1. classify rust: a. c = compound b. e = element c. he = heterogeneous mixture d. s = homogeneous mixture/solution 2. classify carbon: a. e = element b. c = compound c. s = homogeneous mixture/solution d. he = heterogeneous mixture 3. classify apple juice: a. s = homogeneous mixture/solution b. he = heterogeneous mixture c. c = compound d. e = element

1. Rust, or Fe2O3, is a Chemical Compound.

2. Carbon is a Chemical Element found as C on the periodic table.

3. Apple Juice is a Heterogeneous Mixture, as it is uniform throughout. If it wasn't uniform, there would be yucky lumps in your apple juice :)

If I helped you out, I would greatly appreciate if you went through my other answers I gave you and gave them the brainliest answer :)

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
