Once the water evaporates, you will start to see the minerals that were present in the water before it changed state. If the water was from the ocean, you will see salt crystals in the evaporated water. If the water was fresh, you may see other minerals typically found in fresh water.

Consider the following system at equilibrium where H° = 16.1 kJ, and Kc = 6.50×10-3, at 298 K. 2NOBr(g) 2NO(g) + Br2(g)If the VO

Answer:

1) The value of Kc : (C.) remains the same

2) The value of Qc : (A.) is greater than Kc

3) The reaction must : (B.) run in the reverse direction to reestablish equilibrium.

4) The number of moles of Br2 will : (B.) decrease

Explanation:

Value of concentration equilibrium constant Kc depends only on temperature. Since temperature remains constant, therefore, Kc remains constant.  Decrease in volume means increase in pressure. Increase in pressure favors the side with less gaseous species.  Hence, increase in pressure will favor the reverse reaction towards reactants.

Answer:

K=1.7x10^{-3}

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve this problem by firstly setting up the equilibrium expression for the given reaction, in agreement to the law of mass action:

K=\frac{[NO]^2}{[N_2][O_2]}

Next, we plug in the given concentrations on the data table to obtain:

K=\frac{(0.034)^2}{(0.69)(0.98)}\\\\K=1.7x10^{-3}

Regards!

Compare the charges and masses of<br> protons, neutrons, and electrons.
lapo4ka [179]

Answer:

Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
