Lab Write Up Pre-Lab Questions: 1. What precipitation reaction could be used to separate and remove silver ions from a mixture containing iron (III) and zinc ions? A precipitation reaction that could be used is hydrochloric acid Ag+(aq) + HCl(aq) AgCl(s) +H+(aq) – white. 2. What precipitation reaction could be used to separate and remove iron (III) ions from the remaining mixture containing iron (III) and zinc ions? Fe3+(aq) + 3NaOH(aq) Fe(OH)3(s) + 3Na+(aq) 3. How can the presence of silver

Animals hunker down‚ able to find only enough food to keep warm. The tundra is an unusually cold and dry climate. Precipitation totals 6-10 inches of rain a year‚ which includes melted snow. This is almost as little as the world’s driest deserts. Coupled with strong and drying winds‚ the tundra is an extreme weather biome. The tundra seems like a wet and soggy place because the precipitation that falls evaporates slowly‚ and because of the poor drainage caused by the permafrost. You can find the tundra

A desert is a landscape or region of land that is very dry because of low rainfall amounts (precipitation)‚ often has little coverage by plants‚ and in which streams dry up unless they are supplied by water from outside areas.[1] Deserts can also be described as areas where more water is lost by evapotranspiration than falls as precipitation.[2] Desert plants must have special adaptations to survive with this little water. Deserts take up about one third (33%) of the Earth’s land surface.[3] Bottomlands

Eventually they will get so big that the swirling atmosphere can no longer hold them up. The droplets then fall from the sky as PRECIPITATION. Precipitation can be in the form of rain‚ snow‚ sleet or hail depending on other conditions. Once the precipitation reaches the ground‚ several things can happen to it. First‚ it might be re-evaporated. Some of the precipitation will be absorbed into the ground. Once in the ground‚ the water can join the earth’s ground water supply. This is one of the

Title: Stoichiometry of a Precipitation Reaction Purpose: The purpose is to predict the amount of precipitation using stoichiometry. Another purpose is to measure and calculate percentage yield. Procedure: 1. Weigh out 1.0g of CaCl2*2H2O and put it into a 100mL beaker. 2. Add 25mL of distilled water and stir. 3. Using stoichiometry to determine how much Na2CO3 is needed for a full reaction. 4. Weigh the calculated amount and put it in a small paper cup. Add 25mL distilled water and stir

Relative humidity has also a physiological significance‚ as it determines the efficiency of the water-evaporating phase of our body cooling mechanism. It is also an important source of all forms of condensation and precipitation‚ where there is little moisture in the air; the precipitation will be low as compared to high atmospheric moisture. As the air is a principal absorber of solar energy and earth radiant energy as well‚ water vapor operates as a heat regulator and so have great effects on air

Winter and Summer in Canada All places on earth have weather. Weather can be wonderful or it can be terrible. Sometimes it benefits human activities whereas other times it is destructive. Weather has different components which involve precipitation and climate. Both these parts affect human life on earth. They determine what we can do and when we can do it. Canada is a little different from most countries. Canada has two dramatically different seasons in regard to temperature‚ weather and activities

Geography In New Jersey there are a lot of landforms. New Jersey land rank is 46.They have 7‚417 square miles of land. The four major land regions are; The Appalachian Ridge‚ New England Upland‚ The Piedmont‚ and last but not least‚ The Atlantic Coastal Plains. The Appalachian Ridge contains the lesser mountains of the Great Appalachian mountain chain. The New England Uplands are called highlands and it holds many beautiful lakes. Piedmont is where the largest cities are located. The Atlantic

of sulfate in a sample is done as an instrument of learning a quantitative method of analysis‚ i.e.‚ of the gravimetric analysis. This type of analysis‚ which makes use of the weight of the samples was used for the experiment and required the precipitation of our analyte‚ SO4-2‚ and its filtration as a BaSO4 precipitate so as for weighing it. The weight of the SO4-2 was determined through the data gathered in the experiment‚ particularly from finding the weight of the BaSO4 precipitate. This was
