Use the periodic table to determine how many grams of oxygen would be required to react completely with 859.0 g C2H2?
Alekssandra [29.7K]
 <span>(a) The balanced equation shows that 2 moles of water result from 5 moles of 
oxygen that reacts, so that is 0.4 times as many moles of water as O2. So if we 
have 2.50 moles of oxygen reacting, we produce 0.4 times that amount, or 
1.0 mole of water. 
(b) The molecular weight of acetylene is 26 and that of O2 is 32, so we can set 
up the proportion: 2.25 gm. / 52 = x gm. / 160 
Then x grams = (2.25)(160) / 52 = 6.923 grams of O2 are required. 
(c) The balanced equation shows that twice as many moles of CO2 are produced 
as we have acetylene reacting. If 78.0 grams of acetylene react, that is 3 moles 
so we produce twice that, or 6 moles of CO2. The molecular weight of CO2 is 44, 
so we have 44 times 6, or 264 grams of carbon dioxide produced. 
(d) If we collect 186 grams of CO2, the percentage yield is: 
186/264 = 0.7045, or 70.45 percent yield.

REY [17]

Aerospace

Thermoset composites are being specified for wings, fuselages, bulkheads, and other applications in commercial, civilian and military aerospace applications.

Appliance/Business

Thermoset composite are being used in frames, equipment panels, handles and trims in appliances, power tools, business equipment and many other applications.

Thermoset composites for the appliance industry are used in washers, dryers, refrigerators, freezers, ranges, ovens, dishwashers for components that include control panels, handles, knobs, vent trims, side trims, motor housings, kick plates and many others.

Automotive/Transportation/Farm/Construction

Composites are now being used in vehicle and equipment applications, including, panels, frames, interior components and other parts.

Civil Infrastructure

Some composite infrastructure applications include buildings, roads, bridges and pilings.

Construction

Thermoset composites are replacing many traditional materials for home and offices architectural components including fixtures, doors, wall panels, roofing, window frames, moulding, vanity sinks, shower stalls and even swimming pools.

Corrosive Environments

Composites are ideal for applications in corrosive environments, such as chemical processing plants, pulp and paper converting, oil and gas refineries and water treatment facilities.  Common applications include fans, grating, tanks, ducts, hoods, pumps and cabinets.

Electrical

With strong dielectric properties including arc and track resistance, Thermoset components include substation equipment, microwave antennas, standoffs and pole line hardware and printed wiring boards. Applications and components include switchgear,  motor controls,  standoff insulators, control system components,  circuit breakers,  arc chutes, arc shields, terminal blocks,  terminal boards,  metering devices,  bus supports and lighting components.

Marine

With their corrosion resistance and light-weighting attributes, Marine composite applications include boat hulls, bulkheads and other components for military, commercial and recreational boats and ships.
