Nacl , or halite, dissolves in water. which type of bond is most abundant which allows it to dissolve?

1 answer:

3 0

Intermolecular bonding:
Water is a polar molecule exhibit dispersion forces and hydrogen bonding
Salt is a polar molecule exhibit dispersion forces and dipole dipole bonding

Same bonding capacity therefore similar bonding capacity, therefore salt able to dissolves in water

A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa. If Po2 =

HACTEHA [7]

Answer:

A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.

<u>The pressure for oxygen is 3 kPa</u>

Explanation:

According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.

$P_{total}=P_{1}+P_{2}+P_{3}$

So,

For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:

$P_{total}=P_{O_{2}}+P_{N_{2}}+P_{CO_{2}}$

$P_{total} = 32.5kPa$

$P_{O_{2}} = 6.5kPa$

$P_{N_{2}} = 23.0kPa$

Insert the values in :

$P_{total}=P_{O_{2}}+P_{N_{2}}+P_{CO_{2}}$

$32.5 kPa = 6.5 kPa + 23.0 kPa +P_{CO_{2}}$

$32.5 kPa = 29.5 kPa +P_{CO_{2}}$

$P_{CO_{2}}= 32.5 - 29.5$

$P_{CO_{2}}= 3kPa$

Answer:

1) pentane is of higher Molecular mass than propane hence heavier member

2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight

3) I) in methanol C = sp3

ii) in methanoic acid C= sp2

5)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bond

Lithium-4 and Lithium-5 can be defined as:

Ludmilka [50]

Answer:

A: isotopes

Explanation:

Hello.

In this case, since isotopes are defined as atoms of the same element with the same atomic number (number of protons and electrons) but different mass number (atomic mass) we can represent them via the symbol of the element followed by a dash indicating the atomic mass of the occurring isotope, for instance, for carbon, we may find C-12, C-13 and even C-14 which is useful in dating techniques.

Therefore, Lithium-4 or Li-4 and Lithium-5 or Li-5 can be defined as isotopes.

Best regards.
