DIAGNOSIS Othello has been diagnosed with Paranoid Personality Disorder (PPD). PPD is more common in males than females. Clients with this disorder are typically characterized by having a long pattern of distrust and suspiciousness of other people. These individuals almost always believe that other people’s motives are malicious. They assume that other people‚ including loved ones‚ will exploit‚ harm or deceive them even if there is no evidence to support the accusation. It is normal for people

Bathing‚ cooking‚ and shopping; these routine activities are seemingly second-nature for the majority of people. But for the more than seventy-nine million Americans‚ including myself‚ who have been diagnosed with either an anxiety or mood disorder‚ performing these tasks can seem like impossible feats to accomplish (“U.S. and World Population Clock”). With a combined lifetime prevalence of 24.6% (31.6% for anxiety disorders and 17.5% for mood disorders) and a combined lifetime morbid risk of 36

Hypothesis The hypothesis for this experiment stated that the sodium ion would color the flame in yellow‚ the potassium ion would color it in lilac‚ the lithium ion would color it in carmine‚ the calcium ion would color it in brick red‚ the barium ion would color it in apple green‚ and the copper ion would color it in green.

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

There is no substitute for Strontium that gives the brilliant crimson colour for fireworks and flares. Strontium does need other elements to be useful when to make red fireworks. The elements needed to make it is Strontium salts‚ Lithium salts‚ Lithium carbonate‚ Li2CO3 .To make bright red fireworks you need to include strontium carbonate SrCO3 ‚ it is also found in purple fireworks. Commonly used to make flares as well as Strontium is Phosphorus (P‚ 15) which allows things to glow in the
