2:32 PM Wed Oct 2 < Question 4 of 10 6% Submit If 61.0 g of AgNO3 (FW 169.87 g/mol) is added to a solution containing 45.0 g of CaBr₂ (FW 199.89 g/mol), what mass, in g, of AgBr (FW 187.77 g/mol) precipitate will be formed? The balanced equation is 2 AgNO3(aq) + CaBr2(aq) → 2 AgBr(s) + Ca(NO3)2(aq)

Modern commercial airliners are largely made of aluminum, a light and strong metal. But the fact that aluminum is cheap enough that airplanes can be made out of it is a bit of historical luck. Before the discovery of the Hall-Héroult process in 1886, aluminum was as rare and expensive as gold. What would happen if airplanes had to be made of steel? The fuselage of the Boeing 777, which can carry 305 passengers, is approximately a hollow aluminum cylinder without ends, 64.0 m long, 6.2 m wide, and 2.5 mm thick (see sketch at right). The fuselage of an airplane Suppose this fuselage was made of steel (density 7.87 g/cm³) instead of aluminum (density 2.70 g/cm³), and let's say the average passenger has a mass of 81 kg. We'll also assume the engines can't lift any greater mass than they already do. Calculate the number of passengers that the Boeing 777 could carry if its fuselage was made of steel. X Ś

Which alloy is a combination of metal and non-metal? Steel O Bronze O Solder O Brass

For each reactions that follow, decide whether the reaction is a redox reaction, acid-base reaction, electrophile-nucleophile, or something else. One can begin to identify the type of reaction by looking to see if oxidation numbers of atoms that take part in the reaction change during the reaction. You will need to draw out the structures. i. If the reaction is considered an acid-base reaction, draw out the full mechanism for the reaction. Be sure to indicate which compound is the acid, base, and conjugate acid and base (where possible). If the reaction is considered a redox reaction, be sure to indicate which ii. species are oxidized and which are reduced. For every reaction you will need to justify your identification of the type of jii. reaction (redox/acid-base/electrophile-nucleophile).

hey! i’m having a bit of trouble with my chemistry homework did I do this correctly if not can you explain to me what I got wrong and tell me the answer as well!?

1◄ Cancel RESET 3. Aluminum metal is produced by heating aluminum oxide, Al₂O3(s), and other substances to almost 1000 °C until the mixture melts. Molten aluminum oxide is an excellent conductor. An electric current passed through liquid aluminum oxide can provide the electrons needed to convert the aluminum ions to neutral metal atoms. Explain the following properties of aluminum oxide in terms of ionic bonding: IK/U (a) its high electrical conductivity when molten (b) its high melting point A fy Ⓒ Done

Match each statement in the left column of the table below with a compound on the right. In your answer, write the name of the matching compound against the number of the statement, eg. a) Hg Note that each compound must be matched with only one statement. If a compound can be matched with more than one statement (or vice versa), it is up to you to find the BEST match. a) A metal that is in the liquid phase at room Sio2 temperature. CO2 b) A compound that forms a network solid KNO3 composed of covalently bonded atoms. c) A gas that will dissolve in water due to Poly-ethylene (a plastic) dipole – induced dipole forces. Graphite d) The solid-liquid equilibrium line on the H20 phase diagram of this compound has a negative slope. NH3 e) A solid substance at STP, in which the Hg particles are held together by induced 12 dipole - induced dipole forces. f) A substance that will dissolve in water due to hydrogen bonding. 8) A covalent network solid that has good electrical conductivity. h) An…
