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

Answers

Answer 1

Answer:

Free electrons

Explanation:

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

Answer 2

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.

Answers

Answer: smaller, larger

Explanation:

Cations are always {smaller} than the parent atom. Anions are always {larger} than the parent atom.

Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

What is parent atom ?

The term "parent atom" refers to an atom that has not yet undergone any chemical transformation. A parent atom is one that is discovered in its initial state.

Because they contain fewer electrons while maintaining the same nuclear charge, cations are always smaller than their parent atoms. Because the protons in the nucleus are holding the remaining electrons more tightly, their radii are less than those of the parent atoms. In the case of anion, this is the opposite.

Due to variations in electron-electron repulsion, the ionic radii of cations and anions are always less or bigger than the parent atom, respectively. The trends in ionic radius follow those in atomic size.

Thus, Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

balance CHCl3 + O2 = CO2 + H2O + Cl2

Answers

Answer:

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Explanation:

Left Hand Side(LHS)

We have CHCl3 and O2

Right Hand Side(RHS)

We have CO2, H2O and Cl2

Balancing

To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2

H2O remains the same

Before CO2 put 2 giving 2CO2

To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)

Combining all;

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Some copper is palced in a previouly weighted crucible and reweighed .
Mass of crucible + copper = 5.92g
Mass of crucible = 4.65g
Clculate the mass of copper used in the experiment

Answers

Answer:  1.27g (mass of Copper)

Explanation:

We can find the mass of copper by finding the difference between the mass of the crucible and the copper, and just the crucible. This is possible since the mass that is left would be attributed to just the copper.

Mass of copper = (Mass of crucible + copper) - Mass of crucible

                          = 5.92 g - 4.65 g

                          = 1.27 g

I don’t know what recording station you’re referring to but, When seismic waves reach the seismograph, a graphical record, or seismogram, is produced

Explanation:

The seismic waves hitting the recording station has been resulted in the seismograph, that has been evident of the earthquake.

The seismic wave has been the radiation, with the result of the movement of the earth surface. The movement has been result in the earthquake.

The intensity of the earthquake has been measured by seismograph on the Richter scale. The seismic wave results in the movement of the leads to the production of the seismograph.

Explanation:

Sulphuric acid (H2SO4) is titrated against 25.00cm3 of 0.200 mol/dm3 Sodium hydroxide solution (NaOH). It is found that 23.20 cm3 of sulphuric acid is required for neutralization. Calculate the concentration of Sulphuric acid

Answers

My answer,
Approximately 0.108 mol dm^-3

Explanations,
1. Make the balance chemical equation
2. Convert the 25 cm^3 to 0.025 dm^3 by multiplying 25 with 10^-3 (or 25 / 1000)
3. Concentration is equal to = moles of substance over volume of solution
4. Calculate how many number of moles present in 0.025dm^3 of sulphuric acid.

Mole = concentration x volume
^ rearranged from conc = mole/volume

Mole = 0.200 x 0.025 = 0.005 mol

5. Use the balance chemical equation ad mole ratio. In this case,

H2SO4 + 2NaOH —> 2H2O + Na2(SO4)

Thus the ratio between Sulphuric acid and Sodium Hydroxide is 1:2

Hence, the mole of H2SO4 is 0.005/2 = 0.0025 mol

6. Calculate the concentration of the sulphuric acid by using conc. = mole/volume

Hence the answer is 0.0025/(23.20 x 10^-3) = 0.108 mol dm^-3 rounded off at the 3 Sigfigs

What is the mass of phosphorus that contains twice the number of atoms found in 14

[Relative atomic mass : P = 31; Fe = 56]

Answers

Answer:

15.5 gm

Explanation:

What is the mass of phosphorus that contains twice the number of atoms found in 14 g of iron?

[Relative atomic mass : P = 31; Fe = 56]

14 gm Fe = 14gm/ 56 gm/mole = 14 mole gm/56gm = 14/56 mole

0.25 moles

2 X 0.25 = 0.5 moles

1 mole P = 31 gm

so

0.5 moles P =31/2 =15.5 gm
