Consider the reaction. Upper n subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3
umka2103 [35]

The equilibrium constant of the reaction is 0.0030.

The equation of the reaction is given as;

N2(g) + 3H2(g) ⇆ 2NH3 (g)

We have the following information at equilibrium;

[NH3] = 0.105 M

[N2] = 1.1 M

[H2] = 1.50 M

Hence, we can calculate the equilibrium constant using the relation;

K = [NH3]^2/ [N2]  [H2]^3

Substituting values;

K = [0.105]^2/[ 1.1] [1.50]^3

K =0.011025 /3.7125

K= 0.0030

You can spend at most $60 on beads. A bag containing red beads costs $2 per bag. A bag containing blue beads costs $3 per bag. Y
nexus9112 [7]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of blue beads
 y: number of red beads
 We now write the inequations system:
 3x + 2y  \leq  60

x\ \textgreater \  y
 Answer:
 a system of linear inequations that represents the situation is:
 3x + 2y \leq 60 x\ \textgreater \ y

Priya, and Jibran take 1 hour and 10 minutes working together to deliver all newspapers on their route. Priya, when working alon
Evgen [1.6K]

Answer:

Priya takes 32 minutes and 30 seconds to complete the route and Jibran takes 37 minutes and 30 seconds to complete the route.

Step-by-step explanation:

We have that Priya (P) and Jibran (J) take 1 h + 10 min working together:

P + J = 60min + 10min = 70 min    (1)

Also, Priya can finish the delivery 5 minutes faster than Jibran:

P = J - 5    (2)  

By entering equation (2) into (1) we have:

(J - 5) + J = 70 min

2J = 75 min

J = 37.5 min = 37 min + 30 s

Hence, Jibran takes 37 minutes and 30 seconds to complete the route.

Now, by entering J into equation (2):

P = 37 min + 30 s - 5 min = 32 min + 30s

Therefore, Priya takes 32 minutes and 30 seconds to complete the route.

I hope it helps you!

One platy requires 5 liters of water to live healthfully. What is the maximum number of healthy platies that can be kept in a re
vagabundo [1.1K]

Answer:

  7

Step-by-step explanation:

I like to work liter volume problems in terms of decimeters. 1 dm = 10 cm, and 1 dm³ = 1 L, so the tank is 3 dm by 4 dm by 3 dm = 3×4×3 dm³ = 36 L.

  36 liters will support 36/5 = 7.2 platies.

7 platies can be kept in the aquarium.
