The decomposition of ammonia to nitrogen and hydrogen on a tungsten filament at 800°C is independent of the concentration of amm
finlep [7]

Answer:

Order zero

Explanation:

Let's consider the decomposition of ammonia to nitrogen and hydrogen on a tungsten filament at 800°C.

2 NH₃(g) → N₂(g) + 3 H₂(g)

The generic rate law is:

rate = k × [NH₃]ⁿ

where,

rate: reaction rate

k: rate constant

n: reaction order

When n = 0, we get:

rate = k × [NH₃]⁰ = k

As we can see, when the reaction order with respect to ammonia is zero, the reaction rate is independent of the concentration of ammonia.

ser-zykov [4K]

Answer: Gravity.

Explanation:

Earth and other objects would have fly off into space in a straight line if there would have been no gravity in between objects.

The gravity can be defined as the force between two objects in space which keeps two objects together in the space.

It is also responsible for holding the objects in space, making them move on their orbits, not allowing the heavenly bodies to crash.

So, there would be no gravity the objects will fall off in a straight line and none of the objects would be at its specified position.

You need a 35% alcohol solution. On hand, you have a 280 mL of a 30% alcohol mixture. You also have 75% alcohol mixture. How muc
Marina CMI [18]

Answer:

35 mL

Explanation:

Let the amount of 75% mixture needed be A.

The amount of each solution with their respective concentration to be added together can be expressed as:

0.75A + 0.3(280)...............eqn 1

The addition of the two solution must merge with the expected concentration and this can be expressed as:

0.35(A + 280).............eqn 2

Eqn 1 must be equal to eqn 2, hence:

0.75A + 0.3(280) = 0.35(A + 280)

Solve for A.

0.75A + 84 = 0.35A + 98

0.40A = 14

A = 35

Hence, 35 mL of the 75% mixture will be needed.
