Answer:

V = 4/3 * 3.1416 * (37x10-10)3

V = 2.12x10-25 cm3

d = m/V

d = 1.67x10-24 / 2.12x10-25 = 7.87 g/cm3

The difference in temperature, let's convert F to ºC:

ºC = -80-32/1.8 = -62.22 ºC

dT = -92.6 + 62.2 = -30.4 ºC

cestrela7 [59]

Answer:

Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.

Explanation:

The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.

At this stage the change in concentration of reactants becomes equal to the change in concentration of products.

The reaction will never cease.

That is the reason chemical equilibrium is called dynamic equilibrium.

So, forward and backward reactions will be taking place continuously at equal rates.

What is the identity of a sample that has a mass of 25.0 g and a volume of 2.38 cm3?
Snezhnost [94]
One of the defining features of an element is it's density. Calculate that and verify which substance this would be. 

p=m/v 
p=25g/2.38 cm^3 
p=10.50 g/cm^3 

Density of Silver is 10.5 g/cm^3 

Hope I helped :)
