In the sentence argon has several properties distinct from other gases", what does distinct mean?
a)making a clear imression
b)notable
c)separate
d)easily seen
who ever answers i will give brainiest and 100 points!

Distinct means separate.  

Option: C  

Explanation:

From the given sentence Argon has several properties that are separate from other gases. This sentence refers that Argon gas has many properties that are different from other gases.

The things are distinct from one another, they are different. Although, the solubility of oxygen is same as Argon. Argon is soluble in water in the form of nitrogen. This gas is isolated through the liquid air fractionation only 0.94% argon is present in the atmosphere.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
