deff fn [24]3 years ago
5 0

Answer:4.42 g= 1 mol/55.845 =.079 moles of Fe

Explanation:Given 4.42 grams of Fe. The atomic weight of Fe(iron) found on the periodic table is 55.845. Divide grams by the atomic weight to convert to moles.

castortr0y [4]

Answer:

liquid and solid

Explanation:

Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are  three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.  

This discovery took place with the help of artificial intelligence of today's world which is transforming the world  day by day.

The State is considered to be true as it is thermodynamically stable state of the matter.

When a nonmetal oxide reacts with water, it forms an oxoacid with the same oxidation number as the nonmetal. Give the name and f

Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid (HClO)

What are Transition metal oxides ?

Transition metal oxides (TMOs) are another class of nanomaterials, frequently used as anode in alkaline batteries due to their distinctive properties such as abundant active sites, short diffusion pathways, low preparation cost, high theoretical capacity and distinct reaction mechanism.

Cl2 + H2O ⇌ HClO + HCl

Cl2 + 4 OH− ⇌ 2 ClO− + 2 H2O + 2 e−

Cl2 + 2 e− ⇌ 2 Cl−

The acid can also be prepared by dissolving dichlorine monoxide in water; under standard aqueous conditions, anhydrous hypochlorous acid is currently impossible to prepare due to the readily reversible equilibrium between it and its anhydride.

2 HClO ⇌ Cl2O + H2O      K (at 0 °C) = 3.55×10−3 dm3 mol−1

The presence of light or transition metal oxides of copper, nickel, or cobalt accelerates the exothermic decomposition into hydrochloric acid and oxygen

2 Cl2 + 2 H2O → 4 HCl + O2

<h3> <u>ANSWER</u> </h3>

4. O²-

<h3><u>EXPLANATION</u> </h3>

O²- has 16 electrons while Ne has 18 electrons. O²- is a molecule that has one electron added to each atom, meaning that there are two extra electrons which makes O²- the same electron configuration as of Ne atom.
