<u>Answer:</u> The isotopic representation of tritium atom is _1^3\textrm{H}

<u>Explanation:</u>

Isotopes are defined as the chemical species which have same atomic number but differ in mass number.

Hydrogen has 3 isotopes that occur naturally. They are: H-1 (protium), H-2 (deuterium) and H-3 (tritium)

The isotopic representation of an atom is: _Z^A\textrm{X}

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

We know that:

Mass number of H-3 isotope = 3

Atomic number of H-3 isotope = 1

Hence, the isotopic representation of tritium atom is _1^3\textrm{H}

Answer:

₁H³

Explanation:

Tritium is the isotope of hydrogen.

It consist of one proton two neutron and one electron.

It is rare isotope of hydrogen.

It is radioactive.

Its mass is  3.0160492 u.

In atmosphere it is also present in trace amount.

Its decay product is He³.

₁H³  →  ³He₂⁺¹ +  e⁻

IgorLugansk [536]
<h2>Answer:</h2>

In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.

As kinetic energy is directly proportional to temperature.

To make the kinetic energy of the molecules equal she should:

  • Heat one glass of 25°C to 40°C.

               or

  • Cool the juice of 40°C to 25°C

What is the pH of a solution has a hydrogen ion concentration of 6.3 x 10–10 M? Show work
NISA [10]

Answer:

pOH = 4.8

pH = 9.2

Explanation:

Given data:

Hydrogen ion concentration = 6.3×10⁻¹⁰M

pH of solution = ?

pOH of solution = ?

Solution:

Formula:

pH = -log [H⁺]

[H⁺] = Hydrogen ion concentration

We will put the values in formula to calculate the pH.

pH = -log [6.3×10⁻¹⁰]

pH = 9.2

To calculate the pOH:

pH + pOH = 14

We will rearrange this equation.

pOH = 14 - pH

now we will put the values of pH.

pOH = 14 - 9.2

pOH = 4.8
