Answer: A reversible reaction is a reaction that takes place in back and front directions. If the reaction were to reach equilibrium, the rate of forward direction would be equal to that of the reverse reaction.

Explanation:

Reversible reactions :

These are the reaction in which reactants reacts to give product and products reacts to give reactants as a product in return.

        A+B\leftrightharpoons C+D

  • In above equation, 'A' and 'B' are reacting together to give 'C' and 'D', as products and vice-versa.
  • When the above reaction reaches equilibrium the rate of forward and backward reaction becomes equal.

If a gold bar is 16,000 g mass and 800 cm^3 volume what is the density?
ki77a [65]

Answer:

<h3>The answer is 20 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 16,000 g

volume = 800 cm³

We have

density =  \frac{16000}{800}  =  \frac{160}{8}  \\

We have the final answer as

<h3>20 g/cm³</h3>

Hope this helps you

Specific gravity is a number representing the ratio of a mineral's weight to the weight of an equal volume of water. TRUE FALSE
777dan777 [17]

Answer: True

Explanation: Specific Gravity of a body, also called its Relative Density, is the ratio of the density of that body to the density of a reference material (usually water).

With the Mathematics done right, it is evident that the specific gravity of a body would be equal to the ratio of mass/weight of the body to the mass/weight of an equal volume of water.

S.G = (Density of body)/(Density of water)

Density of Body = (mass/weight of body)/(volume of body)

Density of water = (mass/weight of water)/(volume of water)

If volume of Body = Volume of water, then,

S.G = (Mass/Weight of body)/(Mass/Weight of equal volume of water)
