Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

Fact: Everyone has heard at least one Salt-N-Pepa song. Now‚ hear me out‚ I know you recognize these lyrics: “Let’s talk about sex‚ baby/let’s talk about you and me/let’s talk about all the good things/and the bad things that may be.” That song is appropriately titled “Let’s Talk About Sex‚” and it is a ballad about safe sex and sexual awareness as a whole. Salt‚ Pepa‚ and DJ Spinderella cried out against the lack of conversation about sex in the ‘90s because they believed in normalizing sex‚ especially

With the abandonment of a hunting-gathering way of life and the rise of permanent settlements and eventually cities‚ the human population has undergone dramatic growth. "It took until after 1800‚ virtually all of human history‚ for our population to reach 1 billion. Yet we reached 2 billion by 1930‚ and 3 billion in just 30 more years‚ in 1960" (Withgott & Brennan‚ 218). Today the world ’s population has grown to an estimated 6.5 billion people. "Increased population intensifies impact on the environment

Economic Growth Economic growth is the increase in the amount of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product‚ or real GDP. Growth is usually calculated in real terms‚ i.e. inflation-adjusted terms‚ in order to obviate the distorting effect of inflation on the price of the goods produced. Economic growth typically refers to growth of potential output‚ i.e.‚ production at "full employment". It

and identification of Bacterial isolates An enrichment culture technique was used for the isolation of bacteria responsible for biodegradation of phorate in soil. Screening of these bacterial species for phorate degradation in liquid cultures in our previous study (Jariyal et al.‚ 2014)‚ resulted in identification of bacterial species B. aerophilus strain Imbl 4.1 ‚ Brevibacterium frigoritolerans strain Imbl 2.1 and Pseudomonas fulva strain Imbl 5.1.

ECONOMIC GROWTH is the long term expansion of a country’s productive potential Short term growth is measured by the annual % change in real national output – this is mainly driven by the level of aggregate demand (C+I+G+X-M) but is also affected by shifts in SRAS Long term growth is shown by the increase in trend or potential GDP and this is illustrated by an outward shift in a country’s long run aggregate supply curve (LRAS) Key drivers of growth There have been numerous research studies in

population poli~y whose main fo~us was the reduction of the rapid population growth. The main population program was the family planning program aimed at providing contraceptive technology to reduce fertility. The rapid declines in fertility noted in some countries have been attributed in varying extent to the impact of such programs. It was difficult‚ however‚ to assessthe impact such program has had on the population growth since the countries that had achieved the most rapid declines in fertility

This chapter identifies inequality patterns across OECD countries and provides new analysis of their policy and non-policy drivers. One key finding is that education and anti-discrimination policies‚ well-designed labour market institutions and large and/or progressive tax and transfer systems can all reduce income inequality.
