<span>nuclear symbol consists of three parts: 1. the symbol of the
element; 2. the atomic number of the element;3. the mass of the element. for
the above problem, the symbol for potassium is k. it's atomic number is 40. the
number of protons is 19. so we denote this in the following nuclear symbol; 40
k 19</span>
Answer:
1.99 M
Explanation:
The molar mass of sodium thiosulfate (solute) is 158.11 g/mol. The moles corresponding to 110 grams are:
110 g × (1 mol/158.11 g) = 0.696 mol
The volume of solution is 350 mL = 0.350 L.
The molarity of sodium thiosulfate is:
M = moles of solute / liters of solution
M = 0.696 mol / 0.350 L
M = 1.99 M
taste bitter
have high pH's - more than 7
feel slippery
Explanation:
Bases are certain metallic oxides, metallic hydroxides and aqueous ammonia. They are substances that produces hydroxyl ions in solutions.
- The aqueous solutions of many bases have a bitter taste
- Bases generally have a soapy or slippery feel.
- They have a high pH reading on the scale.
- They are good electrolytes
- The are used for making soaps in industries.
