Why does Buckminsterfullerene, with a formula of C60, have a simple covalent structure instead of a giant covalent structure?
Answer:
HOPE THIS HELPS
Explanation:
They are made up of large molecules so are not classed as giant covalent networks . Weak intermolecular forces exist between buckyballs. These need little energy to overcome, so substances consisting of buckyballs are slippery and have lower melting points than graphite or diamond .
If force of 6.0 N causes a 1.0 kg block to accelerate 4.0 m/s2 to
the right, then what is the force of friction acting on the block?
The force of friction acting on the block is -2N.
To find the force of a friction, the given datas are,
Force = 6N
Mass = 1 kg
Acceleration = 4 m/s².
What is the force of friction?The push or pull on an object that made the changes in the velocity with the mass. The object's or body's is to be at motion or at rest will be determined by Force. It has both the magnitude and direction.
The Net Force of the object can be written by:
Fnet = ma
where m is the mass of the object in kg
a is the acceleration of the object in m/s^2
Substituting the values in the formula,
Fnet = (1.0)(4.0)
= 4 N
We also know that Net force is also the sum of all forces acting on an object. In this case Friction and the Pushing Force is acting on the object. Hence we can write that:
Fnet = Pushing Force + (-Friction)
6N = 4 N - Friction
Friction = - 2N
Hence the force of friction is -2 N.

identify the particles that facilitate the electric conductivity of sodium metal
Answer:
Sodium metal will conduct electricity in both a solid and liquid state, due to 'a sea' of delocalised electrons which can move and are able to carry charge
Sodium metal will conduct electricity only when it is in a liquid state or in solution because of the ionic state which are free to move in this state, allowing them to carry charge and conduct electricity.
What are free electrons ?An electron within a conducting substance (as in a Sodium metal) but not permanently attached to any atom.

Which type of chemical reaction occurs in ca cl2 right arrow. cacl2? synthesis combustion single replacement double replacement
The type of chemical reaction occurs when calcium and chloride reacts to form calcium chloride is synthesis reaction.
What is synthesis reaction?Synthesis reaction is also known by the name of combination reaction in which two reactants combine for the formation of the product.
Given chemical reaction is also a synthesis reaction as in that calcium and chloride reacts with each other for the formation of calcium chloride as:
Ca + Cl₂ → CaCl₂
Combustion reaction are those in which carbon dioxide and water is produced, but in given reaction that is not happening so that was not combustion reaction.In replacement reaction one atom of any reactant will replace by another atom, but this is not the case in given reaction.In double replacemnt two atoms or molecules will replace, so given reaction is not that.Hence given chemical reaction is a synthesis reaction.

An unknown amount of gas has a volume of 12 L and a pressure of 5.6 atm. If the temperature is 205K, how many moles of gas are present
The number of moles of the gas present is 4 moles.
To calculate the numbers of moles of the gas present, we use the formula below.
Formula:
PV = nRT............. Equation 1Where:
P = PressureV = Volumen = Number of moles of the gasR = molar gas constantT = Temperature.Make n the subject of the equation
n = PV/RT............ Equation 2From the question,
Given:
P = 5.6 atmV = 12 LT = 205 KR = 0.0821 L.atm.K⁻¹.mol⁻¹Substitute these values into equation 2
n = (5.6×12)/(0.0821×205)n = 67.2/16.8305n = 3.99n ≈ 4 molesHence, the number of moles of the gas present is 4 moles.

Increasing the concentration of a reactant shifts the position of chemical equilibrium towards formation of more products. What effect does adding a reactant have on the rates of the forward and reverse reactions?.
Answer:
A.There is no effect on the forward and reverse reactions. For an equilibrium reaction, the forward and reverse rates are always equal.
B. Both the forward and reverse reactions speed up by the same amount.
C. The forward reaction speeds up immediately. As more product is made, the reverse reaction starts to speed up as the forward reaction starts to slow down until they are equal.
D. The forward reaction slows down initially. As the reaction proceeds, the reverse reaction slows down to meet the new forward reaction.
E. The forward reaction speeds up. Eventually, production of the product speeds up the reverse reaction rate to match the new forward rate.
F. It is impossible to say without more specific information.

If your sample of vinegar is approximately 4.76% (w/w), what volume should you use so that approximately 40 mL of 0.1 M NaOH is required to neutralize your sample of vinegar
Based on the concentrations given, the volume of vinegar required is 5.04 mL.
What is the concentration of the vinegar solution?The concentration of a solution is the amount of solute in a given volume of solution.
Concentration can be expressed as:
molar concentration percentage concentrationThe concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.
Mass of vinegar = 4.76 g
molar mass if vinegar = 60 g/mol
moles of vinegar = 4.76/60 = 0.0793 moles
volume of solution/water = 100 mL or 0.1 L
Molarity of vinegar = 0.0793/0.1 = 0.793 M
1 mole of vinegar reacts with 1 mole of NaOH
let the volume of vinegar required be V
0.793 M × V = 40 × 0.1
V = 4/0.793
V = 5.04 mL
Therefore, the volume of vinegar require is 5.04 mL.
