Answer:

Option a

Explanation:

a) $I^-$

Atomic number of I = 53

No. of electrons = atomic number + no. of negative charge

= 53 + 1 = 54

Atomic number of Xe = 54

In a neutral atom, no. of electron is equal to no. of protons.

So. no. of electron in Xe = 54

a) $Ba^{2+}$

Atomic number of I = 56

No. of electrons = atomic number - no. of positive charge

= 56 - 2 = 54

All the species in the set a have 54 electrons.

The air in a balloon with a volume of 25.0 liters is heated from 20° C to 60° C. If the pressure stays the same, what will be th

Nesterboy [21]

Answer:

New volume of the balloon will be 28.4 L.

Explanation:

As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:

$\frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}$

where $V_{1}$ and $V_{2}$ are volume of gas at $T_{1}$ and $T_{2}$ temperature (in kelvin scale) respectively.

Here $V_{1}=25.0L$ , $T_{1}=(273+20)K=293K$ and $T_{2}=(273+60)K=333K$

So $V_{2}=\frac{V_{1}T_{2}}{T_{1}}=\frac{(25.0L)\times (333K)}{293K}$ = 28.4 L

So new volume of the balloon will be 28.4 L.

How could the combustibility of a substance influence how the substance is used?

11111nata11111 [884]

Answer:

Combustibility is a measure of how easily a substance bursts into flame, through fire or combustion. This is an important property to consider when a substance is used for construction or is being stored. It is also important in processes that produce combustible substances as by product

If you mix cu2+ with? a. nacl, b. nano2, c. h2o , arrange the solutions based on their absorption from highest frequency to lowe

erica [24]

The arrangement of the solutions based on their absorption from highest frequency to lowest frequency :

b. $NaN$ $O_{2}$ > c. $H_{2} O$ > a.NaCl

<h3>What is absorption frequency?</h3>

The frequency of the molecular vibration that led to the absorption is the same as the absorption frequency of a basic IR absorption band.

In a way, an emission spectrum is the opposite of an absorption spectrum.
The discrepancies in the energy levels of each chemical element's orbitals correspond to absorption lines for each chemical element at various particular wavelengths.
Therefore, it is possible to identify the constituents in a gas or liquid using its absorption spectrum.
Absorption spectroscopy is most frequently used to measure infrared, atomic, visible, ultraviolet (UV), and x-ray waves.
