Chemistry

Komok [63]3 years ago

Explanation:

2H_2O_2 \rightarrow 2H_2O + O_2

First convert the amount of water into moles:

360 g H2O × \left(\dfrac{1\:\text{mol}H_2O}{18.015\:\text{g}H_2O}\right)

= 20. \:\text{mol}H_2O

Now let's calculate the number of moles of O2 gas produced.

20 mol H2O × \left(\dfrac{1\:\text{mol}O_2}{2\:\text{mol}H_2O}\right)=10\:\text{mol}O_2

The volume of gas at 10°C and 5 atm can be found using the ideal gas law:

PV=nRT

V= \dfrac{nRT}{P}

= \dfrac{(10)(0.082)(283)}{(5)}=46.4\:L

Difference between dipole dipole and hydrogen bonding
riadik2000 [5.3K]

Hydrogen bonds are stronger than the dipole dipole attraction force present in any molecule.

<h3>What is bonding in molecules?</h3>

Bonding is a type of attraction force which is present between the different atoms or elements of any substance.

  • Dipole dipole attraction force is a weak force as compared to the hydrogen bonding and present between any two oppositely charged atoms.
  • Hydrogen bond is present between the hydrogen atom and more electronegative atoms like O, S, N and F.

Hence main difference is that hydrogen bond is only present between the hydrogen atom and more electronegative.

1. The following reaction does not proceed to form a product: H2O + Au---&gt; no reaction. Why is that?
Xelga [282]
1. B
The positive charge in water is provided by hydrogen, and gold provides the same charge. However, gold is not more reactive than hydrogen so it can not replace it in the compound.

2. In order to balance the equation, you must sure there are equal moles of each element on the left and right side of the equation:
2C₂H₆ + 7O₂ → 4CO₂ + ₆H₂O

3. The number of moles of sodium atoms on the left of the equation must be equal to the number of moles of sodium atoms on the right, as per the law of conservation of mass. The answer is B.

4. C.
A synthesis reaction usually results from single displacement because some element or compound is produced in its pure form

5. B. 
The gas being produced is being synthesized.

Among the intermolecular forces,which forces are typically the weakest
nekit [7.7K]

Answer:

The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
