Yes it can be but if stuff like the council have the equipment to pay for to help stop erosion then it wouldn't be as bad
Out of the three you gave ecosystem is what I would call the most broad. An ecosystem includes living AND non-living things in an area
Community is all the LIVING things in an area (plants are included and I think bacteria is too, but I'm not sure)
Population is pretty narrow it just looks at specific species in one area. Population of mosquitoes doesn't include butterflies, if only looks at mosquitoes
Hope this helped!
Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
Answer:
0.036 × 10²³ oxygen atoms
Explanation:
Given data:
Mass of compound = 0.24 g
Number of oxygen atoms = ?
Solution:
First of all we will calculate the number of moles of compound.
number of moles = mass/ molar mass
Number of moles = 0.24 g/ 100.1 g/mol
Number of moles = 0.002 mol
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole of CaCO₃ contain 3 moles of oxygen atom.
0.002 mol × 3 = 0.006 moles of oxygen atoms.
Number of oxygen atoms:
1 mole = 6.022 × 10²³ number of oxygen atoms
0.006 mol × 6.022 × 10²³ f oxygen atoms / 1 mol
0.036 × 10²³ oxygen atoms
