Noble gases

Explanation:

Electronic configuration 1s² 2s² 2p⁶

The element belongs to the group of the noble gases.

The noble gases have complete outer shell configuration of their atoms.
we can infer that the configuration above is for an element in the p-block because the last sub-level filled is the p-orbital.
The elements therefore belongs to the p-block
The block is from group 111A to O
Only the halogens and noble gases fits this picture from the option.
The outer most p-subshell have three orbitals requiring 6 electrons to fill them up.
This makes a complete and stable configuration.
The highest energy level of 2 is also made up of 8 electrons, an octet.
This is why we can conclude that they are noble gases.

Answer:

Iron remains = 17.49 mg

Explanation:

Half life of iron -55 = 2.737 years (Source)

$t_{1/2}=\frac {ln\ 2}{k}$

Where, k is rate constant

So,

$k=\frac {ln\ 2}{t_{1/2}}$

$k=\frac {ln\ 2}{2.737}\ year^{-1}$

The rate constant, k = 0.2533 year⁻¹

Time = 2.41 years

$[A_0]$ = 32.2 mg

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t

$[A_0]$ is the initial concentration

So,

$[A_t]=32.2\times e^{-0.2533\times 2.41}\ mg$

$[A_t]=32.2\times e^{-0.610453}\ mg$

$[A_t]=17.49\ mg$

<u>Iron remains = 17.49 mg</u>

Why do we use moles when calculating empirical chemical formulas, but not the mass?

Arada [10]

Answer:

because moles is the chemical unit*Avogadro's number, meaning it's the amount of atoms in the given unit.

How many atoms are there in 144g of sucrose, C12H22O11 or sugar molecules?

kati45 [8]

Answer:

2.53×10²³ atoms

Explanation:

To solve this, convert grams to moles and moles to atoms.

To convert grams to moles, use the molar mass of C₁₂H₂₂O₁₁ (342.296 g/mol). Divide the mass by the molar mass to get moles. Moles = 0.4207

To convert moles to atoms, use Avogadro's number (6.022×10²³ atoms/mol). Multiply moles by Avogadro's number to get atoms. Atoms = 2.53×10²³

Match the mixture with the substance// I really need help on this guys (it’s a pic btw)

koban [17]

Answer:

See below

Step-by-step explanation:

1. Colloid

B) Microscopic insoluble particles that are suspended throughout another substance.

Milk is a colloid. It consists of small fat globules suspended in water.

2. Emulsion

D) Two or more liquids that are not normally mixable.

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.

3. Solution

A) A solute that is evenly distributed within the solvent.

Sugar syrup is a solution of sugar in water.

4)Homogeneous

C) A mixture that has its components distributed evenly within the substance.

A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.
