pH What is pH?  PH is a measure of how acidic or basic the solutions is What are pH values? The pH count with a scale of 0-14. Many acidic solutions have lower pH values, and a solition with pH 0 is highly acidic and with pH -7 is neutral, pH -14 is extremely basic. Do this values depend on something? Explain your answer. It depends on the scale rage in  the pH scale is from 0-14 where pH-0 is highly acidic and 14 is extremely basic. What is Neutralization?Give Example Is the interaction that occurs between acids and bases in wich the properties of each are canceled out by the other.   Example: Perhapsmylou've heard someone complain about heartburn or an upset stomach after easting a large meal. To feel better, the person may have taken an atiacid. How do antiacids? Heart or stomach discomfort is caused by excess break hydrochloric acid in the stomach. Hydroloric acid helps break down the food you eat,but too much acid can irritate made from the ase
VARIABLE AND CONTROLS -Scientists design experiments in much the same way. They take great care to make sure only one factor in the experiment, the indepent variable, is changed. The independent variable in your experiment is the brand of sports drink. The factor that changes as a result of the independent varible is called dependent variable.  The dependent variable in your experiment is the mass of dry material. Controls are factors that are kept the same, providing a basis for comparision. Controls in your experiment are the identical jars, amount of drink, and the temparature of the plate.

COMPARING AND COSTRASTING Compare and contrast the following types of solotions: the active material in  a helium-neon laser(glow like a neon light), bronze (coopper-tin), cloudy ice cubes, and ginger ale.  SIMILATIRIES That the matirials have solute, can be another liquid, a gas or even a solid also the solution combined like liquids-solution, gas-liquid, gas-solid. All of the solution can change to another,also can be divided or separated. Differences That liquid is made of 1 type of molecules where a solution is made of 2 types of molecules, is a homogenoes mixture of substances in a liquid form. Also is there forms and their particles. PD: sorry Mr i was a little bit late
SCIENCE WORK
How a modern scientist and one from the 1800s communicated their data  with other scientists? 1800 In 1800 scientist use books and they comunicated by cards and by talking each other 2017 Now scientist use internet to make they life easier, they comunicate by calls with phones and new techologic advaces make more experiments.
WHAT IS ENERGY Energy  is the ability to do some work, all things need energy to move. Energy can be stored. ELECTRICAL ENERGY like when the light bulbre give light HEAT ENERG Y  like when fire gives heat. MUSCULAR ENERGY is when you move your body. SOLAR ENERGY is the energy that come from the sun. HYDEL ENERGY is when the water moves something with them own force. WIND ENERGY  the big fans gives elctrical energy.
