Answer:

D. They are different from the properties of carbon, oxygen, and hydrogen.

Step-by-step explanation:

Carbon, oxygen, and hydrogen are all elements.

Sucrose is a compound containing carbon, oxygen, and hydrogen. Its properties are different from those of its elements.

For example, carbon is a black solid, while oxygen and hydrogen are colourless gases. Sucrose is a white solid.

Which of the following causes the formation of ionic bonds

pantera1 [17]

Answer: b. One atom transferring electrons to another atom

Explanation: An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.

Covalent bonds are formed by sharing of electrons between non metals

For example, In calcium iodide the one electron from calcium metal gets transferred to iodine atom and thus form an ionic bond to give $CaI_2$

Electronic configuration of calcium:

$[Ca]=1s^22s^22p^63s^23p^64s^2$

Calcium atom will lose two electron to gain noble gas configuration and form calcium cation with +2 charge.

$[Ca^{2+}]=1s^22s^22p^63s^23p^6$

Electronic configuration of iodine:

$[I]=1s^22s^22p^63s^23p^64s^23d^{10}4p^5$

Iodine atom will gain one electron to gain noble gas configuration and form iodide ion with -1 charge.

$[I^-]=1s^22s^22p^63s^23p^64s^23d^{10}4p^6$

How much energy (in joules) is released when 0.06 kilograms of mercury is condensed to a liquid at the same temperature? A. 51,3

expeople1 [14]

The amount of energy released when 0.06 kg of mercury condenses at the same temperature can be calculated using its latent heat of fusion which is the opposite of melting. Latent heat of fusion and melting can be used because they have the same magnitude, but opposite signs. Latent heat is the amount of energy required to change the state or phase of a substance. For latent heat, there is no temperature change. The equation is:

E = m(ΔH)

where:
m = mass of substance
ΔH = latent heat of fusion or melting

According to data, the ΔH of mercury is approximately 11.6 kJ/kg.

E = 0.06kg (11.6 kJ/kg) = 0.696 kJ or 696 J

The answer is D. 697.08 J. Note that small differences could be due to rounding off or different data sources.
