Major species in the solution present in higher concentrations about more than 10% of the other species in the solution. The nature of solute that is dissolved in the solution, or the extent of reaction of different groups with the solvent decide the major species present in the solution.
For weak acids(bases) dissolved in water, the major species will be the undissociated acid(base) and water as the extent of dissociation of the molecular weak acid(weak base) is relatively less. For ionic solutes, the major species after dissolution in water will be the ions that form in the solution in addition to water.
Iron (II) iodide (FeI)is an ionic solute that is completely soluble in water. The following will be the reaction that represents solubility of FeI2 in water:
So, the major species when iron(II) iodide is dissovled in water will be
Answer: Species may become extinct because of changes in climate. competition with other species, a reduced food supply, or combinations of all of these. Most natural extinctions are isolated events that happen over a fairly long period of time
Explanation:
An extensive property is a property that depends on the amount of matter in a sample.
It is<u> true</u> that the moment of inertia of a hoop that has a mass and a radius is greater than the moment of inertia of a disk that has the same mass and radius.
Lower moments of inertia signify that only small forces are required to create a rotation, whereas higher moments of inertia mean that greater force must be used. The masses with the largest moment of inertia are those that reside furthest from the axis of rotation.
Due to the fact that a ring's center of mass is located on an axis that is perpendicular to its plane and passes through it, a ring has a higher moment of inertia than that of a circular disc of equal mass and radius. Because all of a ring's mass has been concentrated at the rim, which is furthest from the axis, which has a greater moment of inertia.
Therefore, the given statement is true.

Answer:
24.5g
Explanation:
Given parameters:
Mass of oxygen gas = 21.8g
Unknown:
Mass of water = ?
Solution:
This problem deals with the decomposition of water;
Reaction equation;
2H₂O → 2H₂ + O₂
2 mole of water will produce 1 mole of oxygen gas
First find the number of mole of the oxygen gas given;
Number of moles =
molar mass of O₂ = 2(16) = 32g/mol
Number of moles of O₂ = = 0.68moles
1 mole of oxygen gas will be produced from 2 mole of water
0.68moles of oxygen gas will be produce from 0.68 x 2 moles of water; = 1.36moles of water
Mass of water = number of moles x molar mass
Molar mass of water = 2(1) + 16 = 18g/mol
Mass of water = 1.36 x 18 = 24.5g
