Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field
Answer:
Explanation:
Hello,
Based on the given reaction, since magnesium and water are in a 1:2 molar ratio at the reactants, we must apply the following stoichiometric factors to compute the complete reaction of the 6.0 g of magnesium:
Best regards.
Answer:
0.2 mol
Explanation:
Use the given values to find the molar mass. The molar mass is 40 g/mol.
23 + 16 + 1 = 40
Using the molar mass, convert grams to moles.
(8 g)/(40 g/mol) = 0.2 mol
You have 0.2 mol of sodium hydroxide.
Answer:
An acid is a substance that when dissolved in water produces hydroxonium ion as the only positive ion in water
Explanation:
HCL +H20=H3O + CL
Salt can dissolve in water because it is an ionic compound. The Na⁺ and Cl⁻ ions get solvated by the water molecules and leave the surface of the crystal;
The formula of ethanol is CH₃CH₂OH. Ethanol can dissolve in water because its OH group can form strong hydrogen bonds to the water molecules.
