A compound is found to be 38.76% calcium, 19.97% phosphorous and 41.28% oxygen. What is the empirical formula for this compound?
motikmotik

The empirical formula is Ca₃P₂O₈.

<em>Assume</em> that you have 100 g of the compound.

Then you have 38.76 g Ca, 19.97 g P, and 41.28 g O.

Now, we must convert these <em>masses to moles</em> and <em>find their ratio</em>s.

If the number in the ratio are not close to integers, you <em>multiply them by a numbe</em>r that makes them close to integers.

From here on, I like to summarize the calculations in a table.

<u>Element</u>  <u>Mass/g</u>     <u> Moles  </u>      <u> </u><u>Ratio </u>    <u>   ×2    </u>   <u>Integers</u>  

     Ca       38.76      0.967 07     1.4998   2.9995         3

     P         19.97       0.644 82     1             2                   2

     O        41.28       2.580 0       4.0011   8.0023          8

The empirical formula is Ca₃P₂O₈.

A real gas behaves least like an ideal gas under the conditions of
Montano1993 [528]

Answer: Option (2) is the correct answer.

Explanation:

A real gas behaves least like an ideal gas under the conditions of low temperature and high pressure.

This is because at low temperature and high pressure molecules of gas will have negligible kinetic energy and strong force of attraction. Thus, real gas will not behave like an ideal gas.

Whereas at high temperature and low pressure a real gas will behave like an ideal gas.

I need help like extremely bad
Anna007 [38]

Answer:

First start with the ones we know

Explanation:

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3.dna- is all the chromosomes (genetic material)

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell

a pair - so must be bigger than one chromosome

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

now 5.

A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

5. genome - all the DNA

Calcium carbide reacts with water to produce acetylene gas according to the following equation: CaC2(s) + 2H2O(l)C2H2(g) + Ca(OH
gtnhenbr [62]

Answer: The number of moles of CaC_2 reacted was 0.229

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = Total pressure - vapor pressure of water = (749 - 23.8) mm Hg= 725.2 mm Hg = 0.954 atm    (760mmHg= 1atm)

V = Volume of gas = 5.87 L

n = number of moles = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =25^0C=(25+273)K=298K

n=\frac{PV}{RT}

n=\frac{0.954atm\times 5.87L}{0.0821 L atm/K mol\times 298K}=0.229moles

CaC_2(s)+2H_2O(l)\rightarrow C_2H_2(g)+Ca(OH)_2(aq)

According to stoichiometry:

1 mole of C_2H_2 is produced by = 1 mole of CaC_2

Thus 0.229 moles of C_2H_2 is produced by = \frac{1}{1}\times 0.229=0.229 moles of CaC_2

Thus number of moles of CaC_2 reacted was 0.229
