A solution was formed by combining 25.0 g of solid A with 60.0 mL of distilled water, with the water initially at 21.4oC. The final temperature of the solution was 25.3oC Calculate the heat released as the solid dissolved, qsoln, assuming no heat loss to the calorimeter.

Consider the equilibrium system: 2icl(s) ⇄ i2(s) + cl2(g) which of the following changes will increase the total amount of of cl2 that can be produced? all of the listed answers are correct decreasing the volume of the container removing the cl2 as it is formed adding more icl(s) removing some of the i2(s)

Some animals that try to adapt to climate changes eventually die due to starvation, as climate change alters the web.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
