<span>To determine the balanced chemical equation, it is necessary to identify the symbols and charges for each element and then balance the equation. This results in:
Al(OH)3(aq) + 3HBr(aq) ---> AlBr3(aq) + 3H2O(l)
The net ionic equation involves summing the charges and breaking them down into fundamental parts.
Al3+ + 3OH- + 3H+ + 3Br- --> Al3+ + 3Br + H3O+
After eliminating aluminum and bromine, we have:
3OH-(aq) + 3H+(aq) --> 3H2O(l)</span>
The aqueous solution of Na3PO4 is described as "strongly basic."
Answer: These celestial bodies are composed of rock or gas and are named after ancient deities.
Explanation:
Earth is the THIRD planet from the Sun and is capable of sustaining life for various organisms.
VENUS ranks as the second planet in our solar system and derives its name from the Roman goddess associated with love and beauty.
MARS, the fourth planet, gets its name from the Roman goddess of war.
Hence, Venus and Mars are NEIGHBORS to EARTH.
Answer:
The categorization of strong, weak, and non-electrolytes is detailed below, based on the examples presented in the question.
Explanation:
A strong electrolyte fully dissociates or nearly so in an aqueous environment; typically, strong acids, bases, and salts fall under this category. Examples of strong electrolytes include:
- Hydrochloric acid, HCl
- Calcium hydroxide, Ca(OH)2
- Potassium chloride, KCl
A weak electrolytepartially ionizes in solution; weak acids and bases are primary instances. Examples consist of:
- Methylamine, CH3NH2
- Hydrofluoric acid, HF
A non-electrolytedoes not dissociate in an aqueous medium. Examples of non-electrolytes are:
- Sucrose, C12H22O11
- Methanol, CH3OH
Solution:
Molality measures the concentration of a solute in a solution, defined by the amount of solute per specific mass of solvent.
Thus,
Molality = moles of solute / kg of solvent.
Therefore, kg of solvent = moles of solute / molality.
moles of solute = mass / molar mass
= 25.31 g / 101.1 g/mole
= 0.2503 mole.
kg of solvent = 0.2503 mole / 0.1982 m
= 1.263 kg
= 1263 g.
This is the final answer.
