At STP, how many moles of carbon dioxide will occupy 35.2 L of space?

Answer:

Moles of carbon dioxide are 1.57

Explanation:

Using ideal gas law, you can find moles of a gas with its pressure, temperature and volume, thus:

PV = nRT

PV/RT = n

<em>Where P is pressure, V is volume (35.2L); R is gas constant (0.082atmL/molK); T is absolute temperature and n are moles</em>

At STP, temperature is 273.15K and pressure is 1atm

Replacing:

1atm×35.2L / 0.082atmL/molK×273.15K = n

<em>1.57 = n</em>

<em>Moles of carbon dioxide are 1.57</em>

Why are most organic compounds nonconducting and insoluble in water?
maksim [4K]
I think the correct answers from the choices listed above are the second and the last options. Organic compounds are nonducting and insoluble in water because of the bonds that these compounds contain. Most organic compounds don't dissolve in water because they are nonpolar. They don't conduct electricity because they are covalent, not ionic.

Finding mole ratios from chemical formulae
Levart [38]

7 moles of oxygen are in the sample.

According to the chemical formula, each mole of nickel tetracarbonyl contains 4 moles of C atoms. Simply convert it into a fraction by putting the original solution in the denominator and the diluted solution in the numerator if you need to determine the concentration ratio between two solutions. The V/n ratio for each gas must be the same if the two gases are at the same temperature and pressure. The volume ratio of two gases at the same temperature and pressure is equal to their molar ratio. The mole ratio of C to O is 1 : 1

the bond angle marked a in the following molecule is about . question 24 options: a) 109.5 b) 180 c) 60 d) 120 e) 90
Sophie [7]

The bond angle marked as ‘a’ in the molecule above is about: D. 120 degrees. That means the angle between the atoms forms a trigonal planar shape.

<h3>What is the bond angle?</h3>

The bond angle is an angle between two bonds that measures in degrees and is calculated by using the spectroscopic method. The bond angle depends on the bonds and the number of lone pairs an atom has.

The molecule above contains 3 electron charge clouds around them: a single bond to carbon, a single bond to oxygen, and a double bond to the other oxygen. Hence, the O-C=O bond angle from the molecule above is 120 degrees.
