Please answer quick 2. Imagine you have two beakers. Both beakers are filled with the same amount of water. The water in both beakers is the same temperature as well. You add 50 g ofSubstance A to the first beaker, and 50 g of Substance B to the second beaker. After stirring both beakers, there is a small pile Substance A at the bottom of the first
beaker. None of Substance B is visible in the second beaker. Which of the following statements is true?
A. Substance A is less soluble in water than Substance B.
B. Substance A is more soluble in water than Substance B.
C. Substance A is not soluble in water,
D. Substance B is not soluble in water,

A. Substance A is less soluble in water than Substance B.

Explanation:

Solubility: The term "solubility" is described as a specific property determining the capability of a particular solute, substance to get dissolve in a "solvent". Thus, solubility is being measured with respect to the "maximum amount" of a specific solute that is dissolved or mixed in a solvent at "equilibrium". After the given process, the resultant solution is referred to as a saturated solution.

In the question above, the correct answer is option-A.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
