Use the following structures of amino acids to answer the questions below. Note that the difference in the structures (the side

chains) is highlighted by gray shading.
A student performed chromatography of the four amino acids and the results were shown in the chromatogram below. If an anion exchange column (column is positively charged) was used in a neutral buffer, assign each amino acid to the corresponding peak in the chromatogram.

why is the concentration of helium increased in some gas mixtures that divers breath in order to reduce the partial pressure of
sdas [7]

Answer:

Because of oxygen toxicity.

Explanation:

Oxygen toxicity.

Oxygen has been known to cause central nervous system (CNS) toxicity when the pressure gets higher. This toxicity can cause convulsions, and this can cause the diver to drown.

The current standard maximum safe oxygen working pressure is 1.4 atm ppO2. This is equal to 56.5m/185′ when breathing air (21% O2 / 79% N). Below that depth the fraction of oxygen in a breathing gas must be reduced, and in order to maintain this maximum pressure of 1.4 ppO2, Helium must be added.

Sometimes Combination reaction takes place sometimes decomposition and sometime replacement.. Can someone say me the conditions
Rina8888 [55]

Whenever any substance goes under chemical change so any of the reaction will happen either both or multiple compounds will combine to produce combination reaction either one compound will decompose itself into 2 or more compounds or elements and last one is replacement reaction the either reaction is not even going to combination nor decomposition, So when a reaction like that happens it must replacement reaction.

Now the question is what's the condition required for it, so basically a chemical reaction when takes place it depends upon several factor on the basis of which we conclude products. The factors are Temperature,catalyst,reagents, either what is the mechanism of reaction, stability of reactants and stability of products and alot more.

During reaction sometimes gas forms and sometimes not yea and well that also depends on the chemical reactivity and stability of product sometimes product found itself most stable releasing the gas evolving so it's been done itself and sometimes we add catalyst and adjust the reaction to extract that gas and get desirable product manually.

I wrote all i know if sorry if this is not what you're looking for :(

Zn + H2SO4 ZnSO4 + H2<br><br> The mole ratio of zinc to zinc sulfate is
ValentinkaMS [17]

Answer:

Ratio is 1:1

Explanation:

I do not see any coefficients infront of the reactants and the products, therefore, we can automatically assume that every reactant and product is 1 mole. Don't get confused by the 4 off the O. It just means that 1 mole of sulfate has 1 zinc and 4 oxygens.
