By mixing 15.00ml of 0.800m HIO3 (pka = 0.77) with 45.00ml of 0.0200 m NaOh gives a pH = -0.32

The balanced acid-base reaction equation between iodic acid and NaOH is

HIO3 + NaOH -> H20 + NaIO3

What are the functions of buffer system?

In an aqueous solution, a weak Bronsted acid reversibly dissociates to produce weak conjugate bases and hydrogen ions.

The hydrogen ion molarity in the solution and the conjugate pair's molar ratio are related by the K an expression of the weak acid.

The molar ratio will be shifted more in favour of the weak conjugate base if a tiny amount of strong base is added to the weak acid solution. A buffer solution will be produced as a result of the pH of the solution shifting upward.

Hence the pH value is -0.32

Calculate the density of a solid in g/cm3 if it weighs 38.3 kg and has a volume of 0.00463 m3.

RideAnS [48]

Answer: D=8.27 g/cm³

Explanation:

Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.

$D=\frac{38.3kg}{0.00463m^3} *\frac{(1m)^3}{(100cm)^3} *\frac{1000g}{1kg}$

With this equation, the m³ and kg cancel out, and we are left with g/cm³.

D=8.27 g/cm³

What wave has the longer wavelength

natima [27]

The wavelength is the distance between one crest/trough to another crest/trough. On the image, it's basically the length between each peak of the wave. You can see that the distance between peaks in wave A are much shorter than the distance between the peaks in wave B.

Thus, wave B has the longer wavelength.

Liula [17]

The question is incomplete, here is a complete question.

An arctic weather balloon is filled with 27.8 L of helium gas inside a prep shed. The temperature inside the shed is 13 ⁰C. The balloon is then taken outside, where the temperature is -9 ⁰C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Be sure your answer has the correct number of significant digits.

Answer : The new volume of the balloon is 25.7 L

Explanation :

Charles's Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$
