Answer:
Wavelength (λ) – The distance of one complete cycle in the wave. The distance between two consecutive crests and /or troughs. S.I. Unit: metre (m).
In other words:
Wavelength is the distance from crest to crest (or trough to trough).
The answer would be strength. Because the Ph is the measurement of how strong or how high the hydronium ion in a solution

The content that follows is the substance of lecture 14. In this lecture we cover the use of balanced chemical equations to make mole and mass predictions in reaction. Reaction stoichiometry is a fancy way of describing mole relations in a reaction. When we read a balanced equation we relate every compound in the reaction to the others by means of the mole coefficients in the reaction. For example: HCl + NaOH → NaCl + H2O This equation is all 1:1 relationships, 1 mole of NaCl is made for every 1 mole of HCl or NaOH etc. In a previous lecture I introduced the following analogy: What can we do with a balanced equation? A chemical reaction equation is essentially a table of conversion factors that we can use to predict amounts of products that can be made, reactants needed to make a specific amount of product or exact amounts of reactants needed to completely consume another reactant (eg. acid and base neutralization). While the use of the stoichiometry (fancy words for mole relationships in a reaction equation) may seem difficult, it really isn't. Let's use an example that you all can understand first: 1 slice bologna + 2 slices of bread → 1 Sandwich If I asked you how many sandwiches you could make with 12 slices of bread, you would immediately say 6, right? How did you know this? Well, obviously based on the equation, you make 1 sandwich for every 2 slices of bread you have.12 slices bread x 1 sandwich/2 slices bread = 6 sandwiches If I asked you how many slices of bologna and bread you need to create 10 sandwiches, you would immediately say 10 slices of bologna and 20 slices of bread, right? Again the relationship given in the equation tells you how much is needed. 10 sandwiches x 1 slice bologna/1 sandwich = 10 slices bologna and 10 sandwiches x 2 slices bread/1 sandwich = 20 slices bread Finally if I asked you how many sandwiches you could make with 5 slices of bologna and 8 slices of bread? Which of the two sandwich makings would run out first and how much of the excess makings would be left over? Well, the answers are 4 sandwiches could be made and 1 slice of bologna is left over. 5 slices of bologna x 1 sandwich/1 slice bologna = 5 sandwiches 8 slices bread x 1 sandwich/2 slices bread = 4 sandwiches 8 slices bread x 1 slice bologna/2 slices bread = 4 slices of bologna used 5 slices bologna - 4 slices used = 1 slice left over

Answer:
Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation
