Chemistry For You by Laurie Ryan‚ it states "As you increase the concentration of the acid‚ there are more acid particles in the same volume. Therefore there is a greater chance of acid particles colliding‚ and reacting with more particles on the surface of the marble." So‚ this means that the higher the concentration of my acid the faster the reaction. Method I will weigh out one gram of marble chips using a balance and put it in a conical flask and add to it a concentration of 50cm3

SOIL Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3000 to 12000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a time will come when there would not be enough soil left to sustain life on earth‚ because the soil is a necessary growth medium for plants‚ a home for certain insects and animals‚ as well as a medium from which we get minerals‚ such as gold.

project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is‚ the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it to

Find the Right Location 1. Observe the flow of water from rooftops‚ driveways‚ or other hard surfaces and place the rain garden where the water collects. 2. Select an area on marginally sloping or flat land. 3. Calculate the slope of your lawn (continued below). 4. Pick a spot that has full to partial sun if possible. 5. Place the rain garden at least 10’ away from a building/housing structure. 6. Call 811 or 1-800-522-6543 for OKIE811‚ the Oklahoma Company for damage prevention information before

stream of vapor-free gas is passed. A water bath is provided for maintaining a steady temperature so that there is no eddy current in the vertical tube and mass transfer takes place from the surface by molecular diffusion alone. The rate of evaporation can be followed by the rate of fall of the liquid surface. A traveling microscope is provided for determining‚ the liquid fall. With the knowledge of the concentration gradient‚ the diffusivity of the vapor of the volatile liquid can then be calculated

probes successfully landed on the surface of the Venus. However‚ the essential equipment on probes was damaged‚ leading to that it failed to get insight into the surface of the Venus. While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger
