Can you me with #7? #7 says "a substance enters into and is altered through the course of a chemical change. it is called a " pick one of these choices. the lines that are next to the words are already picked from #s 1, 2, 3, 4, 5,& 6. do not pick more than one answer pick one answer only. tap the image so you could see the full image. (what i'm talking about is science.)

Be sure to answer all parts. the following equilibrium constants were determined at 1123 k: c(s) + co2(g) ⇌ 2co(g) k'p = 1.30 × 1014 co(g) + cl2(g) ⇌ cocl2(g) k''p = 6.00 × 10−3 calculate the equilibrium constant at 1123 k for the reaction: c(s) + co2(g) + 2cl2(g) ⇌ 2cocl2(g) 4.68 × 10 9 (enter your answer in scientific notation.) write the equilibrium constant expression, kp:
