Answer: I would think 4 because there are plants every were there like literally there is lots of flowers green bushes trees vines there's lots of wonderful beautiful stuff there so I think the number 4
Explanation:
A rainforest orchid. Orchids are very common plants in the tropical rainforest. The Amazon Rainforest itself is home to more than 40,000 plant species! The most common tree in the Amazon Rainforest is the açai here are some of the plants there are there
Bromeliads Plant (Bromeliaceae)
Emergent Plant
Heliconia Flower (Lobster-Claw)
Orchid Plant
Passion flowers (Passiflora spp.)
Lianas
Vines
Rubber Tree (Hevea brasiliensis)
Cacao (Theobroma cacao)
Giant Water Lilies (Victoria amazonica)
Answer:
Zero order
Explanation:
Looking at the data we can note a linear dependence between concentration and time.
Time Conc.
0 2
15 1.82
30 1.64
48 1.42
75 1.10
In the first 15 min it was consumed 2-1.82=0.18. So the rate is 
From 15 to 30 min (it has passed 15 min) is consumed 1.82-1.64=0.18, so as in the previous calculation the rate is 
.
From 30 to 48 (it has passed 18 min)the rate is 
From 48 to 75 (it has passed 27 min) the rate is 
So these results suggest that despite of the ever minor concentration of the reactant the rate is ever the same. Hence the reaction rate could be expressed as 
that is, the reaction is the zero order respect to C2H5I since it is not depending on concentration of C2H5I.
The balanced reaction is:
<span>4Cr(s)+3O2 (g )= Cr2O3 (s)
Since we are not given the amount of any of the reactants, we assume we have one gram of chromium. Calculations are as follows:
1 g Cr ( 1 mol Cr / 52 g Cr ) ( 1 mol Cr2O3 / 4 mol Cr ) = <span>0.005 mol Cr2O3
</span></span>0.005 mol Cr2O3 (151.99 g Cr2O3 / 1 mol Cr2O3 ) = 0.7307 g <span>Cr2O3
</span>
Therefore, the theoretical yield for 1 gram of Cr is 0.005 mol Cr2O3 or 0.7307 g Cr2O3.
Your answer for this would be A. Mixtures cannot be separated by physical meansA pure substance is heterogeneous.

Answer: The last layer
Explanation: If nothing has affected the layers we can answer this accordingly to relative dating. The older rocks should be on the bottom while the younger rocks should be on the top.
