If you were to microwave a bowl of soup for too long and you burn your hands as you remove the bowl from the microwave, the heat transfer that would be demonstrated would be called: conduction. Conduction occurs when heat from one substance comes in contact in another substance. Just like when heat from the bowl came in contact with your hand.

With what elements does nitrogen form ionic bonds?
Andrew [12]

Answer:

Group 1 and 2 elements

Explanation:

Nitrogen, a non-metal will form ionic bonds with most group 1 and group 2 metals on the periodic table.

How does ionic bonds form?

  • They are bonds formed between a highly electronegative specie and one with very low electronegativity.
  • As such, ionic bonds forms between metals and non-metals
  • In this bond type, the metal due to its electropositive nature will transfer electrons to the non-metals for it to gain.
  • The non-metals becomes negatively charged as the metal is positively charged.
  • The electrostatic attraction between the two specie leads to the formation of ionic bonds.

Most metals in group 1 and 2 fits in this description. Some of them are calcium, magnesium, lithium, Barium e.t.c.

It mostly favors group 2 metals.

Calculate the mass percent of Cl in Freon -112 (C2 Cl4 F2), a CFC refrigerant
Karolina [17]

Answer:

The answer to your question is:  69.6 %

Explanation:

Freon -112 (C₂Cl₄F₂)

MW = (12 x 2) + (35.5 x 4) + (19 x 2)

      = 24 + 142 + 38

      = 204 g

                       204 g of C₂Cl₄F₂  -----------------  100%

                       142 g                     -----------------   x

                      x = (142 x 100 ) / 204

                      x = 69.6 %

Explain how dalton’s atomic theory offered a convincing explanation of the observation that mass is conserved in chemical reacti
podryga [215]

Dalton's atomic theory was based on the law of conservation of mass which states that the matter can neither be created nor be destroyed but it can only transformed into one form or another. In a chemical reaction, total mass of the reactants will be equal to the total mass of the products.

Taking an example,

methane+oxygen\rightarrow \text{carbon dioxide}+water

CH_4+2O_2\rightarrow CO_2+2H_2O

Mass of CH_4 = 16g

Mass of 2O_2 = 2\times 32g

Total mass on reactant side = (16+2\times 32)

Total mass on reactant side = 80g

Mass of CO_2 = 44g

Mass of 2H_2O=2\times 18g

Total mass on product side = (44+2\times 18)

Total mass on product side = 80g

It is seen from the above example that the

total mass on reactant side = total mass on product side.
