Graphite conducts heat in a similar way to metals because it contains __________ __________. What two words complete the sentence?

Answers

Answer:

Free electrons

Explanation:

Graphite conducts heat in a similar way to metals because it contains free electrons.

Conductivity is arised from the delocalization of free electrons. Metals are electron rich and conduct thermally and electrically. Graphite conducts heat in a similar way because it contain delocalized electrons.

What is graphite?

Graphite is an allotrope of carbon as diamond and fullerenes. Graphite exhibits a  layered  helical structures in which the carbon atoms are arranged in a hexagonal fashion.

Substances conduct electricity and heat when they are rich in electrons and are mobile to pass through it. Metals are electropositive and they contains extra electrons which can be delocalized between orbitals or energy levels.

This delocalization of electrons results in an a thermal or electrical current in the substance. Carbon is in sp2 hybridisation in graphite. Where, the electrons can transit from one layer to the other in the layered structure.

Therefore, the presence of delocalized electrons make graphite conducting.

Explanation:

Element X is in group 2, and element Y is in group 7, of the periodic table. which ions will be present in the compound formed when X and Y react together?

A) X^+ and Y^-
B)X^2+ and Y^-
C)X^+ and Y^2-
D)X^2- and Y^+

Answers

Answer:

Element X has valency 2 while Y Valency 2, element Y has high tendency of gaining electrons for its stability thus the compound formed will be B

elements X is positively charged while Y will be negatively charged

The groups or the families in the periodic table are denoted by the vertical column. Element in group 2 and 7 forms compound with ions ⁺ and Y⁻. Thus, option B is correct.

What is the periodic group?

A group of the periodic table is also called a family that has the elements placed togther with the same number of the valence electron. Group II has two valence electrons and VII has seven valence electrons in the outer shells.

The two valence electrons of the atom can be donated easily compared to acquiring the six electrons to complete the octet and stability. Similarly, the seven valence electrons are hard to donate but can accept one electron to achieve satbility.

The group II element X will donate its two electrons to acquire a +2 charge, whereas group VII element Y will accept one electron and acquire a -1 charge.

Therefore, option B.  X²⁺ and Y⁻ presents the ions of the compound.

Unfortunately, this is a poorly asked question and none of the answers are truly right. The closest one to correct is C, although this can’t be deduced from this experiment alone.

A is not correct - other elements can produce spectral lines (and even if they couldn’t, this experiment wouldn’t be able to determine that).

B is not correct - elements produce different spectral lines based on the number of protons that are in the nucleus, amongst a number of other things (again, this wouldn’t be able to be determined from this experiment alone).

D is also not correct, hydrogen is a gas at room temperature and the production of the spectral lines comes from ionizing the gas itself.

Why is knowledge of the activity series crucial in choosing which metal to build things with?

Answers

Answer:

activity series is a list of substances ranked in order of relative reactivity.

For example, magnesium metal can displace hydrogen ions from solution. So magnesium is more reactive than hydrogen:

Mg(s) + 2H⁺(aq) → H₂(g) + Mg²⁺(aq)

Zinc metal can also displace hydrogen ions from solution:

Zn(s) + 2H⁺(aq) → H₂(g) + Zn²⁺(aq)

so zinc is also more active than hydrogen.

But magnesium metal can displace zinc ions from solution:

Mg(s) + Zn²⁺(aq) → Zn(s) + Mg²⁺(aq)

so magnesium is more active than zinc.

The activity series including these elements would be Mg > Zn > H.

Chemists have built up a complete activity series in a similar way.

The most active metals are at the top of the table; the least active are at the bottom.

Any metal that is higher in the series will displace a metal that is below it in a

The knowledge of the activity series in choosing which metal to build things with because; it provides a basis for determining which metal ion is able to displace the other upon chemical interaction.

The choice of building material is a very important design consideration.

This is so because careful consideration must be taken while deciding which metal to build things with as the reactivity of metals vary.

This variation is carefully quantified by the position of metals on the activity series.

​Figure 5 shows how the temperature of a substance changed as it was heated. Which segment of the graph indicates that the substance was undergoing a change of state?

Answers

answer:

B

Why:

Because when heated up, the particles vibrate from the heat and keep on vibrating.

at point b of the diagram, the energy is gone to breaking bonds of the (let's assume) solid.

So there is no change in temperature.

I hope this helps please let me know if you need me to explain more.

When temperature is changing with respect to the time in the given graph, then substance B was undergoing a change of state.

What is change of state?

When any substance converts from one form of matter to the other form, then this phenomenon is known as change of state.

In the given figure a graph represents the change in temperature of substances A, B, C and D with respect to the time. Temperature of the substances A, C & D keep continuous changing with respect to the time. But substance B shows change in state because it absorbs the heat to convert in another state by breaking old bonds and making new bonds and showing showing no change in temperature.

Hence, substance B was undergoing a change of state.

11) When sodium metal is subjected to violet light, it causes the photoelectric effect. However, red light does not affect
the sodium. Explain this phenomena.

Answers

The phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.

The phenomenon in which a substance emits electrons when light is incident upon it is called the photoelectric effect.

This electron would not be emitted if the frequency of the light does not exceed a minimum frequency called the threshold frequency.

Since in the case of the sodium metal, violet light causes the photoelectric effect while red light does not.

This implies that red light does not exceed the minimum frequency for the photoelectric effect to occur, but violet light does thereby causing the photoelectric effect to occur.

So, the phenomena in which violet light causes photoelectric effect and red light does not is because red light does not achieve the minimum frequency for the phenomenon to occur but violet light does.
