

Ammonium nitrate is an ingredient in cold packs used by sports trainers for injured athletes. Calculate the change in temperatur
Ronch [10]

Answer:

See explanation

Explanation:

First, we need to use the correct expression:

Q = m*Cp*ΔT  (1)

Q = n*ΔH  (2)

These are the 2 expressions to calculate heat or energy.

Now, we want to know the change of temperature of the nitrate in water after being added, so with the innitial data of nitrate, we can calculate heat using the second expression. First, we need to calculate moles with the molecular mass:

n = m/MM

n = 42/80.1 = 0.52 moles

With these moles, we can calculate heat with the ΔH of this reaction:

Q = 0.52 * 25.7 = 13.364 kJ or 13,364 J

However, this heat as is being absorbed, the value would be negative.

Now that we have heat, we can use expression (1) and plug these values to solve for ΔT, but before, we need to know the total mass of the solution (water + nitrate)

m = 250 + 42 = 292 g

now, solving for ΔT:

-13,364 = 292 * 4.18 * ΔT

ΔT = -13,363 / (292 * 4.18)

ΔT = -10.95 °C

How are distillation and reverse osmosis alike?
Andrei [34K]
I'm having trouble with this one. At the very least, they both purify water. If I'm not mistaken, distillation is part of the process of purifying water.
Really sorry, I hope I helped at least a little! If you have any other questions I might be able to answer better, let me know..
