100 points pls help :') Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help

you write a clear and concise report that summarizes the lab you have just completed. The lab report is composed of four sections: Section I: Experimental Overview o Provide background information. o Include the hypothesis(es). o Summarize the procedures. Section II: Data and Observations o Summarize the data you collected in the lab guide. o Include information from data tables. o Include any written observations that are relevant. Section III: Analysis and Discussion o Discuss any important calculations or formulas used. o Identify key results, what the results indicate, and any trends in the data. o Include graphs (if constructed) that display trends in the data. o Provide possible reasons for any problems with the experiment, or unexpected data. Section IV: Conclusions o Identify if the hypothesis(es) was (were) supported or refuted. o Provide logical reasoning based on data. o Explain how the experiment could be improved.

              The purpose of this guide is to help you write a clear and concise report that summarizes the lab I just completed.  This lab showed me how water carries rocks to a new location. For instance how the first model showed how a stream would act with light drizzle to downpour as I saw the outcomes were all if not completely then partially different  

             I read the information that was given to me before I started each lab lesson and went on from there.

             Just say something that you think you could have done better in two to three sentences

tresset_1 [31]
<h3>Answer:</h3>

B. a compound

<h3>Explanation:</h3>
  • A mixture is a substance that is made of two or more components that are not chemically combined. For example a mixture of water and paraffin.
  • A compound, on the other hand, is a pure substance that is made up of two or more atoms of different elements that are chemically joined together.
  • Unlike an element which can not be broken by chemical means into simpler components, a compound can be chemically broken down to smaller substances such as smaller compounds or individual elements.
  • Sugar is an example of a compound that is made up of carbon, hydrogen and oxygen atoms.

According to the balanced chemical equation
Nadusha1986 [10]

Answer:

A) 15.5 mL

Explanation:

Given, Mass of oxalic acid = 0.3500 g

Molar mass of oxalic acid = 90.03 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{0.3500\ g}{90.03\ g/mol}

Moles\ of\ oxalic\ acid= 0.0038876\ mol

According to the given reaction:

5H_2C_2O_4_{(aq)}+2MnO_4^-_{(aq)}+6H^+_{(aq)}\rightarrow 10CO_2_{(g)}+2Mn^{2+}_{(aq)}+8H_2O_{(l)}

5 moles of oxalic acid react with 2 moles of potassium permanganate

Thus,

1 mole of oxalic acid react with 2/5 moles of potassium permanganate

0.0038876 mole of oxalic acid react with \frac {2}{5}\times 0.0038876 moles of potassium permanganate

Moles of potassium permanganate = 0.001555 moles

Also, considering:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity = 0.100 M

So,  

0.100=\frac{0.001555}{Volume\ of\ the\ solution(L)}

Volume = 0.01555 L

Also, 1 L = 1000 mL

So, volume = 15.5 mL
