Plz hurry it's urgent! which is the correct balanced equation that shows the process of iron oxide (fe2o3) explosively combining with aluminum (al) to produce iron (fe) and aluminum oxide (al2o3)? a. fe2o3 + al → fe + al2o3 b. fe2o3 + 3al → 3fe + al2o3 c. fe2o3 + 2al → 2fe + al2o3 d. 2fe2o3 + 2al → 2fe + 2al2o3

easy

explanation:

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
