What is PH? 2.What are PH values? Do these values depend on something?  Explain your answers. 3.   Check Chart 3.2 about acids and bases. What can you explain about it? 4. What is Neutralization?    Give examples. 1  1 IS A MEASUASURE OF HOW ACIDIC OR BASIC THE SOLUTION IS  ,  2 IS A NUMBER FROM 1 TO 14 WITH 7 AS THE MIDDLE(NEUTRAL) POINT     VALUE BELOW  7 INDICATE ACIDITY WHICH INCREASE AS THE NUMBER DECREASE,1 BEING THE MOST ACID         VALUE ABOVE  7 INDICATE ALKALINITY WHICH INCREASES AS THE NUMBER INCREASES                       ,14BEING THE MOST ALKALINE                  3 THE STRENGTH OF SOME ACIDS AND BASES DISSOCIATED TO FORM IONS            A STRONG ACID OR BASE DISSOCIATES 100 WHILE A WEAK OR MODERATELY WEAK ONE DISSOCIATES LESS THAN 100                4 NEUTRALIZATION IS THE INTERACTION THAT OCCURS BETWEEN ACIDS AND BASES IN WHICH THE PROPERTIES OF EACH ARE CANCELED OUT BY THE OTHER           EXAMPLES      

SKILL BUILDER PAGE 80 SEPARATING AND CONTROLLING VARIABLES scientists pay close attention to controls,dependent variables when they design experiments. do the chapter 3 skill activity on page 844 to learn how to identify controls and variables INDEPENDENT⇒⇒⇒ THE ONE THING YOU CHANGE. LIMIT TO ONLY ONE IN AN EXPERIMENT                          EXAMPLE THE LIQUID USED TO WATER THE PLANT DEPENDENT⇒⇒⇒ THE CHANGE THAT HAPPENS BECAUSE OF THE INDEPENDENT VARIABLE                    EXAMPLE THE HEIGHT OF HEALTH OF THE PLANT CONTROLLED⇒⇒⇒  EVERYTHING YOU WANT TO REMAIN CONSTANT AND UNCHANGING                      EXAMPLE TYPE OF THE PLANT USED,POT SIZE,AMAUNT OF LIQUID,SOIL TYPE ,ETC 

comparing and contrasting when we compare the helium neon later,bronze,cloudy ice cubes, and ginger ale, we can get different types of solutions making all the mixtures in between them. we can get  gas-liquid gas-solid liquid-solid

how modern scientist communicate their data to other scientists my opinion is what are three methods  is limited if that knowledge is not communicated to other people. Scientists often communicate their research results in three general ways. One is to publish their results in peer-reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to presentations. Scientists also present their results to certain departments at universities. Third, scientists publish about their work in popular media, such as magazines, newspapers, and blogs. how 1800s scientist communicate their data to other scientist  most common way for scientists to communicate their research results is to present the results at conferences. Conferences can range from several dozen attendees to tens of thousands of attendees. Conferences are places where scientists not only share their latest research fin

types of the energy that the video  the energy is everything that we do and are different types of energy  KINECTIC ENERGY The energy associated with an object’s motion is called  kinetic energy . A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.  POTENTIAL ENERGY Let’s return to our wrecking ball example. The motionless wrecking ball doesn’t have any kinetic energy. But what would happen if it were lifted two stories up with a crane and suspended above a car? In this case, the wrecking ball isn't moving, but there is, in fact, still energy associated with it.  CHEMICAL ENERGY s energy stored in the  .  It is released in a chemical reaction, often producing heat as a by-product  Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Usually, once chemical energy is released from a substance, that substance is transformed into an entirely new substance. ELECTRICAL ENE
