93. Coke is an impure form of carbon that is often used in the industrial production of metals from their oxides. If a sam.
ple of coke is 95% carbon by mass, determine the mass of
coke needed to react completely with 1.0 ton of copper(II)
oxide.
2CuO(s) + C(s) → 2Cu(s) + CO2(8)

Which type of bonding involves the complete transfer of a valence electron from a less electrogrative atom to a more electronegative one

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

How many moles of cu are needed to react with 5.8 moles of agno3? cu + 2 agno3 → cu(no3)2 + 2 ag
