Answer:
66.0 mL HClO3
Explanation:
M1V1 = M2V2
M1 = 0.100 M HClO3
V1 = ?
M2 = 0.165 M KOH
V2 = 40.0 mL KOH
Solve for V1 --> V1 = M2V2/M1
V1 = (0.165 M)(40.0 mL) / (0.100 M) = 66.0 mL HClO3
It helps frame the idea that citizen ship requires being actively involved in civic life.
Use equation:
PV = nRT
1.4*V = 1*0.082057*332
V = 27.24/1.4
V = 19.46L
Molar mass H2S = 2+32 = 34g/mol
34g H2S has volume 19.46L
Density = mass / volume = 34/19.46 = 1.75 g/L
Answer:
conductors of electricity when in liquid or aqueous state
high melting point
soluble in water
Explanation:
An ionic substance is any substance that is composed of two ions of opposite charge.
In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.
All ionic substances have a very high melting point and dissolve in water easily.
We are given with a mixture of sand and table sugar. The mixture has a mas s of 3.84 grams. After recovery, it was found out that there is 1.43 grams of sand. The amount of table sugar then is 3.84-1.43 or 2.41 grams. This is equal to 2.41/3.84 or 62.76% by mass/
