Predict the sign of ΔSsys for each process: (b) A solid explosive converts to a gas.
Goryan [66]

The sign of ΔSsys for a solid explosive converts to a gas is positive.

The term used for the measurement of randomness and disorderliness in a system is known as Entropy (S). ΔS calculates the change in entropy and it is positive when entropy increase and negative when entropy decreases.

Entropy increases when heat is added to the system. Addition of heat increases the randomness of the molecules and hence the entropy increases.

When a solid explosive converts to a gas the randomness increases. Explosive causes heat and the solid is converted into gas. The randomness of molecules is maximum in gases thus the entropy increases. The sign of ΔS is positive for this process.

Tom [10]

Answer:

The last one, to swim

Explanation:

The function of cilia and flagella move liquid past the surface of the cell. For single cells, such as sperm, this enables them to swim. For cells anchored in a tissue, like the epithelial cells lining our air passages, this moves liquid over the surface of the cell (e.g., driving particle-laden mucus toward the throat).

Inessa05 [86]

Answer:

H2SO4

Explanation:

An electrolyte is a chemical compound that conducts electricity by changing into ions when melted or dissolved into a solution. An example of an electrolyte is sodium chloride.

Strong acids such as sulfuric acid (H2SO4), and strong bases such as potassium hydroxide (KOH), and sodium hydroxide (NaOH) are frequently used as electrolytes due to their strong conducting abilities.
