<span>The answer is "his conviction and execution should be upheld". Frank Palko was first charged with murder and claimed that Connecticut violated the Double Jeopardy Clause of the Fifth Amendment. The fifth amendment states that "there must be no person to be put twice in jeopardy of life and limb" so this was the violation the court made after they charge him with murder for the second time. That's why when the second trial was made,he was sentenced to by the Supreme court which decided that he should be executed and convicted because of the evidences found.</span>

How many milliliters of a 0.266 M RbNO3 solution are required to make 150.0 mL of 0.075 M RbNO3 solution? How many milliliters o
Westkost [7]

Answer : 42.3 ml of a 0.266 M RbNO_3 solution are required.

Solution : Given,

Molarity of RbNO_3 solution 1 = 0.266 M

Molarity of RbNO_3 solution 2 = 0.075 M

Volume of RbNO_3 solution 2 = 150 ml = 0.150 L      (1 L = 1000 ml)

Formula used :

M_1V_1=M_2V_2

where,

M_1 = Molarity of RbNO_3 solution 1

M_2 = Molarity of RbNO_3 solution 2

V_1 = Volume of RbNO_3 solution 1  

V_2 = Volume of RbNO_3 solution 2

Now put all the given values in above formula, we get

0.266M\times V_1=0.075M\times 0.150L\\V_1=0.042293L=42.293ml\approx 42.3 ml                 (1 L = 1000 ml)

Therefore, 42.3 ml of a 0.266 M RbNO_3 solution are required.

A chemist adds 405.0mL of a 0.79M sodium carbonate solution to a reaction flask. Calculate the millimoles of sodium carbonate th
Sophie [7]

Answer:

320 mmol

Explanation:

405.0 mL * 1L/1000 mL = 0.4050 L

0.79 M = 0.79 mol/L

0.79 mol/L * 0.4050 L=0.32 mol

0.32 mol * 10^3 mmol/1 mol = 320 mmol

What is the bronsted acid of NO2- + H2O HNO2 + OH-​
sammy [17]
<h3><u>Answer</u>;</h3>

H2O -Bronsted Acid

<h3><u>Explanation;</u></h3>
  • Bronsted-Lowry acids are  H+ donors , while Bronsted-Lowry bases are H+ acceptors .
  • A reaction of a Bronsted-Lowry acid and a Bronsted base is a neutralization reaction that is characterized by H+ transfer.
  • The above reaction is an example of base ionization or dissociation where;

                 B (aq) + H2O (l) → BH+ (aq) + OH– (aq)

          That is; Base + Acid will give a conjugate acid + hydroxide ion

  • In our case; NO2- + H2O → HNO2 + OH-​ ; H2O is the H+ donor and thus, it is a Bronsted Acid.
