DIPOLES FORM AT EACH BOND BETWEEN HYDROGEN AND OXYGEN IN A WATER MOLECULE BECAUSE _

Chemistry
1 answer:
mafiozo [28]2 years ago
7 0

Answer:

Dipole form on each bond between hydrogen and oxygen atom in water molecule because of the electronegativity difference

between hydrogen and oxygen.

Explanation : Electronegativity means attraction of shared pair of electron toward itself in the covalent bond. Those atoms having same electronegativity values, the shared electron remain in the center whereas those atoms having different electronegativity values, the shared pair of electron is attracted by the atom having high value of electronegativity. In water molecule, electronegativity of oxygen is higher so it attracts electron pair towards itself and forms negative pole and hydrogen aquire positive pole.

How many grams of product might form for the following reaction if 33.8 L of Oxygen gas is used in the following reaction? LiCl
nata0808 [166]

Answer:

91.41 g of LiClO₃.

Explanation:

We'll begin by calculating the number of mole of O₂ that occupied 33.8 L. This can be obtained as follow:

22.4 L = 1 mole of O₂

Therefore,

33.8 L = 33.8 L × 1 mole / 22.4 L

33.8 L = 1.51 mole of O₂

Next, the balanced equation for the reaction.

2LiCl + 3O₂ —> 2LiClO₃

From the balanced equation above,

3 moles of O₂ reacted to produce 2 moles of LiClO₃.

Therefore, 1.51 mole of O₂ will react to produce = (1.51 × 2)/3 = 1.01 mole of LiClO₃.

Finally, we shall determine the mass of 1.01 mole of LiClO₃. This can be obtained as follow:

Mole of LiClO₃ = 1.01 mole

Molar mass of LiClO₃ = 7 + 35.5 + (3×16)

= 7 + 35.5 + 48

= 90.5 g/mol

Mass of LiClO₃ =?

Mass = mole × molar mass

Mass of LiClO₃ = 1.01 × 90.5

Mass of LiClO₃ = 91.41 g

Thus, 91.41 g of LiClO₃ were obtained from the reaction.

Describe in detail what you know about the enthalpy, entropy, and free energy changes when a sample of gas condenses to a liquid
ycow [4]
The keyword here is gas condenses to a liquid, which mean we're talking about condensation process

The enthalpy energy in condensation process is negative because it releases energy
The entropy in general will also decreases .

Temperature affect this change because it will create free energy if added with this result

hope this helps
