These findings show that the null hypothesis is rejected, and that there is a major difference between the observed and expected values. It is also observed that in the data in Figure 1.1, as the concentration of the NaHCO3 increases, the greater the production of oxygen. The highest photosynthetic rate is in at a 1.0% concentration of NaHCO3and the lowest in at a 0.1% concentration of NaHCO3. It is also important to note that the 0.4% concentration of NaHCO3 had a greater oxygen production than the 0.6% concentration of NaHCO3.
Cassie Droelle 1510-01501 Chemical Equation 2 Visualizing Stoichiometry – Inquiry Lab Cassie Droelle 1510-01501 4-18-16 Introduction The purpose of this lab is to determine the complete balanced equation of a metathesis reaction with an unknown metal ion by first experimentally identifying the metal ion and then using stoichiometry to determine the rest of the equation. Stoichiometry is “the process by which quantities in a chemical reaction are compared” and is based on the Law of Conservation of Mass (1). The Law of Conservation of Matter “dictates that the mass of the reactants and mass of the products must be equal” (1).
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
The law of conservation of mass states that mass can neither be destroyed, nor created during a chemical reaction, and that the mass of the products should equal the mass
During this week, we performed the Meiosis pipe cleaner project and completed worksheets pertaining to meiosis. Afterwards, we took notes on karyotyping and finished worksheets for it. Regarding the meiosis pipe cleaner project, it is similar to the mitosis project since the chromosomes have a specific color key to them. However, in the meiosis project, we incorporated alleles in the chromosomes, by representing them with tightly loop pipe cleaners around the legs.
●5H2O? b. What is a possible chemical equation for the decomposition reaction? 10.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
Purpose The purpose of this experiment is to determine K, the rate constant k1 of the forward reaction divided by the rate constant k-1, as well as Ymax, which is the maximum number of moles of acetic acid that can be adsorbed on the surface of the charcoal, per gram of charcoal. Methods
1. What is the law of the conservation of energy? Who is credited for its formulation? The law of the conservation of energy has many parts. It states “…energy is neither created nor destroyed.
My claim is photosynthesise models the Law of Conservation of matter and energy that no atoms would be able to be created or destroyed only rearranged. My evidence to support my claim is the Law of Conservation of matter states No atoms can be created or destroyed. This chemical equation “6CO2+6H2O-->C6H12O6” (Discovering the secrets of Photosynthesis, 2017. This represents only atoms can only be rearranged.
Quinn Nguyen Floating Leaf Disk Photosynthesis Lab Conclusion: Graph your results for all 3 trials on one graph. Label the graph, both axes, and provide a legend to distinguish each trial. What was the rate of photosynthesis for each variable? How many leaves floated per minute? Rate of photosynthesis (leaves/min) Spinach: (2-0)/25 = 0.08
Plants pull a quarter of the world’s carbon dioxide from the sky every year. This does not mean that in four years the atmosphere will be completely absorbed of its carbon dioxide. The reason for this is simply the carbon cycle. The Carbon cycle is a very complex process that can be explained in two different ways. The first process is the slow carbon cycle, and the second is the fast carbon cycle.
In this report I am going to describe the process that occurs when plants and human beings create oxygen and carbon dioxide. Plants make oxygen through photosynthesis. To do this plants need certain things. Firstly they take in water through their roots from the earth below.
As oxygen was a visible product, we counted the oxygen bubbles made when we moved the source of light. Hypothesis: Plants need light to photosynthesize. In this experiment, the light intensity is changed by changing the distance of the source of light closer or further away from the elodea, so theoretically, when the intensity becomes stronger due to the light source being closer to the Elodea, the rate of photosynthesis should increase and
This is very similar and related to the previously discussed objective of being able to identify biological processes that require energy. Modeling the way organisms capture and store free energy was achieved in several different labs, including the cellular respiration lab. In the lab, we modeled how an organism can capture and use energy through facilitating the germination of seeds. Germination is a very complex biological process that requires the capture and storage of energy for later use. Modeling this process allows further investigation and greater understanding of how energy is captured and used by
