Mercury is a metal at liquid at room temperature, with a density of 13.5 g/cm3, what will happen if a small cube of silver is placed in a container of liquid mercury? Please help me
I need the answer quick

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

What stress will shift the following equilibrium system to the left? n2(g) + 3h2(g) ⇌ 2nh3(g) adding more n2(g) adding more nh3(g) increasing the pressure of the system reducing the volume of the container

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system
