Answer:

What is the chemical composition of iodized salt?

Iodized salt is a very cheap and good way of getting the necessary iodine. Ordinary table (cooking) salt is a chemical compound called "sodium chloride" (its chemical formula is NaCl). "Sodium iodide" (NaI) is added to the NaCl to make iodized salt.

Salt that has been iodized contains trace levels of sodium or potassium iodide. It's just regular salt sprinkled with potassium iodate. It has the same appearance and flavor! The bulk of table salt used currently is iodized, which has a number of advantages.

function of iodized salt
Iodized salt aids in the production of hormones that control heart rate and blood pressure. It also aids in the burning of unwanted fat deposits that may lead to heart disease. Salt maintains a healthy amount of hydration and electrolyte balance.

Based on its type of chemical bond, which substance has the highest boiling point?
Ber [7]
Answer: Lithium Fluoride

Explanation: Let’s see,,,
1. Obviously not hydrogen or carbon dioxide because they’re gas at room temp.
2. Lithium Fluoride is an ionic compound which means they have higher intermolecular forces and require more energy to break them, so it probably has a higher boiling point.

15.5 g of an unknown metal at 165.0°C is dropped into 150.0mL of H2O at 23.0°C in a coffee cup calorimeter. The metal and H2O re

Answer:

Specific heat capacity of metal is 2.09 j/g.°C.

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Given data:

Mass of metal = 15.5 g

Initial temperature = 165.0°C

Initial temperature of water = 23.0°C

Final temperature = 30.0°C

Specific heat capacity of metal = ?

Specific heat capacity of water = 4.184 J/g°C

Volume of water = 150.0 mL or 150.0 g

Solution:

Formula:

- Qm  =  +Qw

Now we will put the values in formula.

-15.5 g × c × [ 30.0°C - 165.0°C] = 150 g × 4.184 J/g°C × [ 30.0°C - 23.0°C]

15.5 g × c × 135°C = 4393.2 j

2092.5 g.°C  × c = 4393.2 j

c = 4393.2 j/2092.5 g.°C  

c = 2.09 j/g.°C

When a 10 mL graduated cylinder is filled to the 10 mL mark, the mass of the water was measured to be 9.925 g. If the density of
Vlada [557]
Measured volume = 10 ml 
mass = 9.925 g 
density = 0.9975 g/ml
density = \frac{mass}{volume} 
so actual volume = \frac{mass}{density} = \frac{9.925}{0.9975} = 9.95 mL
Percentage Error = \frac{measured volume - Actual volume}{actual volume} x 100 
= \frac{10 - 9.95}{9.95} x 100 = 0.5 % error

The electron configuration belonging to the atom with the highest second ionization energy is ________.
Gemiola [76]

Answer:

Element Lithium

Explanation:

The element with the highest second ionization energy is lithium. It belongs to the alkaline metal group I.e group one metals

It has the highest second ionization energy because it is very difficult to remove the electron from the 1s orbital.

Its atomic number is 3. The electronic configuration is 1s2 2S1
