Answer:

There would be 1.47 x 10^24 carbon atoms in the sample.

Explanation:

If I've understoof the question, you mean you have a sample of C3H8 that contains 3.92 x 10^24 H atoms and want to know how many carbon atoms there are in that sample.

You can figure that out using the ratio of C atoms to H atoms, 3:8.

3.92 x 10^24 H atoms x 3 C atoms/8 H atoms = 1.47 x 10^24 C atoms

What is the molarity of 122.5 g of AlCl3 in 1.0 L of solution? (MM = 133 g/mol)

yawa3891 [41]

Answer: Molarity is defined as moles of solute per liter of solution. So, find the moles of solute and divide by the liters of solution.
molar mass AlCl3 = 133g/mole
moles AlCl3 = 127 g x 1 mole/133 g = 0.955 moles
liters of solution = 400 ml x 1 liter/1000 ml = 0.400 liters
Molarity = 0.955 moles/0.400 liters = 2.39 M

Calculate the enthalpy of formation of butane, C4H10, using the balanced chemical

melisa1 [442]

Answer:

-125.4

Explanation:

Target equation is 4C(s) + 5H2(g) = C4H10

These are the data equations for enthalpy of combustion

C(s) + O2(g) =O2(g) -393.5 kJ/mol * 4
H2(g) + ½O2(g) =H20(l) = 285.8 kJ/mol * 5
2CO2(g) + 3H2O(l) = 13/2O2 (g) + C4H10 - 2877.1 reverse

To get target equation multiply data equation 1 by 4; multiply equation 2 by 5; and reverse equation 3, so...

Calculate 4(-393.5) + 5(-285.8) + 2877.6 and you should get the answer.

The partial negative charge at one end of a water molecule is attracted to the partial positive

Neporo4naja [7]

Answer:

Hydrogen Bond

Explanation:

Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.

In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.
