as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete. When the water freezes in the concrete‚ the pressure of frozen water increases

Thermochemistry Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both‚ the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one. System to surroundings: Surroundings to system:

____________ Properties of Water Lab Introduction: Water is a simple molecule‚ yet itʼs most vital to all living things. It has the highest specific heat of everyday substances. Unique properties of water enable it to carry out functions that no other substances can. In a neutral aqueous solution‚ five molecules of water are bonded together by weak hydrogen bonds. Furthermore‚ due to the electronegativity of oxygen‚ water is a polar molecule. Due to its polarity‚ water is classified as the universal

Uses of water: 1. For drinking and for life processes. On an average‚ a man consumes about 60‚000 to 80‚000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up. Aqueous solutions fill the cells in the body. Nutrients‚ oxygen‚ and metabolic waste products are transported by blood‚ which is mostly water. Digested food is absorbed in the form of an aqueous solution. In plants too

“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual
