How many grams is 1.2 moles of Neon?

Answers

Mass of Neon : = 24.21564 g

Further explanation

Given

1.2 moles of Neon

Required

mass of Neon

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

Mol = mass : Molar mass

so mass of Neon(MM=20,1797 g/mol) :

= mol x MM

= 1.2 x 20,1797

= 24.21564 g

To show the electron configuration for an atom, when would it be better to use an orbital notation than to use a written configuration with numbers, letters, and superscripts? when the aim is to show orbital shapes in subshells
when the aim is to show electron distributions in shells

Answers

The answer is: when the aim is to show electron distributions in shells

An orbital notation is more appropriate if you want to show how the electrons of an atom are distributed in each subshell. This is because there are some atoms that have special electronic configurations that aren't obvious in just written configurations.

Explanation:

Many breads arc made by adding yeast to dough, causing the dough to rise. Yeast is a type of microorganism that produces the catalyst zymase, which converts glucose, C6H12O6' to ethanol and carbon dioxide gas. The balanced equation for this reaction is shown below.C6H12O6(aq) 2 C2H5OH(aq) + 2 CO2(g)

73 Draw a structural formula for the ethanol formed during this reaction.
74 Describe how the catalyst, zymase, speeds up this reaction.
75 Determine the total mass of ethanol produced when 270. grams of glucose reacts completely to form ethanol and 132 grams of carbon dioxide.

Answers

73. Ethanol has 2 carbons connected to each other. One carbon has 3 H attached and the other atom has 2 H attached and an -OH attachment 
      H   H
       l     l
H - C - C - OH
       l     l
      H    H

74. Activation energy is lowered. 
75. Note: MW glucose is 180g/mol ; MW ethanol is 46 g/mol; there is 2 moles of ethanol produced by one mole of glucose. 

g glucose= 270 glucose (1mol/180g)(2mole ethanol/1mol glucose)(46g/mol)= 138 g ethanol
