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

Answer:
16.499 × 10∧ 21 atoms
Explanation:
Given data:
mass of P2O5= 0.560 g
number of atoms= ?
first of all we will calculate the molar mass of P2O5:
P = 2×31 g/mol = 62 g/mol
O = 5× 16 = 80 g/mol
molar mass of P2O5 = 142 g/mol
Noe we will find the moles of 0.560 g P2O5:
moles = mass / molar mass
moles = 0.560 g/ 142 g/mol
moles = 0.0039 mol
now we will find the atoms present in 0.0039 moles:
0.0039 × 6.02 × 10∧ 23 molecules
2.357 × 10∧ 21 molecules
P2O5 consist of 7 atoms:
2.357 × 10∧ 21 × 7 = 16.499 × 10∧ 21 atoms
No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
Magnesium ribbon dissolves in zinc nitrate and copper nitrate solutions.
Even though the question is incomplete and refers to your practical work, however, I will try to help you as much as I can.
Metals dissolves in solutions of other metals that are lower than them in the electrochemical series. Hence, copper strip will show no change in magnesium nitrate or zinc nitrate solution. A zinc strip will not show any change in magnesium nitrate or zinc nitrate.
However, a magnesium ribbon will dissolve very quickly in zinc nitrate and copper nitrate solutions.
