Heat the bottom of the test tube directly in the hottest part of the flame of the alcohol burner. {/eq} of oxygen produced in the decomposition will be given by: {eq}\displaystyle{\hspace{2cm}m_o = m_{so} - m_s} Hence, the number of moles (n) of the substance in a sample will be given by the ratio of the mass (m) of the substance in the sample to the molar mass (M) of the substance and is expressed as: {eq}\displaystyle{\hspace{3cm}\mathbf{n = \dfrac mM}} Upon decomposition of 5.34 g of silver oxide, 4.97 g of metallic silver is obtained. The specimen was placed into a furnace and the carrying gas transfered the products of decomposition into an oxygen analyzer. © copyright 2003-2020 Study.com. After a couple of minutes, the silver oxide will begin to turn silver and the balloon will inflate slightly. In a decomposition reaction, silver oxide breaks down into two chemical elements, metallic silver and oxygen gas. Calcium consists of five stable isotopes. The number of moles of solute in a bottle... How many moles are in 1.30 g of (NH4)2SO4? Services, What is Molar Mass? The mass {eq}(m_o) n_o &\approx \boxed{{\mathbf{0.0116 \ mol}}}\\ We know that the molar mass of a substance is the mass of one mole of the substance. - Definition, Method & Practice Problems, What is Atomic Mass? We hypothesized that the decomposition of Ag2O could be used in the bonding of Ag to various Si-materials by taking advantage of the good adhesion between the intermediate forms of Ag and the silicon oxide. {/eq}.

Aluminum reacts with sulfuric acid to produce... What is the mass in grams of copper chloride... A gas has a density of 1.25 g/L at STP. n_o &= \dfrac{m_{so} - m_s}{M_o}\\[0.3cm] \hspace{2cm}n_o &= \dfrac{5.34 \ \rm g - 4.97 \ \rm g}{32 \ \rm \dfrac{g}{mol}}\\[0.3cm] {/eq}, The molar mass of oxygen: {eq}M_o = 32 \ \rm \dfrac{g}{mol} In a decomposition reaction, silver oxide breaks down into two chemical elements, metallic silver and oxygen gas. Continue heating until all of the silver oxide has decomposed. {/eq}, The mass of the metallic silver: {eq}m_s = 4.97 \ \rm g A silicon oxide (i.e. The observation of Ag 2 O thermal decomposition was realized by means of an arrangement using a galvanic concentration cell with a solid electrolyte. Stretch the balloon over the mouth of the test tube. {/eq}. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. {/eq}. Therefore, the number {eq}(n_o) SiOx) layer is generally formed on the surface of Si-materials as a native oxide film. {/eq}. Our experts can answer your tough homework and study questions. Silver oxide particles/silver nanoparticles interconversion: susceptibility of forward/backward reactions to the chemical environment at room temperature. n_o &= \dfrac{m_o}{M_o}\\[0.3cm] Upon decomposition of 5.34 g of silver oxide, 4.97 g of metallic silver is obtained.
