B. Ca(OH)2 - (Calcium Hydroxide)
Answer:
A solution of sugar that contains the maximum amount of sugar that will dissolve is a saturated solution.
Explanation:
A saturated solution is a solution that contains as much solute as can dissolve in a given solvent at a given temperature.
for you the solute is sugar
Answer:
Salts can be several different colors and may be any of the five tastes, including salty, sweet, bitter, sour or savory. Their odor depends on the acid and base it is comprised of. Salts comprised of strong acids and bases, called strong salts, are odorless.
Answer:
The ice will not melt
Explanation:
Given:
Mass of chunk = 0.25 g
moles of sodium = mass / molar mass = 0.25 / 23 = 0.010 g
ΔH = -368 KJ
Hence, 2 moles of Na produced 368 KJ
So 1 mole will produce 368 / 2 KJ and 0.01 mole will produce
= (368 / 2) * 0.01 = 2.0056 KJ
Also, moles of ice = mass / molar mass of water = 50 / 18 = 2.8 g
Energy required to melt the ice = enthalpy of fusion of ice * number of moles of ice
= 6.01 * 2.8 = 16.722 KJ
But we have 2.0056 KJ, so the ice will not melt.
<span>The answer to this would be radioactive decay. This is also known as "nuclear decay" or "radioactivity".</span>
