8 0

Answer:

A good society has a transparent talk, they share all matters related to the society, hence everyone knows what's going on. This is why collectiveness leads to a good society.

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

At stp which gas will diffuse more readily than ne
pav-90 [236]
I am assuming you are talking about Neon. The rate of diffusion is directly proportional to the molar mass of the gas. Since neon has a molar mass of 20.18 grams, the gas must have a lower molar mass and must be a gas at 273 Kelvin. There are several elements that fulfill this criteria: Hydrogen, Helium, Oxygen, Nitrogen, and Fluorine.

First, let's count mole of 10 g Calcium Carbonate

mole = Mass / Molecular Mass

Calcium Carbonate = CaCO₃

Molecular Mass = Ar Ca + Ar C + (3 x Ar O)

Molecular Mass = 40 + 12 + (3 x 16)

Molecular Mass = 100

next

Mole of CaCO₃ = 10 gram / 100

Mole of CaCO₃ = 0,1 mol

then equal the reaction equation first

 CaCO₃ + 2 HCl  ==>  CaCl₂ +  CO₂  +  H₂O     (Equal)

To count the mass of carbon dioxide that produced we must know the mole of CO₂ first

we can count by coefficient comparison

mole CO₂ = \frac{coefficient \ of \ CO_2}{coefficient \ of \ CaCO_3}  x mole CaCO₃

mole  CO₂ =  (1/1)  x 0,1 mole

mole  CO₂ = 0,1 mole

so

Mass of  CO₂ = mole  CO₂ x  Molecular Mass of  CO₂

Mass of  CO₂ = 0,1 mole x (12 + (2 x 16))

Mass of  CO₂ = 0,1 mole x 44

Mass of  CO₂ = 4,4 g

so, mass of carbon dioxide that's produced by 10 g of calcium carbonate on reaction with chloride acid is 4,4 g.

Barium acetate, Ba(C2H3O2)2, is a common barium salt that is highly poisonous. It was featured in a 2001 episode of Forensic Fil
aleksley [76]

Answer:

209.68

Explanation:

The only number that is relevant (though the rest are quite interesting) is the last one 1.98 * 10^24

1 mole of Barium Acetate Contains 6.02*10^23 particles.

There are 4 moles of carbon to every mole of Barium Acetate.

1.98 * 10^24 atoms / (4*6.02*10^23)

0.8223 moles of Ba(C2H3O2)2

Ba =                 137

4C = 4*12          48

6H = 6*1              6

4O = 4*16           64

1mole                 255 grams

0.8223 * 255 = 209.68 grams  

I have used rounded masses for these elements depending on the periodic table you use. Go through the question with your masses to get a more accurate answer. My answer will not differ by much. It is a guide.
