A metallurgist reacts 250.0 grams of 76.0% by mass silver nitrate solution with an excess of copper
metal. How many grams of silver metal can the metallurgist produce during the process? (1 point)
Cu(s) + AgNO3 → Ag(s) + Cu(NO3)2
A. 172 grams
B. 190 grams
C. 121 grams
D. 142 grams

Which of the following elements is a representative element? a. chromium (cr) b. aluminum (al) c. mercury (hg) d. silver (ag)

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)

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
