PLEASE HELP!! The diagram shows to sound Waves as transverse waves sound waves are sometimes drawn as transverse ways to make certain properties easier to compare. What can you tell from comparing these waves. A. wave A is lounder B. wave B has a higher pitch C. Wave A is softer D. Wave B has a lower pitch

h let me think

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
