Ph

September 27/ 2017.

1. What is Ph?
Is a measure of how acidic or basic the solution is.

2. What are Ph values? Do these values depend on something? Explain your answer.

Is a scale ranges 0 to 14 with 7 as the middle neutral point.
* of  0 - 6 is an acidic  Ph , 0 being the most acid.
* 7 is neutro.
* of 8 - 14 is an alkaline Ph , 14 being the most alkaline.

3. Check chart 3.2 about acids and bases.  What can you explain about it?

*Strong acid are: hydrochloric, sulfuric, nitric.
*Strong bases are: sodium hydroxide and potassium.
*Week acid are: acetic, carbonic and ascorbic.
*Week bases are: ammonia, aluminum hidroxide, iron hidroxide.

4. What is neutralization? Give examples.

Is the interaction that occurs between acids and bases in which the properties of each are canceled out by the other.

Example: acidity stomach: the people have some antiacids to neutralize the acid stomach.

Separating and  Controlling Variables. September 26/17 * when carrying out and experiment the scientists have very in mind: controls, dependent variables and independent variables. *  What is a variable? in an experiment a variable indicates an amount or a condition that can change. * Dependent variable: it is a variable that we observe and measure. * Independent variable: it is a variable that we can control. * Control: provides a basis of comparison in the experiment. 1.procedure page 844  point 1-6 *The salt is independent variable. *Temperature of water is the dependent variable. *The volumen of water is control. 2.Ten grams of sugar dissolves more quickly in a liter of pure, hot, tap water than in a liter of  pure, cold, tap water.  List the controls, the indepent variable an the dependent variable. *the velocity of dissolves sugar in the water is the dependent variable. *the temperature and sugar is the independent variable. *the control is the volumen o

COMPARING AND CONTRASTING. We find different states of matter:  Solid  Liquid  Gaseous  And these can be transformed back in the  others states.  Example:  Liquid - Solid  Solid - Liquid  Liquid - Gaseous  Gaseous - Liquid  If we compare Helium- Neon laser, bronze,  cloudy ice cube, and ginger ale, we can  observe different types of solutions with  different states of matter. Of these  elements we can obtain:  Helium/ gaseous - neon laser/ liquid  Bronze/ solid - Cloudy  ice cube/ solid  Ginger ale/ liquid.

the nuclear atom

Imagen
  THE NUCLEAR ATOM ATOMIC MODEL  is a representation of a atom ALPHA PARTICLE Consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. ELECTRON Is a negatively charged. NUCLEUS Is the small dense región consisting of proton and neutrón at the center of an atom. PROTON A positively charged, elementary particle that is a fundamental constituent of all atomic nucleus. NEUTRON An elemetary particle having no charge, mass slightly greater than that of a proton and spin of ½ : a constituent of the nucleus of all atoms except those of hydrogen. Symbol N.
