The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn‚ wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed‚ the sugarcane

Wiener (2017) discusses how the Denti-Cal is a broken system; especially within the older population. Denti-Cal is a program through Medi-Cal that helps low-income individuals. Unfortunately‚ this program was not active in California between 2009-2014 (Wiener‚ 2017). However‚ the program was brought back in 2015‚ but the new program is not cutting it. Denti-Cal has many holes that include low reimbursement rates‚ restrictive rules‚ and only a handful of Denti-Cal providers (Wiener‚ 2017). Additionally

Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions
