Answer:
the mass is of potassium is 88.38 rounded to the nearest hunndred.
Explanation:
Answer:
K2CO3 and NaF
Explanation:
In order to ascertain which salt would form a basic solution we have to identify the classification of each of the salts.
- NH4Br: is the salt of a weak base (NH3) and a strong acid (HBr). This means that it would form an acidic solution.
- Pb(NO3): This is a normal salt, hence would not form a basic solution.
- K2CO3: This is salt that forms a strongly alkaline/basic solution.
- NaF: it is the salt of a strong base, NaOH, and a weak acid, HF. This means this would form a basic solution.
They are both changing how they look, feel, and they have a chemical change because you can’t fix decomposing wood or rust without breaking it physically.
Given :
0.26 mole of 
and 0.35 L of water.
To Find :
The molarity of a solution of made by mixing 0.26 mole of potassium
phosphate with water up to 0.35 L .
Solution :
We know, molarity is given by :
Therefore, the molarity of solution is 0.743 M.
Alkalis are based that when dissolved in water produce OH- ions
Bases react with acids to give water and salt
