Answer:

H₁ = 1s¹

He₂ = 1s²

Explanation:

Electronic configuration of hydrogen.

H₁ = 1s¹

Electronic configuration of helium.

He₂ = 1s²

The helium consist of complete out most electronic shell configuration and stable. While hydrogen consist of one electron in 1s sub shell.

Properties of hydrogen:

1. Its atomic number is one and mass is 1 g/mol.

2. It is non metal.

3. It is colorless and odorless gas.

4. Hydrogen can gain or lose the one electron from and form a compound while helium is non reactive.

5. At high temperature its snow like crystals are formed.

Properties of helium:

1. Its atomic mass is 4 g /mol and atomic number is 2.

2. It is inert gas

3. It is colorless and odorless gas.

4. It has low density and low, low boiling point and low solubility.

5. It was the first gas used in the filling of balloons.

Which list includes three forms of energy?(1) chemical, mechanical, electromagnetic(2) chemical, mechanical, temperature(3) ther

bekas [8.4K]

The capacity to do work is said to be energy. It is a quantitative property and conserved quantity. It can exist in different forms such mechanical energy, sound energy, chemical energy etc. According to law of conservation of energy, energy can neither be created nor be destroyed implies there is no loss of energy occurs during any process or any reaction only conversion of energy takes place.

Temperature and pressure are not forms of energy, they are physical properties.

Hence, first option (1) is the correct answer i.e. chemical, mechanical, electromagnetic are three forms of energy.

A solution has a pH of 2.5. what is the H+

romanna [79]

<u>Answer: </u>The concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

$pH=-\log [H^+]$ .....(1)

We are given:

pH of solution = 2.5

Putting values in equation 1, we get:

$2.5=-\log [H^+]$

$[H^+]=10^{-2.5}$

$[H^+]=3.16\times 10^{-3}M$

Hence, the concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

What ions and/or molecules (apart from water) are present in relatively large proportions in a solution of a weak acid hclo (aq)

matrenka [14]

HClO, perchloric acid is a weak acid. Unlike strong acids like HCl or H2SO4 it not dissociate completely but partially such that an equilibrium exists between the dissociated ions and the undissociated acid. The equilibrium is as shown below:

HClO + H2O ↔ H3O⁺ + ClO⁻

Since HClO is a weak acid, the reverse reaction is favored over the forward reaction. Thus apart from water, HClO will be present in large amounts.
