1 answer:

5 0

Each row of the periodic table is called a period and each column of the periodic table is called a group (or family). Some groups have specific names like the halogens or noble gases. Elements within the same period or group have similar properties

Answer:

$KOH + H_2SO_4 \rightarrow K_2SO_4 + H_2O$

Explanation:

A chemical reaction describes the reaction between reactants to produce products.

A chemical equation is represented as a reactant present on the left-hand side of the equation if two or more reactants are present they are separated by the "plus" sign.

On the right side of the equation product is written and if more than one product is formed then these are separated by "plus" sign as in the reactants.

The reactant and the products are separated by an arrow, the head of arrow is in the direction of the product when the reaction is irreversible.

In the case of reversible reactions or chemical reactions that are present in equilibrium, the reactant and product are separated by a double-headed arrow.

Use the given relationship to calculate the ionization energy of a thallium atom, given that radiation of 58.4 nm produces elect

Elenna [48]

The ionization energy is 1 × 10^-18 J

<h3>What is ionization energy?</h3>

The ionization energy is the energy required to remove an electron from an atom.

We have the following information;

wavelength of the photon = 58.4 nm

Speed of the electron = 2310 × 10^3 m/s

Since;

hv = I + 1/2mv^2

v = c/λ

hc/λ = I + 1/2mv^2

I = hc/λ - 1/2mv^2

I = (6.6 × 10^-34 × 3 × 10^8/58.4 × 10^-9) - (1/2 × 9.11 × 10^-31 × (2310 × 10^3)^2)

I = 1 × 10^-18 J
