WATER
Percentage of water found in...
Blood: More than 80% water
Muscles: 79%
Bones: 31%
Fat cells: 10-15%
CELL LIFE
Water is a carrier, distributing essential nutrients to cells, such as minerals, vitamins and glucose.
CHEMICAL AND METABOLIC REACTIONS
Water removes waste products including toxins that the organs’ cells reject, and removes them through urines and feces.
TRANSPORT OF NUTRIENTS
Water participates in the biochemical break-down of what we eat.
BODY TEMPRATURE REGUALTION
Water has a large heat capacity, which helps limit changes in body temperature in a warm, or a cold environment. Water allows the body to release heat when ambient temperature is higher than body temperature (1). The body begins to sweat, and the evaporation of water from the skin surface very efficiently cools the body.
ELIMINATION OF WATER
Water is an effective lubricant around joints. It also acts as a shock absorber for eyes, brain, and spinal cord and even for the fetus through amniotic fluid.
Water is at the center of life. This is why nobody can live more than 3 to 5 days without any water intake.
HOW TO TELL IF YOU’RE HYDRATED?
The best way to tell if you're hydrated is to monitor your urine. You should be urinating a significant amount regularly (3-4 times) throughout the day. If your urine is pale yellow or clear in color you are drinking enough. If it is dark yellow and odorous, get a big glass of water and start guzzling! Keep in mind that a vitamin pill will also make your urine dark - so it is possible to have dark urine and still be hydrated.
WHAT ARE ELECTROLYTES?
Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body's blood chemistry, muscle action and other processes. Sodium, calcium, potassium, chlorine, phosphate
does not produce pollution or contribute to global warming because the only product is water. Advantages of a Hydrogen Fuel Cell 1. It can be a renewable source of electricity if the hydrogen comes from a renewable resource. See the advantages of hydrogen as a fuel. 2. It does not produce pollution or contribute to global warming because the only product is water. A hydrogen fuel cell is made from an anode and a cathode with an electrolyte contained between them. The fuel cell generates electricity. It…
gas (g). If water is the solvent, then solutions are called aqueous solutions! • A saturated solution means that the maximum amount of solute has been added to the solvent and no more will go into solution. Electrolytic Properties • All aqueous solutions can be classified in terms of whether or not they conduct electricity. Forms ions in solution _________ electrolyte conducts electricity Table salt or NaCl Doesn’t Form ions in solution nonelectrolyte ___________ Methanol in water Doesn’t…
27 Fluid, Electrolyte, and AcidBase Balance Part I Chapter 25 Objectives: Fluid, Electrolyte, and Acid–Base Balance Body Water Content Infants have low body fat, low bone mass, and are 73% or more water Total water content declines throughout life Males about 60% water; females are around 50% This difference reflects females’: Higher body fat Smaller amount of skeletal muscle In old age, only about 45% of body weight is water Body Fluid Compartments In lean adults, body fluids…
weak, and/or soft, have low melting and boiling points, are poor conductors of heat and electricity, and tend to be insoluble in water. On the other hand, ionic compounds are bonded metals and nonmetals and are thus crystalline, hard or brittle solids, have high melting and boiling points, are good conductors of heat and electricity, and most are soluble in water. When both of these types of compounds are placed in an aqueous solution, an ionic compound will disassociate completely, meaning…
when dissolved in water Acid-base neutralization reaction: a process in which an acid reacts with a base to yield water plus an ionic compound called a salt Activity series: a lost of elements in order of their reducing ability in aqueous solution Base: a substance that provides OH- ions when dissolved in water Diprotic acid: an acid that has two dissociable protons Dissociate: splitting apart to give ions when dissolved in water Electrolyte: a substance that dissolves in water to produce ions…

It provides energy to operate lights and accessories and to start eh engine. -It also serves as a voltage stabilizer Lead-Acid Battery:…
foil, electrode) is immersed in electrolyte near the porous electrode which has air on one side and electrolyte on the other side (aluminium’s side). The choice of electrolyte is various. It can be common salt (NaCl) or alkaline solution (KOH), sea water can also be used but only specific type of the alloys of aluminium can be used. The porous electrode can be made of granules of activated charcoal (mostly made of carbon) which prevents the leakage of electrolyte. Anode: The silvery aluminium…
conduct of electricity, therefore we can measure their conductivity by dissolves them in distilled water (ionic compounds will produce ions and enable the solution to conduct the electricity) and then classify them into three kinds of electrolyte: nonelectrolytes (not dissociate, have very low conductivity), strong electrolytes (totally dissociate, have very high conductivity), and weak electrolytes (dissolve a little, have not very low but not very high conductivity). In this way, in the first…

Chapter 2 Chemical Basis of Life 1. Distinguish between chemistry and biochemistry. Chemistry is the study of the composition of substances and how they change. Biochemistry is the chemistry of living organisms. 2. Define matter. Matter is anything that has weight and takes up space. 3. Explain the relationship between elements and atoms. An element is a basic substance that other things are composed from. Each individual element is made up of tiny, invisible particles called atoms. The atom…
