What else can I help you with?
Ammonia is always evolved when an ammonium salt is heated into a basic solution?
No, ammonia is only evolved when an ammonium salt is heated with a strong base, such as sodium hydroxide. This reaction occurs because the strong base deprotonates the ammonium ion, leading to the formation of ammonia gas.
True or false The concentration of an acid or base refers to how completely it dissociates in water?
False. The concentration of an acid or base refers to the amount of the acid or base present in a given volume of solution, while the extent of dissociation refers to how completely the acid or base breaks apart into ions in water.
What is always true about a strong base?
A strong base will always completely dissociate in water to produce hydroxide ions. Strong bases have a high pH and are able to accept protons from acids to form water.
What is always true pf a weak base?
A weak base will always partially ionize in solution and generate fewer hydroxide ions compared to a strong base. This means that a weak base will have a lower pH compared to a strong base at the same concentration. Weak bases also have higher Kb values compared to strong bases.
Is it possible to have a concentrated solution of a weak acid or base True or False?
True. It is possible to have a concentrated solution of a weak acid or base, as the concentration of a solution refers to the amount of solute dissolved in a solvent, regardless of the strength of the acid or base. The degree of dissociation may be low, but the concentration can still be high.
Ammonia is always evolved when an ammonium salt is heated into a basic solution?
No, ammonia is only evolved when an ammonium salt is heated with a strong base, such as sodium hydroxide. This reaction occurs because the strong base deprotonates the ammonium ion, leading to the formation of ammonia gas.
Is it true that nitrogen is not used to make ammonia and nitric acids?
No, this is false.
Is it true or false that two triangles are a cylinders base?
false. the base of a cylinder is a circle.
The base angles of an isosceles trapezoid are not congruent true or false?
False
How does the presence of a false conclusion in a strong argument indicate that not all of its premises can be true?
The presence of a false conclusion in a strong argument suggests that at least one of its premises must be false, as a strong argument should lead to a true conclusion based on true premises.
A coalition of political parties can be strong or weak true or false?
true
Is it true or false a right circular cone can have triangle as a base?
It is false. If it has a triangle as its base it would be a pyramid.
The base level is the theoretical limit to downcutting True or false?
true
If you want to identify a base you feel it is that true or false?
that is dangerous. so its false
Do cones and prisms both have only one base true or false?
False
True or false the heart is a strong and specialized muscle?
the heart is an organ so false
True or false the dixiecrats were strong supporters of Truman's civil rights policies?
false
