Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
Answer:
The density of the block is 2.827 grams/ cubic inch
Explanation:
The density of the block can be obtained by dividing the given mass of the block by its volume.
Density = mass / volume
The mass of the block given is 435.5 grams
The volume of the block can be obtained by using the formula:
Volume = Length X breadth X height
Volume = 3.5 X 8 X 5.5 = 154
There fore the density will be 435.5 / 154 = 2.827 grams/ cubic inch
