Answer:

IO_4^-= Periodate\ ion

IO_3^-= Iodate\ ion

IO_2^-= Iodite\ ion

IO^-= Hypoiodite\ ion

Explanation:

Oxyanions:

Oxyanions are anions that have one or more oxygen atoms bonded to another elements is called oxyanions.

General formula of oxyanions are : A_xO_y^{z-}

Where, A represents an element and O represents oxygen atom.

Four most common oxyanions of Iodine are:

IO_4^-= Periodate\ ion

IO_3^-= Iodate\ ion

IO_2^-= Iodite\ ion

IO^-= Hypoiodite\ ion

At a pressure of 650 kpa 2.2L of hydrogen is used to fill a balloon to a final pressure of 115 kpa. What's the balloons volume?
Alborosie

Answer:

V₂ = 12.43 L

Explanation:

Given data:

Initial pressure = 650 KPa

Initial volume = 2.2 L

Final pressure = 115 KPa

Final volume = ?

Solution:

The given problem will be solved through the Boyles law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

650 KPa ×2.2 L = 115 KPa × V₂

V₂ = 1430 KPa. L/ 115 KPa

V₂ = 12.43 L

stealth61 [152]

d) T3 and T4. T3 and T4 are poorly soluble in water, and more than 99% of the T3 and T4 circulating in blood is bound to carrier proteins. The main carrier of thyroid hormones is thyroxine-binding globulin, a glycoprotein synthesized in the liver.

An isotope of carbon has 8 neutrons. What is the correct hyphenated symbol for this isotope?
Rom4ik [11]

Answer:

Carbon-14 or C-14

Explanation:

Since the isotope is a carbon isotope, it means the the atomic number of the isotope is 6.

The atomic number of an element is the proton number.

Therefore, the isotope has a proton number of 6

Now we need to obtain the mass number of isotope in order to write the symbol of the isotope. This is illustrated below:

Mass number = Proton +Neutron

Proton = 6

Neutron = 8

Mass number = 6 + 8

Mass number = 14

Therefore, the symbol of the isotope is carbon-14 or C-14

Calculate the molarity of 6.631 g NANO3 in 100.0 mL of solution<br><br><br>add stepss
riadik2000 [5.3K]

Answer:

0.7802 M

Explanation:

<u>Data:</u>

  • V (volume) = 100.0 mL → V = 0.1000 L
  • m (mass) = 6.631 g → n = 0.07802 mol

<u>Wanted: </u>

  • M (Molarity)

<u>Equation: </u>

M = \frac{mol}{L}

<u>Solution:</u>

1. Convert mL to L:

  • V = 100.0 mL x \frac{1 L}{1000 mL} = 0.1000 L

2. Convert g to mol:

  • n = \frac{6.631 g}{84.9947 g/mol} = 0.07802 mol

3. Molarity Equation:

  • M = \frac{0.07802 mol}{0.1000 L} = 0.7802 M
