Calculate the work (kJ) done during a reaction in which the internal volume expands from 28 L to 51 L against an outside pressure of 4.9 atm. Calculate the work (kJ) done during a reaction in which the internal volume expands from 28 L to 51 L against an outside pressure of 4.9 atm. 11 kJ -11 kJ -39 kJ 39 kJ 0 kJ; No work is done.

-11 kJ

Explanation:

Step 1: Convert the pressure to Pascal (SI unit)

We will use the relationship 1 atm = 101,325 Pa.

Step 2: Convert the volumes to cubic meters (SI unit)

We will use the relationship 1 m³ = 1,000 L.

Step 3: Calculate the work done during the expansion of a gas

We will use the following expression.

Step 4: Convert the work to kiloJoule

We will use the relationship 1 kJ = 1,000 J.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
