A chemical change is something you can't see and a physical change is something you can see.

With a physical change you can actually see it change like ice turning into water, then with a chemical change you can't see it change, although within the molecules themselves they change which makes that possible.


Hope this helps!

In order for matter or energy to be conserved, one must have a ____ system.
Leya [2.2K]
Closed system.  If the system is not closed, matter or energy can escape from the system.  an example of this is if you react magnesium and hydrochloric acid in a open system.  The H₂ gas is going to escape making it look like some of the mass disappeared .  in that same reaction some in an open system will also loose heat to the surrounding which will make it look like less heat was produced.

At the start of a reaction, there are 0.0249 mol N2,
gladu [14]

Answer:

Explanation:

The reaction is given as:

N_{2(g)} + 3H_{2(g)} \to 2NH_{3(g)}

The reaction quotient is:

Q_C = \dfrac{[NH_3]^2}{[N_2][H_2]^3}

From the given information:

TO find each entity in the reaction quotient, we have:

[NH_3] = \dfrac{6.42 \times 10^{-4}}{3.5}\\ \\ NH_3 = 1.834 \times 10^{-4}

[N_2] = \dfrac{0.024 }{3.5}

[N_2] = 0.006857

[H_2] =\dfrac{3.21 \times 10^{-2}}{3.5}

[H_2] = 9.17 \times 10^{-3}

∴

Q_c= \dfrac{(1.834 \times 10^{-4})^2}{(0.0711)\times (9.17\times 10^{-3})^3} \\ \\ Q_c = 0.6135

However; given that:

K_c = 1.2

By relating Q_c \ \ and  \ \ K_c, we will realize that Q_c \ \ <  \ \ K_c

The reaction is said that it is not at equilibrium and for it to be at equilibrium, then the reaction needs to proceed in the forward direction.
