Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

Inhaled Flolan Vs Inhaled Nitric Oxide Which one is a better option? Abstract: Nowadays vasodilators are administered directly via the airway to treat pulmonary hypertension and to recover pulmonary gaseous exchange. Many scientific studies focus on this new therapeutic concept which was initiated by using exogenous nitric oxide (NO) gas. It selectively dilates pulmonary vessels without associated systemic vasodilation. But in recent years alternatives of NO were proposed due to NO’s potential

understanding of the mole. METALS Reacting Gas Volumes AIM: to investigate the relationship between the volumes of gases involved in a reaction. HYPOTHESIS: A new gas will form when two gases will react together. BACKGROUND INFORMATION: Nitric oxide and oxygen are both colourless gases which do not dissolve in water. However‚ when they mix they form a different gas called nitrogen dioxide which is brown‚ soluble in water and has a particular odour. This is an example of two gases reacting

used by millions of athletes today‚ and there have been a lot of questions raised about the long-term effects of them. There are a lot of different brands in this industry‚ but most of the products contain the same main ingredients: Creatine‚ nitric oxide‚ vitamin B‚ and caffeine. There has been quite a bit of research done on these ingredients individually‚ but together they have not been studied very much‚ which is why a lot of athletes avoid them. Another problem with these products is that

First‚ prepare a data table. Record what you see throughout the laboratory activity. Your teacher will demonstrate for the class the reaction of metallic copper with concentrated nitric acid‚ HNO3. This must be done in the fume hood. (Caution: Avoid breathing poisonous gases. Avoid contact of skin with nitric acid. It burns skin and clothing.) One student will be asked to feel the side of the demonstration beaker and report to the group. The products formed are copper(II) nitrate solution‚ Cu(NO3)2(aq)

Preparation Nitrosyl chloride can be prepared by the reaction of nitric oxide with chlorine: 2NO + Cl2 → 2ClNO Also‚ nitrosyl chloride is produced by the action of chlorine on sodium nitrate; or by the reaction of nitrosyl sulfuric acid with hydrochloric acid: NaNO3 + Cl2 → ClNO + NaClO2 ONHSO4 + HCl → ClNO + H2 SO4 Nitrosyl chloride also is obtained as a byproduct in the manufacture of potassium nitrate from potassium chloride and nitric acid: 3KCl + 4HNO3 → 3KNO3 + Cl2 + ClNO + 2H2O In the above
