3. When 0.275 moles of Strontium metal and hydrochloric acid that contains 0.750 mol of HCl are combined they react to completion according to the equation below. How many liters of hydrogen gas, are produced at standard temperature and pressure (STP)?

Sr(s) + 2HCl(aq) → SrCl2(aq) + H2(g)

Dealing with the stability of a protein i found in lab that the basic pH, the protein folded based on my results. However, how can it destabilize a proteins structure? Does it have to do with the temperature as well in the high pH?

In JAVA

• Write a program that calculates the average of a group of test scores, where the
lowest score in the group is dropped. It should use the following methods:
• int getScore() should ask the user for a test score, store it in a reference
parameter variable, and validate it. This method should be called by main once
for each of the five scores to be entered.
• void calcAverage() should calculate and display the average of the four highest scores.

This method should be called just once by main, and should be passed
the five scores.
• int findLowest() should find and return the lowest of the five scores passed to it.
It should be called by calcAverage, which uses the method to determine one of
the five scores to drop.
The program should display a letter grade for each score and the average test
score.
Input Validation: Do not accept test scores lower than 0 or higher than 100.

*******(use random numbers 50-100. Don't ask the user to enter data)
********Show all test scores, the one that got dropped and the average.

*******For random numbers, use the Random class not Math.random()

If a pure R isomer has a specific rotation of -137.0 degrees and a sample contains 84.0% of the R siomer and 16.0% of it anantiomer, what is the observed specific rotation of the mixture?

Max is a 18 year old college student with insulin-dependent diabetes mellitus (Type 1). Recently, Max has been staying up late to study for final exams. Last night while studying, he shared a full box of cupcakes with his friend. Overnight Max woke up feeling thirsty and in need of urinating. Upon awakening to get ready to take his exam, he tells his friend that he is feeling light headed and his heart is racing. While brushing his hair, he realizes his legs are wobbly; and he panics realizing he forgot to take his insulin yesterday. He calls out to his friend, who finds him in the bathroom unconscious. He is transported by ambulance to the nearby emergency department. Below are the result of his physical and laboratory tests. Physical Exam and Laboratory Values Heart Rate 135 bpm Respirations 32/minute; slow and deep Blood Pressure 90/40 Plasma Levels Glucose 540 mg/dl Na+ 134 mEq/L (normal = 140 mEq/L) K+ 5.8 mEq/L (normal = 4.5 mEq/L) Cl- 96 mEq/L (normal = 105 mEq/L) HCO3- 8 mEq/L (normal = 24 mEq/L) Ketones ++ (elevated) Urine Glucose 4+ (normal = none) Arterial Blood Arterial Blood - PO2 110 Hg (normal = 100 mm Hg) Arterial Blood - PCO2 20 mm Hg (normal = 40 mm Hg) Arterial Blood - pH 7.22 (normal = 7.4)

Briefly describe the change from the current and prior years in each of these key areas and determine if the changes would be positive or negative from an investor / stockholder’s view.

Complete and balance the following equations, and identify the oxidizing and reducing agents. (Use the lowest possible coefficients. Include states-of-matter (s), (l), (g), (aq) similar to the given reaction.)
(a) MnO4-(aq) + Cl-(aq) ? Mn2+(aq) + Cl2(g) (acidic solution)
Balanced equation:16H+(aq)+2MnO4-(aq)+10Cl-(aq) ? 2Mn2+(aq)+5Cl2(g)+8H2O(l)
oxidizing agent:   MnO4-Correct.
Reducing agent: Cl- Correct

(b) I2(s) + OCl-(aq) ? IO3-(aq) + Cl-(aq) (acidic solution)

oxidizing agent:OCl- Correct
reducing agent:I2 Correct

(c) Cr2O72-(aq) + I-(aq) ? Cr3+(aq) + IO3-(aq) (acidic solution)
Balanced equation
oxidizing agent  
reducing agent

(d) Pb(OH)42-(aq) + ClO-(aq) ? PbO2(s) + Cl-(aq) (basic solution)
Balanced equation

reducing agent

Just starting to get really frustrated with these. I know how to do them (I completed the first one without much issue) but cannot get the rest of them. I don't know what it is that I'm missing/doing wrong. will give addition points for the correct answer as well as good work. Thank you in advance!!!
